+includeFiles (string or slice)
+: One or more [glob](https://github.com/gobwas/glob) patterns matching files or directories to include. If `excludeFiles` is not set, the files matching `includeFiles` will be the files mounted. 
+
+The glob patterns are matched to the filenames starting from the `source` root, they should have Unix styled slashes even on Windows, `/` matches the mount root and `**` can be used as a  super-asterisk to match recursively down all directories, e.g `/posts/**.jpg`.
