-# 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/

 ## Support
-The following desktop environments were tested with success:
- - awesome
- - bspwm
- - budgie
- - cinnamon
- - deepin
- - dwl
- - dwm
- - enlightenment
- - gnome
- - i3
- - kde
- - labwc
- - lxde
- - lxqt
- - mate
- - maxx
- - pantheon
- - qtile
- - spectrwm
- - sway
- - windowmaker
- - xfce
- - xmonad
 
-Ly should work with any X desktop environment, and provides
-basic wayland support (sway works very well, for example).
+Ly has been tested with a wide variety of desktop environments and window
+managers, all of which you can find in the sections below:
 
-## systemd?
-Unlike what you may have heard, Ly does not require `systemd`,
-and was even specifically designed not to depend on `logind`.
-You should be able to make it work easily with a better init,
-changing the source code won't be necessary :)
+[Wayland environments](#supported-wayland-environments)
+
+[X11 environments](#supported-x11-environments)
+
+## Manually building
+
+The procedure for manually building Ly is pretty standard:
 
-## Cloning and Compiling
-Clone the repository
-```
-$ git clone https://github.com/fairyglade/ly
-```
-
-Change the directory to ly
 ```
+$ git clone https://codeberg.org/fairyglade/ly.git
 $ cd ly
-```
-
-Compile
-```
 $ zig build
 ```
 
-Test in the configured tty (tty2 by default)
-or a terminal emulator (but desktop environments won't start)
+After building, you can (optionally) test Ly in a terminal emulator, although
+authentication will **not** work:
+
 ```
-# zig build run
+$ zig build run
 ```
 
-Install Ly and the provided systemd service file
+**Important**: While you can also run Ly in a terminal emulator as root, it is
+**not** recommended either. If you want to properly test Ly, please enable its
+service (as described below) and reboot your machine.
+
+The following sections show how to install Ly for a particular init system.
+Because the procedure is very similar for all of them, the commands will only
+be detailed for the first section (which is about systemd).
+
+**Note**: All following sections will assume you are using LightDM for
+convenience sake.
+
+### systemd
+
+Now, you can install Ly on your system:
+
 ```
-# zig build installsystemd
+# zig build installexe -Dinit_system=systemd
 ```
 
