+
+Hugo has become a fully featured static site generator, so any new functionality must:
+
+* be useful to many.
+* fit naturally into _what Hugo does best._
+* strive not to break existing sites.
+* close or update an open [Hugo issue](https://github.com/gohugoio/hugo/issues)
+
+If it is of some complexity, the contributor is expected to maintain and support the new future (answer questions on the forum, fix any bugs etc.).
+
+It is recommended to open up a discussion on the [Hugo Forum](https://discourse.gohugo.io/) to get feedback on your idea before you begin. If you are submitting a complex feature, create a small design proposal on the [Hugo issue tracker](https://github.com/gohugoio/hugo/issues) before you start.

-### Vendored Dependencies
-
-Hugo uses [govendor](https://github.com/kardianos/govendor) to vendor dependencies, but we don't commit the vendored packages themselves to the Hugo git repository.
-Therefore, a simple `go get` is not supported since `go get` is not vendor-aware.
-You **must use govendor** to fetch and manage Hugo's dependencies.

 Hugo fork is to use Git Remotes.  Here's a simple walk-through for getting

+
+    ```bash

+    Note that Hugo uses [Go Dep](https://github.com/golang/dep) to vendor dependencies, rather than a simple `go get`. We don't commit the vendored packages themselves to the Hugo git repository. The call to `mage vendor` takes care of all this for you.

-### Build Hugo with Your Changes
+### Building Hugo with Your Changes
+
+Hugo uses [mage](https://github.com/magefile/mage) to sync vendor dependencies, build Hugo, run the test suite and other things. You must run mage from the Hugo directory.
 
 ```bash
 cd $HOME/go/src/github.com/gohugoio/hugo
-make hugo
-# or to install in $HOME/go/bin:
-make install
 ```
 
+To build Hugo: 
+
+```bash
+mage hugo
+```
+
+To install hugo in `$HOME/go/bin`:
+
+```bash
+mage install

+
+To run the tests:
+
+```bash
+mage hugoRace
+mage -v check
+```
+
+To list all available commands along with descriptions:
+
+```bash
+mage -l
+```
+
+**Note:** From Hugo 0.43 we have added a build tag, `extended` that adds **SCSS support**. This needs a C compiler installed to build. You can enable this when building by:
+
+```bash
+HUGO_BUILD_TAGS=extended mage install
+````
+
 ### Updating the Hugo Sources
 
 If you want to stay in sync with the Hugo repository, you can easily pull down
 the source changes, but you'll need to keep the vendored packages up-to-date as
 well.

+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.

+
+      "Derivative Works" shall mean any work, whether in Source or Object

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and

+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,

+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,

+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+   APPENDIX: How to apply the Apache License to your work.

 ### Build and Install the Binaries from Source (Advanced Install)
 
-Add Hugo and its package dependencies to your go `src` directory.
+#### Prerequisite Tools
 
-    go get -v github.com/gohugoio/hugo
+* [Git](https://git-scm.com/)
+* [Go (latest or previous version)](https://golang.org/dl/)
 
-Once the `get` completes, you should find your new `hugo` (or `hugo.exe`) executable sitting inside `$GOPATH/bin/`.
+#### Vendored Dependencies
 
-To update Hugo’s dependencies, use `go get` with the `-u` option.
+Hugo uses [dep](https://github.com/golang/dep) to vendor dependencies, but we don't commit the vendored packages themselves to the Hugo git repository. Therefore, a simple `go get` is _not_ supported because the command is not vendor aware.
 
-    go get -u -v github.com/gohugoio/hugo
+The simplest way is to use [mage](https://github.com/magefile/mage) (a Make alternative for Go projects.)
+
+#### Fetch from GitHub
+
+```bash
+go get github.com/magefile/mage
+go get -d github.com/gohugoio/hugo
+cd ${GOPATH:-$HOME/go}/src/github.com/gohugoio/hugo
+mage vendor
+mage install
+```
+
+**If you are a Windows user, substitute the `$HOME` environment variable above with `%USERPROFILE%`.**

 ## Contributing

 *Pull requests shall **only** contain changes to the actual documentation. However, changes on the code base of Hugo **and** the documentation shall be a single, atomic pull request in the [hugo](https://github.com/gohugoio/hugo) repository.*
 
+Spelling fixes are most welcomed, and if you want to contribute longer sections to the documentation, it would be great if you had these in mind when writing:
+
+* Short is good. People go to the library to read novels. If there is more than one way to _do a thing_ in Hugo, describe the current _best practice_ (avoid "… but you can also do …" and "… in older versions of Hugo you had to …".
