 # Installation
 
-Packages are available for various distributions (see [Installation docs](https://docs.helix-editor.com/install.html)).
-
-If you would like to build from source:
-
-```shell
-git clone https://github.com/helix-editor/helix
-cd helix
-cargo install --locked --path helix-term
-```
-
-This will install the `hx` binary to `$HOME/.cargo/bin` and build tree-sitter grammars in `./runtime/grammars`.
-
-Helix needs its runtime files so make sure to copy/symlink the `runtime/` directory into the
-config directory (for example `~/.config/helix/runtime` on Linux/macOS, or `%AppData%/helix/runtime` on Windows).
-
-| OS                   | Command                                          |
-| -------------------- | ------------------------------------------------ |
-| Windows (Cmd)        | `xcopy /e /i runtime %AppData%\helix\runtime`    |
-| Windows (PowerShell) | `xcopy /e /i runtime $Env:AppData\helix\runtime` |
-| Linux / macOS        | `ln -s $PWD/runtime ~/.config/helix/runtime`     |
-
-Starting with Windows Vista you can also create symbolic links on Windows. Note that this requires
-elevated privileges - i.e. PowerShell or Cmd must be run as administrator.
-
-**PowerShell:**
-
-```powershell
-New-Item -ItemType Junction -Target "runtime" -Path "$Env:AppData\helix\runtime"
-```
-Note: "runtime" must be absolute path to the runtime directory.
-
-**Cmd:**
-
-```cmd
-cd %appdata%\helix
-mklink /D runtime "<helix-repo>\runtime"
-```
-
-The runtime location can be overridden via the `HELIX_RUNTIME` environment variable.
-
-> NOTE: if `HELIX_RUNTIME` is set prior to calling `cargo install --locked --path helix-term`,
-> tree-sitter grammars will be built in `$HELIX_RUNTIME/grammars`.
-
-If you plan on keeping the repo locally, an alternative to copying/symlinking
-runtime files is to set `HELIX_RUNTIME=/path/to/helix/runtime`
-(`HELIX_RUNTIME=$PWD/runtime` if you're in the helix repo directory).
-
-Packages already solve this for you by wrapping the `hx` binary with a wrapper
-that sets the variable to the install dir.
-
-> NOTE: running via cargo also doesn't require setting explicit `HELIX_RUNTIME` path, it will automatically
-> detect the `runtime` directory in the project root.
-
-If you want to customize your `languages.toml` config,
-tree-sitter grammars may be manually fetched and built with `hx --grammar fetch` and `hx --grammar build`.
-
-In order to use LSP features like auto-complete, you will need to
-[install the appropriate Language Server](https://github.com/helix-editor/helix/wiki/How-to-install-the-default-language-servers)
-for a language.

-## Adding Helix to your desktop environment
-
-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
-cp contrib/helix.png ~/.local/share/icons
-```
-
-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
-```
-
-## macOS
-
-Helix can be installed on macOS through homebrew:
-
-```
-brew install helix
-```
-