-Enable the service
+**Note**: The `init_system` parameter is optional and defaults to `systemd`.
+
+Note that you also need to disable your current display manager. For example,
+if LightDM is the current display manager, you can execute the following
+command:
+
+```
+# systemctl disable lightdm.service
+```
+
+Then, similarly to the previous command, you need to enable the Ly service:
+
 ```
 # systemctl enable ly.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
+**Important**: Because Ly runs in a TTY, you **must** disable the TTY service
+that Ly will run on, otherwise bad things will happen. For example, to disable `getty` spawning on TTY 2 (the default TTY on which Ly spawns), you need to
+execute the following command:
+
 ```
 # systemctl disable getty@tty2.service
 ```
 
+You can change the TTY Ly will run on by editing the `tty` option in the
+configuration file **and** change which TTY is used in the corresponding
+service file..
+
 ### 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
 ```
+# zig build installexe -Dinit_system=openrc
+# rc-update del lightdm
 # 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
 ```
 
+**Note**: On Gentoo specifically, you also **must** comment out the appropriate
+line for the TTY in /etc/inittab.
+
 ### runit
+
 ```
-# zig build installrunit
+# zig build installexe -Dinit_system=runit
+# rm /var/service/lightdm
 # 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
 ```
 
+### s6
+
+```
+# zig build installexe -Dinit_system=s6
+# s6-rc -d change lightdm
+# s6-service add default ly-srv
+# s6-db-reload
+# s6-rc -u change ly-srv
+```
+
+To disable TTY 2, edit `/etc/s6/config/tty2.conf` and set `SPAWN="no"`.
+
+### dinit
+
+```
+# zig build installexe -Dinit_system=dinit
+# dinitctl disable lightdm
+# dinitctl enable ly
+```
+
+To disable TTY 2, go to `/etc/dinit.d/config/console.conf` and modify
+`ACTIVE_CONSOLES`.
+
+### sysvinit
+
+```
+# zig build installexe -Dinit_system=sysvinit
+# update-rc.d lightdm disable
+# update-rc.d ly defaults
+```
+
+To disable TTY 2, go to `/etc/inittab` and comment out the line containing `tty2`.
+
+### FreeBSD
+
+```
+# zig build installexe -Dprefix_directory=/usr/local -Dconfig_directory=/usr/local/etc -Dinit_system=freebsd
+# sysrc lightdm_enable="NO"
+```
+
+To enable Ly, add the following entry to `/etc/gettytab`:
+
+```
+Ly:\
+	:lo=/usr/local/bin/ly_wrapper:\
+	:al=root:
+```
+
+Then, modify the command field of the `ttyv1` terminal entry in `/etc/ttys`
+(TTYs in FreeBSD start at 0):
+
+```
+ttyv1 "/usr/libexec/getty Ly" xterm on secure
+```
+
 ### Updating
-You can also install Ly without copying the system service and the configuration file. That's
-called *updating*. To update, simply run:
+
+You can also install Ly without overrding the current configuration file. This
+is 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/):
-```
-$ sudo pacman -S ly
-```
+You can, of course, still select the init system of your choice when using this
+command.
 
 ## Configuration
-You can find all the configuration in `/etc/ly/config.ini`.
-The file is commented, and includes the default values.
+
+You can find all the configuration in `/etc/ly/config.ini`. The file is fully
+commented, and includes the default values.
 
 ## Controls
-Use the up and down arrow keys to change the current field, and the
-left and right arrow keys to change the target desktop environment
-while on the desktop field (above the login field).
 
-## .xinitrc
-If your .xinitrc doesn't work make sure it is executable and includes a shebang.
-This file is supposed to be a shell script! Quoting from xinit's man page:
+Use the Up/Down arrow keys to change the current field, and the Left/Right
+arrow keys to scroll through the different fields (whether it be the info line,
+the desktop environment, or the username). The info line is where messages and
+errors are displayed.
 
-> If no specific client program is given on the command line, xinit will look for a file in the user's home directory called .xinitrc to run as a shell script to start up client programs.
+## A note on .xinitrc
+
+If your `.xinitrc` file doesn't work ,make sure it is executable and includes a
+shebang. This file is supposed to be a shell script! Quoting from `xinit`'s man
+page:
+
+> If no specific client program is given on the command line, xinit will look
+> for a file in the user's home directory called .xinitrc to run as a shell
+> script to start up client programs.
+
+A typical shebang for a shell script looks like this:
 
-On Arch Linux, the example .xinitrc (/etc/X11/xinit/xinitrc) starts like this:
 ```
 #!/bin/sh
 ```
 
 ## Tips
-The numlock and capslock state is printed in the top-right corner.
-Use the F1 and F2 keys to respectively shutdown and reboot.
-Take a look at your .xsession if X doesn't start, as it can interfere
-(this file is launched with X to configure the display properly).
 
-## 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`.

+A custom session is just a desktop entry file, like for X11 and Wayland
+sessions. For example:
+
+[Desktop Entry]
+Name=Fish shell
+Exec=$PREFIX_DIRECTORY/bin/fish
+DesktopNames=null
+Terminal=true
+
+The DesktopNames value is optional and sets the XDG_SESSION_DESKTOP and
+XDG_CURRENT_DESKTOP environment variables. If equal to null or if not present,
+XDG_SESSION_DESKTOP and XDG_CURRENT_DESKTOP will not be set. Otherwise, the
+syntax is the same as described in the Freedesktop Desktop Entry Specification.
+
+The Terminal value specifies if standard output and standard error should be
+redirected to the session log file found in Ly's configuration file. If set to
+true, Ly will consider the program is going to run in a TTY, and thus will not
+redirect standard output & error. It is optional and defaults to false.
+
+Finally, do note that, if the Terminal value is set to true, the
+XDG_SESSION_TYPE environment variable will be set to "tty". Otherwise, it will
+be set to "unspecified" (without quotes), which is behavior that at least
+systemd recognizes (see pam_systemd's man page).
