+## Adding Helix to your desktop environment
 
-Helix can be installed on MacOS through homebrew:
+If installing from source, to use Helix in desktop environments that supports [XDG desktop menu](https://specifications.freedesktop.org/menu-spec/menu-spec-latest.html), including Gnome and KDE, copy the provided `.desktop` file to the correct folder:
+
+```bash
+cp contrib/Helix.desktop ~/.local/share/applications
+```
+
+To use another terminal than the default, you will need to modify the `.desktop` file. For example, to use `kitty`:
+
+```bash
+sed -i "s|Exec=hx %F|Exec=kitty hx %F|g" ~/.local/share/applications/Helix.desktop
+sed -i "s|Terminal=true|Terminal=false|g" ~/.local/share/applications/Helix.desktop

+a return expression always ends the block that it is in. Note that this only stops the
+extension of the next `@extend` capture. If multiple ancestors are captured,
+only the extension of the innermost one is prevented. All other ancestors are unaffected
+(regardless of whether the innermost ancestor would actually have been extended).

+### File-type detection and the `file-types` key
+
+Helix determines which language configuration to use with the `file-types` key
+from the above section. `file-types` is a list of strings or tables, for
+example:
+
+```toml
+file-types = ["Makefile", "toml", { suffix = ".git/config" }]
+```
+
+When determining a language configuration to use, Helix searches the file-types
+with the following priorities:
+
+1. Exact match: if the filename of a file is an exact match of a string in a
+   `file-types` list, that language wins. In the example above, `"Makefile"`
+   will match against `Makefile` files.
+2. Extension: if there are no exact matches, any `file-types` string that
+   matches the file extension of a given file wins. In the example above, the
+   `"toml"` matches files like `Cargo.toml` or `languages.toml`.
+3. Suffix: if there are still no matches, any values in `suffix` tables
+   are checked against the full path of the given file. In the example above,
+   the `{ suffix = ".git/config" }` would match against any `config` files
+   in `.git` directories. Note: `/` is used as the directory separator but is
+   replaced at runtime with the appropriate path separator for the operating
+   system, so this rule would match against `.git\config` files on Windows.
