 Output Format
 : See [Custom Output Formats](/templates/output-formats). An output format has both a `name` (e.g. `rss`, `amp`, `html`) and a `suffix` (e.g. `xml`, `html`). We prefer matches with both (e.g. `index.amp.html`, but look for less specific templates.
 
+Note that if the output format's Media Type have more than one suffix defined, only the first is considered.

 Language
 : We will consider a language code in the template name. If the site language is `fr`, `index.fr.amp.html` will win over `index.amp.html`, but `index.amp.html` will be chosen before `index.fr.html`.