+* For examples, try to find short snippets that teaches people about the concept. If the example is also useful as-is (copy and paste), then great, but don't list long and similar examples just so people can use them on their sites.
+* Hugo has users from all over the world, so an easy to understand and [simple English](https://simple.wikipedia.org/wiki/Basic_English) is good.
+
+## Branches
+
+* The `master` branch is where the site is automatically built from, and is the place to put changes relevant to the current Hugo version.
+* The `next` branch is where we store changes that is related to the next Hugo release. This can be previewed here: https://next--gohugoio.netlify.com/

-In no particular order, here are some other features currently being worked on:
-
-* Even easier deployment to S3, SSH, GitHub, rsync. Give the [hosting and deployment][] section a shot.
-* Import from other website systems. There are already [existing migration tools][migrate], but they don’t cover all major platforms.
-* An interactive web-based editor (See the [related forum thread][])
-* Additional [themes][], which are always ongoing and [contributions are welcome][themescontrib]!
-* Dynamic image resizing via shortcodes ({{< gh 1014 >}})
-* Native support for additional content formats (AsciiDoc {{< gh 1435>}}, reST {{< gh 1436 >}})
-* And, last but not least, [***your*** best ideas!][]

-## hugo server
-
-A high performance webserver
-
-### Synopsis
-
-
-Hugo provides its own webserver which builds and serves the site.
-While hugo server is high performance, it is a webserver with limited options.
-Many run it in production, but the standard behavior is for people to use it
-in development and use a more full featured server such as Nginx or Caddy.
-
-'hugo server' will avoid writing the rendered and served content to disk,
-preferring to store it in memory.
-
-By default hugo will also watch your files for any changes you make and
-automatically rebuild the site. It will then live reload any open browser pages
-and push the latest content to them. As most Hugo sites are built in a fraction
-of a second, you will be able to save and see your changes nearly instantly.

-
-## What are Archetypes?
-
-**Archetypes** are content files in the [archetypes directory][] of your project that contain preconfigured [front matter][] for your website's [content types][]. Archetypes facilitate consistent metadata across your website content and allow content authors to quickly generate instances of a content type via the `hugo new` command.
-
-{{< youtube S3Tj3UcTFz8 >}}
-
-The `hugo new` generator for archetypes assumes your working directory is the content folder at the root of your project. Hugo is able to infer the appropriate archetype by assuming the content type from the content section passed to the CLI command:
-
-```
-hugo new <content-section>/<file-name.md>
-```
-
-We can use this pattern to create a new `.md` file in the `posts` section:
-
-{{< code file="archetype-example.sh" >}}
-hugo new posts/my-first-post.md
-{{< /code >}}
-
-{{% note "Override Content Type in a New File" %}}
-To override the content type Hugo infers from `[content-section]`, add the `--kind` flag to the end of the `hugo new` command.
-{{% /note %}}
-
-Running this command in a new site that does not have default or custom archetypes will create the following file:
-
-{{< output file="content/posts/my-first-post.md" >}}
-+++
-date = "2017-02-01T19:20:04-07:00"
-title = "my first post"
-draft = true
-+++
-{{< /output >}}
-
-{{% note %}}
-In this example, if you do not already have a `content/posts` directory, Hugo will create both `content/posts/` and `content/posts/my-first-post.md` for you.
-{{% /note %}}
-
-The  auto-populated fields are worth examining:
-
-* `title` is generated from the new content's filename (i.e. in this case, `my-first-post` becomes `"my first post"`)
-* `date` and `title` are the variables that ship with Hugo and are therefore included in *all* content files created with the Hugo CLI. `date` is generated in [RFC 3339 format][] by way of Go's [`now()`][] function, which returns the current time.
-* The third variable, `draft = true`, is *not* inherited by your default or custom archetypes but is included in Hugo's automatically scaffolded `default.md` archetype for convenience.
