+## 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:
 
-[Wayland Environments](#supported-wayland-environments)
+Every environment that works on other login managers also should work on Ly.
 
-[X11 Environments](#supported-x11-environments)
+- Unlike most login managers Ly has an xinitrc and shell entry.
 
-Ly should work with any X desktop environment, and provides
-basic wayland support (sway works very well, for example).
+- 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.
 
-## 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 :)
+- 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://codeberg.org/AnErrupTion/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 authentication won't work)
+After building, you can (optionally) test Ly in a terminal emulator, although authentication will **not** work:
+
 ```
 $ zig build run
 ```
 
-**Important**: Running Ly in a terminal emulator as root is *not* recommended. If you
-want to properly test Ly, please enable its service (as described below) and reboot
-your machine.
+> [!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:
 
-Install Ly for systemd-based systems (the default)
 ```
-# zig build installexe
+# zig build installexe -Dinit_system=systemd
 ```
 
-Instead of DISPLAY_MANAGER you need to add your DM:
-- gdm.service
-- sddm.service
-- lightdm.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 you are using LightDM, you can execute the following command:
+
 ```
-# systemctl disable DISPLAY_MANAGER
+# systemctl disable lightdm.service
 ```
 
-Enable the service
+Then, similarly to the previous command, you need to enable the Ly service:
+
 ```
-# systemctl enable ly.service
+# systemctl enable ly@tty2.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, you need to execute the following command:
+
 ```
 # systemctl disable getty@tty2.service
 ```
 
+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).
+
+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
-**NOTE 1**: 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 installexe -Dinit_system=openrc
-```
-
-Enable the service
-```
+# 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 2**: To avoid a console spawning on top on Ly, comment out the appropriate line from /etc/inittab (default is 2).
+> [!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/
-```
-
-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
-```
-
-Then, edit `/etc/s6/config/ttyX.conf` and set `SPAWN="no"`, where X is the TTY ID (e.g. `2`).
-
-Finally, enable the service:
-
-```
+# 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
 ```
 
-In addition to the steps above, you will also have to keep a TTY free within `/etc/dinit.d/config/console.conf`.
+To disable TTY 2, go to `/etc/dinit.d/config/console.conf` and modify `ACTIVE_CONSOLES`.
 
-To do that, change `ACTIVE_CONSOLES` so that the tty that ly should use in `/etc/ly/config.ini` is free.
+### 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
+```

+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).
