+# 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`.
+
+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.

+# Termbox
+[Termbox](https://github.com/nsf/termbox)
+was a promising Text User Interface (TUI) library.
+Unfortunately, its original author
+[changed his mind](https://github.com/nsf/termbox/issues/37#issuecomment-261075481)
+about consoles and despite the
+[community's efforts](https://github.com/nsf/termbox/pull/104#issuecomment-300308156)
+to keep the library's development going, preferred to let it die. Before it happened,
+[some people](https://wiki.musl-libc.org/alternatives.html)
+already noticed the robustness of the initial architecture
+[became compromised](https://github.com/nsf/termbox/commit/66c3f91b14e24510319bce6b5cc2fecf8cf5abff#commitcomment-3790714)
+in a nonsensical refactoring frenzy. Now, the author refuses to merge features
+like true-color support, invoking some
+[spurious correlations](https://github.com/nsf/termbox/pull/104#issuecomment-300292223)
+we will discuss no further.
+
+## The new Termbox-next
+This fork was made to restore the codebase to its original quality (before
+[66c3f91](https://github.com/nsf/termbox/commit/66c3f91b14e24510319bce6b5cc2fecf8cf5abff))
+while providing all the functionnalities of the current implementation.
+This was achieved by branching at
+[a2e217f](https://github.com/nsf/termbox/commit/a2e217f0fb97e6bbd589136ea3945f9d5a123d81)
+and cherry-picking all the commits up to
+[d63b83a](https://github.com/nsf/termbox/commit/d63b83af04e0fd6da836bb8f37e5cec72a1dc95a)
+if they weren't harmful.
+
+## Changes
+A lot of things changed during the process:
+ - *waf*, the original build system, was completely removed from the
+   project and replaced by make.
+ - anything related to python was removed as well
+
+## Getting started
+Termbox's interface only consists of 12 functions:
+```
+tb_init() // initialization
+tb_shutdown() // shutdown
+
+tb_width() // width of the terminal screen
+tb_height() // height of the terminal screen
+
+tb_clear() // clear buffer
+tb_present() // sync internal buffer with terminal
+
+tb_put_cell()
+tb_change_cell()
+tb_blit() // drawing functions
+
+tb_select_input_mode() // change input mode
+tb_peek_event() // peek a keyboard event
+tb_poll_event() // wait for a keyboard event
+```
+See src/termbox.h header file for full detail.
+
+## TL;DR
+`make` to build a static version of the lib under bin/termbox.a
+`cd src/demo && make` to build the example programs in src/demo/

 # Ly - a TUI display manager
 ![Ly screenshot](https://user-images.githubusercontent.com/5473047/88958888-65efbf80-d2a1-11ea-8ae5-3f263bce9cce.png "Ly screenshot")
 
 Ly is a lightweight TUI (ncurses-like) display manager for Linux and BSD.
 
 ## Dependencies
- - a C99 compiler (tested with tcc and gcc)
- - a C standard library
- - GNU make
- - pam
- - xcb
- - xorg
- - xorg-xauth
- - mcookie
- - tput
- - shutdown
+- Compile-time:
+  - zig 0.12.0
+  - a C standard library
+  - pam
+  - xcb
+- Runtime (with default config):
+  - xorg
+  - xorg-xauth
+  - mcookie
+  - tput
+  - shutdown
 
-On Debian-based distros running `apt install build-essential libpam0g-dev libxcb-xkb-dev` as root should install all the dependencies for you.
+### Debian
+```
+# apt install build-essential libpam0g-dev libxcb-xkb-dev
+```
+
+### Fedora
+**Warning**: You may encounter issues with SELinux on Fedora.
+It is recommended to add a rule for Ly as it currently does not ship one.
+
+```
+# dnf install kernel-devel pam-devel libxcb-devel
+```

 Ly should work with any X desktop environment, and provides
 basic wayland support (sway works very well, for example).

 ## Cloning and Compiling
 Clone the repository
 ```
-git clone https://github.com/nullgemm/ly.git
+$ git clone https://github.com/fairyglade/ly
 ```
 
-Fetch submodules
+Change the directory to ly
 ```
-make github
+$ cd ly
 ```
 
 Compile
 ```
-make
+$ zig build
 ```
 
 Test in the configured tty (tty2 by default)
 or a terminal emulator (but desktop environments won't start)
 ```
-sudo make run
+# zig build run
 ```
 
 Install Ly and the provided systemd service file
 ```
-sudo make install
+# zig build installsystemd
 ```
 
-Enable the service
+Enable the service (this will spawn on tty2 and tty9)
 ```
-sudo systemctl enable ly.service
+# systemctl enable ly@tty2.service
+# systemctl enable ly@tty9.service
 ```
 
 If you need to switch between ttys after Ly's start you also have to
 disable getty on Ly's tty to prevent "login" from spawning on top of it
 ```
-sudo systemctl disable getty@tty2.service
+# systemctl disable getty@tty2.service
+```
+
+If you have multiple ttys setup with systemd, the tty option will be used as your default tty.
+
+### OpenRC
+**NOTE**: On Gentoo, Ly will disable the `display-manager-init` service in order to run.
+
+Clone, compile and test.
+
+Install Ly and the provided OpenRC service
+```
+# zig build installopenrc
+```
+
+Enable the service
+```
+# rc-update add ly
+```
+
+You can edit which tty Ly will start on by editing the `tty` option in the configuration file.
+
+If you choose a tty that already has a login/getty running (has a basic login prompt),
+then you have to disable getty, so it doesn't respawn on top of ly
+```
+# rc-update del agetty.tty2
+```
+
+### runit
+```
+# zig build installrunit
+# ln -s /etc/sv/ly /var/service/
+```
+
+By default, ly will run on tty2. To change the tty it must be set in `/etc/ly/config.ini` 
+
+You should as well disable your existing display manager service if needed, e.g.:
+
+```
+# rm /var/service/lxdm
+```
+
+The agetty service for the tty console where you are running ly should be disabled.
+For instance, if you are running ly on tty2 (that's the default, check your `/etc/ly/config.ini`)
+you should disable the agetty-tty2 service like this:
+
+```
+# rm /var/service/agetty-tty2
+```
+
+### Updating
+You can also install Ly without copying the system service and the configuration file. That's
+called *updating*. To update, simply run:
+
+```
+# zig build installnoconf
+```
+
+If you want to also copy the default config file (but still not the system service), run:
+
+```
+# zig build installexe
+```
+
+## Arch Linux Installation
+You can install ly from the [`[extra]` repos](https://archlinux.org/packages/extra/x86_64/ly/):