-
-Three variables per content file are often not enough for effective content management of larger websites. Luckily, Hugo provides a simple mechanism for extending the number of variables through custom archetypes, as well as default archetypes to keep content creation DRY.
-
-## Lookup Order for Archetypes
-
-Similar to the [lookup order for templates][lookup] in your `layouts` directory, Hugo looks for a section- or type-specific archetype, then a default archetype, and finally an internal archetype that ships with Hugo. For example, Hugo will look for an archetype for `content/posts/my-first-post.md` in the following order:
-
-1. `archetypes/posts.md`
-2. `archetypes/default.md`
-3. `themes/<THEME>/archetypes/posts.md`
-4. `themes/<THEME>/archetypes/default.md` (Auto-generated with `hugo new site`)
-
-{{% note "Using a Theme Archetype" %}}
-If you wish to use archetypes that ship with a theme, the `theme` field must be specified in your [configuration file](/getting-started/configuration/).
-{{% /note %}}
-
-## Choose Your Archetype's Front Matter Format
-
-By default, `hugo new` content files include front matter in the TOML format regardless of the format used in `archetypes/*.md`.
-
-You can specify a different default format in your site [configuration file][] file using the `metaDataFormat` directive. Possible values are `toml`, `yaml`, and `json`.
-
-## Default Archetypes
-
-Default archetypes are convenient if your content's front matter stays consistent across multiple [content sections][sections].
-
-### Create the Default Archetype
-
-When you create a new Hugo project using `hugo new site`, you'll notice that Hugo has already scaffolded a file at `archetypes/default.md`. 
-
-The following examples are from a site that's using `tags` and `categories` as [taxonomies][]. If we assume that all content files will require these two key-values, we can create a `default.md` archetype that *extends* Hugo's base archetype. In this example, we are including "golang" and "hugo" as tags and "web development" as a category.
-
-{{< code file="archetypes/default.md" >}}
-+++
-tags = ["golang", "hugo"]
-categories = ["web development"]
-+++
-{{< /code >}}
-
-{{% warning "EOL Characters in Text Editors"%}}
-If you get an `EOF error` when using `hugo new`, add a carriage return after the closing `+++` or `---` for your TOML or YAML front matter, respectively. (See the [troubleshooting article on EOF errors](/troubleshooting/eof-error/) for more information.)
-{{% /warning %}}
-
-### Use the Default Archetype
-
-With an `archetypes/default.md` in place, we can use the CLI to create a new post in the `posts` content section:
-
-{{< code file="new-post-from-default.sh" >}}
-$ hugo new posts/my-new-post.md
-{{< /code >}}
-
-Hugo then creates a new markdown file with the following front matter:
-
-{{< output file="content/posts/my-new-post.md" >}}
-+++
-categories = ["web development"]
-date = "2017-02-01T19:20:04-07:00"
-tags = ["golang", "hugo"]
-title = "my new post"
-+++
-{{< /output >}}
-
-We see that the `title` and `date` key-values have been added in addition to the `tags` and `categories` key-values from `archetypes/default.md`.
-
-{{% note "Ordering of Front Matter" %}}
-You may notice that content files created with `hugo new` do not respect the order of the key-values specified in your archetype files. This is a [known issue](https://github.com/gohugoio/hugo/issues/452).
-{{% /note %}}
-
-## Custom Archetypes
-
-Suppose your site's `posts` section requires more sophisticated front matter than what has been specified in `archetypes/default.md`. You can create a custom archetype for your posts at `archetypes/posts.md` that includes the full set of front matter to be added to the two default archetypes fields.
