+Ly is a lightweight TUI (ncurses-like) display manager for Linux and BSD, designed with portability in mind and doesn't require systemd to run.
+
+Join us on Matrix over at [#ly-dm:matrix.org](https://matrix.to/#/#ly-dm:matrix.org)!
+
+> [!NOTE]
+> Development happens on [Codeberg](https://codeberg.org/fairyglade/ly) with a mirror on [GitHub](https://github.com/fairyglade/ly).
 
 ## 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.
+- Compile-time:
+  - zig 0.16.x
+
+  - libc
+
+  - pam
+
+  - xcb (optional, required by default; needed for X11 support)
+
+- Runtime (with default config):
+  - xorg
+
+  - xorg-xauth
+
+  - shutdown
+
+  - brightnessctl
+
+### Debian
+
+```
+# apt install build-essential libpam0g-dev libxcb-xkb-dev xauth xserver-xorg brightnessctl
+```
+
+### 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 zig xorg-x11-xauth xorg-x11-server brightnessctl
+```
+
+### FreeBSD
+
+```
+# pkg install ca_root_nss libxcb git xorg xauth
+```
+
+## Availability
+
+[![Packaging status](https://repology.org/badge/vertical-allrepos/ly-display-manager.svg?exclude_unsupported=1)](https://repology.org/project/ly-display-manager/versions)
 
 ## Support
-The following desktop environments were tested with success
- - budgie
- - cinnamon
- - deepin
- - enlightenment
- - gnome
- - i3
- - kde
- - lxde
- - lxqt
- - mate
- - sway
- - xfce
- - pantheon
- - maxx
- - windowmaker
 
-Ly should work with any X desktop environment, and provides
+Every environment that works on other login managers also should work on Ly.
-basic wayland support (sway works very well, for example).
 
-## systemd?
+- Unlike most login managers Ly has an xinitrc and shell entry.
-Unlike what you may have heard, Ly does not require `systemd`,
+
-and was even specifically designed not to depend on `logind`.
+- If you installed your favorite environment and you don't see it, that's because Ly doesn't automatically refresh itself. To fix this you should restart Ly service (depends on your init system) or the easy way is to reboot your system.
-You should be able to make it work easily with a better init,
+
-changing the source code won't be necessary :)
+- If your environment is still missing then check at `/usr/share/xsessions` or `/usr/share/wayland-sessions` to see if a .desktop file is present.
+
+- If there isn't a .desktop file then create a new one at `/etc/ly/custom-sessions` that launches your favorite environment. These .desktop files can be only seen by Ly and if you want them system-wide you also can create at those directories instead.
+
+- If Xorg sessions don't work then check if your distro compiles Ly with Xorg.
+
+Logs are defined by `/etc/ly/config.ini`:
+
+- The session log is located at `~/.local/state/ly-session.log` by default.
+
+- The system log is located at `/var/log/ly.log` by default.
+
+## Manually building
+
+The procedure for manually building Ly is pretty standard:
 
-## Cloning and Compiling
-Clone the repository
 ```
-git clone https://github.com/nullgemm/ly.git
+$ git clone https://codeberg.org/fairyglade/ly.git
+$ cd ly
+$ zig build
 ```
 
-Fetch submodules
+After building, you can (optionally) test Ly in a terminal emulator, although authentication will **not** work:
+
 ```
-make github
+$ zig build run
 ```
 
-Compile
+> [!IMPORTANT]
+> While you can run Ly in a terminal emulator as root, it is **not** recommended. If you want to test Ly, please enable its service (as described below) and reboot your machine.
+
+The next sections will explain how to use Ly with a variety of init systems. Detailed explanation is only given for systemd, but should be applicable for all.
+
+> [!NOTE]
+> All following sections will assume you are using LightDM for convenience sake.
+
+### systemd
+
+Now, you can install Ly on your system:
+
 ```
-make
+# zig build installexe -Dinit_system=systemd
 ```
 
-Test in the configured tty (tty2 by default)
+> [!NOTE]
-or a terminal emulator (but desktop environments won't start)
+> The `init_system` parameter is optional and defaults to `systemd`.
+
+Note that you also need to disable your current display manager. For example, if you are using LightDM, you can execute the following command:
+
 ```
-sudo make run
+# systemctl disable lightdm.service
 ```
 
-Install Ly and the provided systemd service file
+Then, similarly to the previous command, you need to enable the Ly service:
+
 ```
-sudo make install
+# systemctl enable ly@tty2.service
 ```
 
-Enable the service
+> [!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, you need to execute the following command:
+
 ```
-sudo systemctl enable ly.service
+# systemctl disable getty@tty2.service
 ```
 
-If you need to switch between ttys after Ly's start you also have to
+On platforms that use systemd-logind to dynamically start `autovt@.service` instances when the switch to a new tty occurs, any ly instances for ttys _except the default tty_ need to be enabled using a different mechanism: To autostart ly on switch to `tty2`, do not enable any `ly` unit directly, instead symlink `autovt@tty2.service` to `ly@tty2.service` within `/usr/lib/systemd/system/` (analogous for every other tty you want to enable ly on).
-disable getty on Ly's tty to prevent "login" from spawning on top of it
+
+The target of the symlink, `ly@ttyN.service`, does not actually exist, but systemd nevertheless recognizes that the instanciation of `autovt@.service` with `%I` equal to `ttyN` now points to an instanciation of `ly@.service` with `%I` set to `ttyN`.
+
+Compare to `man 5 logind.conf`, especially regarding the `NAutoVTs=` and `ReserveVT=` parameters.
+
+On non-systemd systems, you can change the TTY Ly will run on by editing the corresponding service file for your platform.
+
+### OpenRC
+
 ```
-sudo systemctl disable getty@tty2.service
+# zig build installexe -Dinit_system=openrc
+# rc-update del lightdm
+# rc-update add 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 installexe -Dinit_system=runit
+# rm /var/service/lightdm
+# ln -s /etc/sv/ly /var/service/
+# 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 overrding the current configuration file. This is called **updating**. To update, simply run:
+
+```
+# zig build installnoconf
+```
+
+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.

 ## 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
+- The numlock and capslock state is printed in the top-right corner.
-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

+- Use the F1 and F2 keys to respectively shutdown and reboot.
-The name "Ly" is a tribute to the fairy from the game Rayman.
+
-Ly was tested by oxodao, who is some seriously awesome dude.
+- Take a look at your `.xsession` file if X doesn't start, as it can interfere (this file is launched with X to configure the display properly).
+
+## A final note
+
+The name "Ly" is a tribute to the fairy from the game Rayman. Ly was tested by oxodao, who is some seriously awesome dude.
+
+Also, Ly wouldn't be there today without [ashametrine](https://github.com/ashametrine), who has done significant contributions to the project for the Zig rewrite, which lead to the release of Ly v1.0.0. Massive thanks, and sorry for not crediting you enough beforehand!

+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).
