+# 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 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
-
-On Debian-based distros running `apt install build-essential libpam0g-dev libxcb-xkb-dev` as root should install all the dependencies for you.
-For Fedora try running `dnf install make automake gcc gcc-c++ kernel-devel pam-devel libxcb-devel`
+- Compile-time:
+  - zig 0.12.0
+  - a C standard library
+  - pam
+  - xcb
+- Runtime (with default config):
+  - xorg
+  - xorg-xauth
+  - mcookie
+  - tput
+  - shutdown

-## Support
-The following desktop environments were tested with success
+### 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.