-
-### Create a Custom Archetype
-
-{{< code file="archetypes/posts.md">}}
-+++
-description = ""
-tags = ""
-categories = ""
-+++
-{{< /code >}}
-
-### Use a Custom Archetype
-
-With an `archetypes/posts.md` in place, you can use the Hugo CLI to create a new post with your preconfigured front matter in the `posts` content section:
-
-{{< code file="new-post-from-custom.sh" >}}
-$ hugo new posts/post-from-custom.md
-{{< /code >}}
-
-This time, Hugo recognizes our custom `archetypes/posts.md` archetype and uses it instead of `archetypes/default.md`. The generated file will now include the full list of front matter parameters, as well as the base archetype's `title` and `date`:
-
-{{< output file="content/posts/post-from-custom-archetype.md" >}}
-+++
-categories = ""
-date = 2017-02-13T17:24:43-08:00
-description = ""
-tags = ""
-title = "post from custom archetype"
-+++
-{{< /output >}}
-
-### Hugo Docs Custom Archetype
-
-As an example of archetypes in practice, the following is the `functions` archetype from the Hugo docs:
-
-{{< code file="archetypes/functions.md" >}}
-{{< readfile file="/themes/gohugoioTheme/archetypes/functions.md" >}}
-{{< /code >}}
-
-{{% note %}}
-The preceding archetype is kept up to date with every Hugo build by using Hugo's [`readFile` function](/functions/readfile/). For similar examples, see [Local File Templates](/templates/files/).

-description: Hugo makes it easy to link documents together.

----
-
-
- The `ref` and `relref` shortcodes link documents together, both of which are [built-in Hugo shortcodes][]. These shortcodes are also used to provide links to headings inside of your content, whether across documents or within a document. The only difference between `ref` and `relref` is whether the resulting URL is absolute (`http://1.com/about/`) or relative (`/about/`), respectively.
-
-## Use `ref` and `relref`
-
-```
-{{</* ref "document" */>}}
-{{</* ref "#anchor" */>}}
-{{</* ref "document#anchor" */>}}
-{{</* relref "document" */>}}
-{{</* relref "#anchor" */>}}
-{{</* relref "document#anchor" */>}}
-```
-
-The single parameter to `ref` is a string with a content `documentname` (e.g., `about.md`) with or without an appended in-document `anchor` (`#who`) without spaces.
-
-### Document Names
-
-The `documentname` is the name of a document, including the format extension; this may be just the filename, or the relative path from the `content/` directory. With a document `content/blog/post.md`, either format will produce the same result:
-
-```
-{{</* relref "blog/post.md" */>}} => `/blog/post/`
-{{</* relref "post.md" */>}} => `/blog/post/`
-```
-
-If you have the same filename used across multiple sections, you should only use the relative path format; otherwise, the behavior will be `undefined`. This is best illustrated with an example `content` directory:
-
-```
-.
-└── content
-    ├── events
-    │   └── my-birthday.md
-    ├── galleries
-    │   └── my-birthday.md
-    ├── meta
-    │   └── my-article.md
-    └── posts
-        └── my-birthday.md
-```
-
-To be sure to get the correct reference in this case, use the full path: 
-
-{{< code file="content/meta/my-article.md" copy="false" >}}
-{{</* relref "events/my-birthday.md" */>}} => /events/my-birthday/
-{{< /code >}}
-
-{{< todo >}}Remove this warning when https://github.com/gohugoio/hugo/issues/3703 is released.{{< /todo >}}
-
-A relative document name must *not* begin with a slash (`/`).
-```
-{{</* relref "/events/my-birthday.md" */>}} => ""
-```
-
-### With Multiple Output Formats
-
-If the page exists in multiple [output formats][], `ref` or `relref` can be used with a output format name:
-
-```
- [Neat]({{</* ref "blog/neat.md" "amp" */>}})
-```
-
-### Anchors
-
-When an `anchor` is provided by itself, the current page’s unique identifier will be appended; when an `anchor` is provided appended to `documentname`, the found page's unique identifier will be appended:
-
-```
-{{</* relref "#anchors" */>}} => #anchors:9decaf7
-{{</* relref "about-hugo/hugo-features.md#content" */>}} => /blog/post/#who:badcafe
-```
-
-The above examples render as follows for this very page as well as a reference to the "Content" heading in the Hugo docs features pageyoursite
-
-```
-{{</* relref "#who" */>}} => #who:9decaf7
-{{</* relref "blog/post.md#who" */>}} => /blog/post/#who:badcafe
-```
-
-More information about document unique identifiers and headings can be found [below]({{< ref "#hugo-heading-anchors" >}}).
