-# Zig Rewrite (Version 1.0.0)
-
-## Config Options
-
-res/config.ini contains all of the available config options and their default values.
-
-### Additions
-
-+ `border_fg` has been introduced to change the color of the borders.
-+ `term_restore_cursor_cmd` should restore the cursor to it's usual state.
-+ `vi_mode` to enable vi keybindings.
-+ `sleep_key` and `sleep_cmd`.
-+ `numlock` to set numlock on startup.
-+ `initial_info_text` allows changing the initial text on the info line.
-+ `box_title` to display a title at the top of the main box
-
-Note: `sleep_cmd` is unset by default, meaning it's hidden and has no effect. 
-
-### Changes
-
-+ xinitrc can be set to null to hide it.
-+ `blank_password` has been renamed to `clear_password`.
-+ `save_file` has been deprecated and will be removed in a future version.
-
-### Removals
-
-+ `wayland_specifier` has been removed.
-
-## Save File
-
-The save file is now in .ini format and stored in the same directory as the config.
-Older save files will be migrated to the new format.
-
-Example:
-
-```ini
-user = ash
-session_index = 0
-```
-
-## Misc
-
-+ Display server name added next to selected session.
-+ getty@tty2 has been added as a conflict in res/ly.service, so if it is running, ly should still be able to start.
-+ `XDG_CURRENT_DESKTOP` is now set by ly.
-+ LANG is no longer set by ly.
-+ X Server PID is fetched from /tmp/X{d}.lock to be able to kill the process since it detaches.
-+ Non .desktop files are now ignored in sessions directory.
-+ PAM auth is now done in a child process. (Fixes some issues with logging out and back in).
-+ When ly receives SIGTERM, the terminal is now cleared and existing child processes are cleaned up.
-+ Shift+Tab now focuses previous input.
-+ Display text in the info line when authenticating.

 You can install ly from the [`[extra]` repos](https://archlinux.org/packages/extra/x86_64/ly/):
 ```
-$ sudo pacman -S ly
+# pacman -S ly
+```
+
+## Gentoo Installation
+You can install ly from the GURU repository:
+
+Note: If the package is masked, you may need to unmask it using ~amd64 keyword:
+```bash
+# echo 'x11-misc/ly ~amd64' >> /etc/portage/package.accept_keywords
+```
+
+1. Enable the GURU repository:
+```bash
+# eselect repository enable guru
+```
+
+2. Sync the GURU repository:
+```bash
+# emaint sync -r guru
+```
+
+3. Install ly from source:
+```bash
+# emerge --ask x11-misc/ly
 ```

-## PSX DOOM fire animation
-To enable the famous PSX DOOM fire described by [Fabien Sanglard](http://fabiensanglard.net/doom_fire_psx/index.html),
-just uncomment `animate = true` in `/etc/ly/config.ini`. You may also
-disable the main box borders with `hide_borders = true`.
 
 ## Additional Information
 The name "Ly" is a tribute to the fairy from the game Rayman.
 Ly was tested by oxodao, who is some seriously awesome dude.
-
-## Gentoo (OpenRC) installation tip
-To avoid a console spawning on top on Ly, comment out the appropriate line from /etc/inittab (default is 2).