-
-### Examples
-
-* `{{</* ref "blog/post.md" */>}}` => `https://example.com/blog/post/`
-* `{{</* ref "post.md#tldr" */>}}` => `https://example.com/blog/post/#tldr:caffebad`
-* `{{</* relref "post.md" */>}}` => `/blog/post/`
-* `{{</* relref "blog/post.md#tldr" */>}}` => `/blog/post/#tldr:caffebad`
-* `{{</* ref "#tldr" */>}}` => `#tldr:badcaffe`
-* `{{</* relref "#tldr" */>}}` => `#tldr:badcaffe`
-
-## Hugo Heading Anchors
-
-When using Markdown document types, Hugo generates heading anchors automatically. The generated anchor for this section is `hugo-heading-anchors`. Because the heading anchors are generated automatically, Hugo takes some effort to ensure that heading anchors are unique both inside a document and across the entire site.
-
-Ensuring heading uniqueness across the site is accomplished with a unique identifier for each document based on its path. Unless a document is renamed or moved between sections *in the filesystem*, the unique identifier for the document will not change: `blog/post.md` will always have a unique identifier of `81df004c333b392d34a49fd3a91ba720`.
-
-`ref` and `relref` were added so you can make these reference links without having to know the document’s unique identifier. (The links in document tables of contents are automatically up-to-date with this value.)
-
-```
-{{</* relref "content-management/cross-references.md#hugo-heading-anchors" */>}}

-

-DefaultContentLanguage = "en"
-copyright = "Everything is mine"
-

-help  = "Aide"
-{{< /code >}}

-Anything not defined in a `[Languages]` block will fall back to the global
-value for that key (e.g., `copyright` for the English [`en`] language).
-
-With the configuration above, all content, sitemap, RSS feeds, paginations,
-and taxonomy pages will be rendered below `/` in English (your default content language) and then below `/fr` in French.
-
-When working with front matter `Params` in [single page templates][singles], omit the `params` in the key for the translation.

-If you want all of the languages to be put below their respective language code, enable `defaultContentLanguageInSubdir: true`.
-
-Only the obvious non-global options can be overridden per language. Examples of global options are `baseURL`, `buildDrafts`, etc.
-
-## Taxonomies and Blackfriday
-
-Taxonomies and [Blackfriday configuration][config] can also be set per language:
-
-
-{{< code file="bf-config.toml" >}}
-[Taxonomies]
-tag = "tags"
-
-[blackfriday]
-angledQuotes = true
-hrefTargetBlank = true
-
-[Languages]
-[Languages.en]
-weight = 1
-title = "English"
-[Languages.en.blackfriday]
-angledQuotes = false
-
-[Languages.fr]
-weight = 2
-title = "Français"
-[Languages.fr.Taxonomies]
-plaque = "plaques"
-{{< /code >}}
-
-## Translate Your Content
-
-Translated articles are identified by the name of the content file.
-
-### Examples of Translated Articles
-
-1. `/content/about.en.md`
-2. `/content/about.fr.md`
-
-In this example, the `about.md` will be assigned the configured `defaultContentLanguage`. 
-
-1. `/content/about.md`
-2. `/content/about.fr.md`
-
-This way, you can slowly start to translate your current content without having to rename everything. If left unspecified, the default value for `defaultContentLanguage` is `en`.
-
-By having the same *base filename*, the content pieces are linked together as translated pieces.
-
-If you need distinct URLs per language, you can set the slug in the non-default language file. For example, you can define a custom slug for a French translation in the front matter of `content/about.fr.md` as follows:
-
-```
-slug: "a-propos"
-
-```
-
-At render, Hugo will build both `/about/` and `/a-propos/` as properly linked translated pages.
-
-{{%note %}}
-Hugo currently uses the base filename as the translation key, which can be an issue with identical filenames in different sections.
-We will fix this in https://github.com/gohugoio/hugo/issues/2699
-{{% /note %}}
-{{< todo >}}Rewrite/remove the above one issue is fixed.{{< /todo >}}
-
-## Link to Translated Content
-
-To create a list of links to translated content, use a template similar to the following:
-
-{{< code file="layouts/partials/i18nlist.html" >}}
-{{ if .IsTranslated }}
-<h4>{{ i18n "translations" }}</h4>
-<ul>
-    {{ range .Translations }}
-    <li>
-        <a href="{{ .Permalink }}">{{ .Lang }}: {{ .Title }}{{ if .IsPage }} ({{ i18n "wordCount" . }}){{ end }}</a>
-    </li>
-    {{ end}}
-</ul>
-{{ end }}
-{{< /code >}}
-
-The above can be put in a `partial` (i.e., inside `layouts/partials/`) and included in any template, be it for a [single content page][contenttemplate] or the [homepage][]. It will not print anything if there are no translations for a given page, or if there are translations---in the case of the homepage, section listing, etc.---a site with only render one language.
-
-The above also uses the [`i18n` function][i18func] described in the next section.
-
-## Translation of Strings
-
-Hugo uses [go-i18n][] to support string translations. [See the project's source repository][go-i18n-source] to find tools that will help you manage your translation workflows.
-
-Translations are collected from the `themes/<THEME>/i18n/` folder (built into the theme), as well as translations present in `i18n/` at the root of your project. In the `i18n`, the translations will be merged and take precedence over what is in the theme folder. Language files should be named according to [RFC 5646][] with names such as `en-US.toml`, `fr.toml`, etc.
-
-From within your templates, use the `i18n` function like this:
-
-```
-{{ i18n "home" }}
-```
-
-This uses a definition like this one in `i18n/en-US.toml`:
-
-```
-[home]
-other = "Home"
-```
-
-Often you will want to use to the page variables in the translations strings. To do that, pass on the "." context when calling `i18n`:
-
-```
-{{ i18n "wordCount" . }}
-```
-
-This uses a definition like this one in `i18n/en-US.toml`:
-
-```
-[wordCount]
-other = "This article has {{ .WordCount }} words."
-```
-An example of singular and plural form:
-
-```
-[readingTime]
-one = "One minute read"
-other = "{{.Count}} minutes read"
-```
-And then in the template:
-
-```
-{{ i18n "readingTime" .ReadingTime }}
-```
-To track down missing translation strings, run Hugo with the `--i18n-warnings` flag:
-
-```
- hugo --i18n-warnings | grep i18n
-i18n|MISSING_TRANSLATION|en|wordCount
-```
-
-## Customize Dates
-
-At the time of this writing, Golang does not yet have support for internationalized locales, but if you do some work, you can simulate it. For example, if you want to use French month names, you can add a data file like ``data/mois.yaml`` with this content:
-
-~~~yaml
-1: "janvier"
-2: "février"
-3: "mars"
-4: "avril"
-5: "mai"
-6: "juin"
-7: "juillet"
-8: "août"
-9: "septembre"
-10: "octobre"
-11: "novembre"
-12: "décembre"
-~~~
-
-... then index the non-English date names in your templates like so:
-
-~~~html
-<time class="post-date" datetime="{{ .Date.Format "2006-01-02T15:04:05Z07:00" | safeHTML }}">
-  Article publié le {{ .Date.Day }} {{ index $.Site.Data.mois (printf "%d" .Date.Month) }} {{ .Date.Year }} (dernière modification le {{ .Lastmod.Day }} {{ index $.Site.Data.mois (printf "%d" .Lastmod.Month) }} {{ .Lastmod.Year }})
-</time>
-~~~
-
-This technique extracts the day, month and year by specifying ``.Date.Day``, ``.Date.Month``, and ``.Date.Year``, and uses the month number as a key, when indexing the month name data file.
-
-## Menus
-
-You can define your menus for each language independently. The [creation of a menu][menus] works analogous to earlier versions of Hugo, except that they have to be defined in their language-specific block in the configuration file:
-
-```
-defaultContentLanguage = "en"
-
-[languages.en]
-weight = 0
-languageName = "English"
-
-[[languages.en.menu.main]]
-url    = "/"
-name   = "Home"
-weight = 0
-
-
-[languages.de]
-weight = 10
-languageName = "Deutsch"
-
-[[languages.de.menu.main]]
-url    = "/"
-name   = "Startseite"
-weight = 0
-```
-
-The rendering of the main navigation works as usual. `.Site.Menus` will just contain the menu of the current language. Pay attention to the generation of the menu links. `absLangURL` takes care that you link to the correct locale of your website. Otherwise, both menu entries would link to the English version as the default content language that resides in the root directory.
-
-```
-<ul>
-    {{- $currentPage := . -}}
-    {{ range .Site.Menus.main -}}
-    <li class="{{ if $currentPage.IsMenuCurrent "main" . }}active{{ end }}">
-        <a href="{{ .URL | absLangURL }}">{{ .Name }}</a>
-    </li>
-    {{- end }}
-</ul>
-
-```
-
-## Missing translations
-
-If a string does not have a translation for the current language, Hugo will use the value from the default language. If no default value is set, an empty string will be shown.
-
-While translating a Hugo website, it can be handy to have a visual indicator of missing translations. The [`enableMissingTranslationPlaceholders` configuration option][config] will flag all untranslated strings with the placeholder `[i18n] identifier`, where `identifier` is the id of the missing translation.
-
-{{% note %}}
-Hugo will generate your website with these missing translation placeholders. It might not be suited for production environments.
-{{% /note %}}
-
-## Multilingual Themes support
-
-To support Multilingual mode in your themes, some considerations must be taken for the URLs in the templates. If there is more than one language, URLs must meet the following criteria:
-
-* Come from the built-in `.Permalink` or `.URL`
-* Be constructed with
-    * The [`relLangURL` template function][rellangurl] or the [`absLangURL` template function][abslangurl] **OR**
-    * Prefixed with `{{ .LanguagePrefix }}`
-
-If there is more than one language defined, the `LanguagePrefix` variable will equal `/en` (or whatever your `CurrentLanguage` is). If not enabled, it will be an empty string and is therefore harmless for single-language Hugo websites.

-{{% /note %}}
-{{% todo %}}
-See above
-{{% /todo %}}
-
-Hugo believes that you organize your content with a purpose. The same structure that works to organize your source content is used to organize the rendered site (see [directory structure][]).
-
-Following this pattern, Hugo uses the top level of your content organization as the content **section**.
-
-The following example shows a content directory structure for a website that has three sections: "authors," "events," and "posts":
-
-```
-.
-└── content
-    ├── authors
-    |   ├── _index.md     // <- example.com/authors/
-    |   ├── john-doe.md   // <- example.com/authors/john-doe/
-    |   └── jane-doe.md   // <- example.com/authors/jane-doe/
-    └── events
-    |   ├── _index.md     // <- example.com/events/
-    |   ├── event-1.md    // <- example.com/events/event-1/
-    |   ├── event-2.md    // <- example.com/events/event-2/
-    |   └── event-3.md    // <- example.com/events/event-3/
-    └── posts
-    |   ├── _index.md     // <- example.com/posts/
-    |   ├── event-1.md    // <- example.com/posts/event-1/
-    |   ├── event-2.md    // <- example.com/posts/event-2/
-    |   ├── event-3.md    // <- example.com/posts/event-3/
-    |   ├── event-4.md    // <- example.com/posts/event-4/
-    |   └── event-5.md    // <- example.com/posts/event-5/
-```
-
-## Content Section Lists
-
-Hugo will automatically create pages for each section root that list all of the content in that section. See the documentation on [section templates][] for details on customizing the way these pages are rendered.
-
-As of Hugo v0.18, section pages can also have a content file and front matter. These section content files must be placed in their corresponding section folder and named `_index.md` in order for Hugo to correctly render the front matter and content.
-
-{{% warning "`index.md` vs `_index.md`" %}}
-Hugo themes developed before v0.18 often used an `index.md`(i.e., without the leading underscore [`_`]) in a content section as a hack to emulate the behavior of `_index.md`. The hack may work...*sometimes*; however, the order of page rendering can be unpredictable in Hugo. What works now may fail to render appropriately as your site grows. It is **strongly advised** to use `_index.md` as content for your section index pages. **Note:** `_index.md`'s layout, as representative of a section, is a [list page template](/templates/section-templates/) and *not* a [single page template](/templates/single-page-templates/). If you want to alter the new default behavior for `_index.md`, configure `disableKinds` accordingly in your [site's configuration](/getting-started/configuration/).
-{{% /warning %}}
-
-## Content *Section* vs Content *Type*
-
-By default, everything created within a section will use the [content type][] that matches the section name. For example, Hugo will assume that `posts/post-1.md` has a `posts` content type. If you are using an [archetype][] for your posts section, Hugo will generate front matter according to what it finds in `archetypes/posts.md`.
