+# Contributing to Ly
+
+To contribute to Ly, you have to open a pull request on [Codeberg](https://codeberg.org/fairyglade/ly), as [GitHub](https://github.com/fairyglade/ly) is just a mirror. However, you also have to respect the following rules, otherwise your PR may end up being rejected:
+
+## AI usage
+
+While we cannot control your usage of any LLM whatsoever, we do heavily discourage their use for environmental, ethical & moral reasons that you can learn more about on the Internet. However, if you do end up still using them, here are a couple rules you **must absolutely** respect for your PR not to get instantly shot down. Of course, it goes without saying that **all** the other rules in the other sections below **must** be adhered to, even more so when AI is used.
+
+1. **Communicate through you**, not the AI; as in, responses to reviews or other comments in the PR must be written by you and not an LLM. If English isn't your native language and you have a lot of trouble speaking it, you _may_ use AI, but responses must not be your typical, alienating AI-generated text: https://github.com/realrossmanngroup/no_ai_slop_writing_rules
+2. Control the code, as in, **don't vibecode**, especially if you don't know Zig. Don't waste the maintainers's time, and **heavily test your code**, as AI-generated code is typically more error-prone in subtle ways (even if they can be better than humans in some other aspects). Finally, don't generate any "summary" or whatever the AI may come up with during the process. **If you cannot understand the generated code, do not contribute it**. Maintainers are busy and are often simple volunteers, so the less work they have to do, the better.
+3. **Be transparent about AI usage**. Precise what AI model was used in the process, and preferably, how you went about creating your changes (i.e. how did you use AI to make the pull request). The more honest you are about it, the more likely your PR will be accepted and merged into the code base.
+
+If all the above rules are respected, your changes have much more likely to be accepted into the code base.
+
+## Code style
+
+You must follow Zig's [style guide](https://ziglang.org/documentation/master/#Style-Guide). In most cases, all you'll have to do is run `zig fmt` after you have completed your changes, though it does not fix everything, notably variable, function & field naming, as well as the maximum length of aline.
+
+For the former, please refer to the aforementioned style guide in that case. For the latter, you must respect a maximum line length of **80 characters**. For function calls with many parameters or anything similar that may overflow this limit, consider adding a trailing comma to the list so that `zig fmt` can split it into multiple lines. Ideally, few or no lines end up having to get soft wrapped by an editor having this limit set.
+
+## Commit names & descriptions
+
+1. **Commit names must be descriptive**, resorting to the commit description if they are too long. In such cases, the commit name **must** be shortened while still making sense. With that said, no particular convention (emojis, prefixes & suffixes, etc.) is mandated for them, and you are free to adopt any one you think is best or that you are used to.
+2. **Do not force push**, as PRs will get squashed into a single commit anyway. This erases history and makes it impossible to see the changes done over time and by a particular commit.
+3. While not a requirement per se, **consider signing your commits** with an SSH or GPG key for security purposes. This ensures to a lesser extent that you are the person who you claim to be, and reduces the potential amount of malicious contributions that could infiltrate the code base.
+
+## Additional requirements
+
+Other requirements (such as testing your code) for merging the changes will be available when you open your pull request via the template (which you **must** use), however, these are not stated here because they may not be mandatory in some cases (e.g. if the changes are still work-in-progress), so they may temporarily be ommitted for a certain period of time until the changes are fully ready to be reviewed, for instance.

+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 (you must use a **release version** of zig; check that `zig version` does not have a `-dev*` suffix)
+
+  - 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
+
+```
+# dnf install kernel-devel pam-devel libxcb-devel zig xorg-x11-xauth xorg-x11-server brightnessctl
+```
+
+> [!WARNING]
+> Distributions using SELinux such as Fedora and openSUSE Tumbleweed may encounter issues. If you encounter such issues, such as session launch failures, proceed with the following steps:
+>
+> ```
+> # ausearch -m avc -ts recent
+> ```
+>
+> If SELinux is denying process context transition, you will see this output:
+>
+> ```
+> denied { transition } for pid=XXXX comm="ly" path="/usr/bin/bash"
+> scontext=system_u:system_r:unconfined_service_t:s0
+> tcontext=unconfined_u:unconfined_r:unconfined_t:s0
+> tclass=process permissive=0
+> ```
+>
+> Pipe this output into `audit2allow` to generate a security module package. This will persist regardless of changes to filesystem permissions:
+>
+> ```
+> # ausearch -m avc -ts recent | audit2allow -M ly-local
+> ```
+>
+> ```
+> # semodule -i ly-local.pp
+> ```
+>
+> _This fix has been confirmed on Fedora 39 and 44 and openSUSE Tumbleweed. (#494)_
+
+### 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)
+
+## Custom animations & user scripts
+
+If you want to pimp your Ly installation even further than what the traditional configuration file allows you to, a [community repository](https://codeberg.org/fairyglade/ly-community) exists containing custom animations & scripts, so go check it out!
 
 ## 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
-basic wayland support (sway works very well, for example).
+Every environment that works on other login managers also should work on Ly.
 
-## 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 :)
+- Unlike most login managers Ly has an xinitrc and shell entry.
+
+- 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.
+
+- 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.
+
+> [!NOTE]
+> You can, however, test your configuration file changes like that. Note that you must do Ctrl+C in order to exit Ly.
+
+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)
-or a terminal emulator (but desktop environments won't start)
+> [!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:
+
 ```
-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
-disable getty on Ly's tty to prevent "login" from spawning on top of it
+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, Alpine and potentially others, 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 overriding 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.
+
+You can find all the configuration in `/etc/ly/config.ini`. The file is fully commented, and includes the default values.
+
+You may also check the validity of your configuration file (i.e. if there are any errors in it) with the following command:
+
+```
+$ ly --validate-config /etc/ly/config.ini
+```
 
 ## 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:
-```
-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.
-```
-On ArchLinux, the example .xinitrc (/etc/X11/xinit/xinitrc) starts like this:
+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.
+
+## 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:
+
 ```
 #!/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`.
+- The numlock and capslock states are printed in the top-right corner.
 
-## Additional Information
-The name "Ly" is a tribute to the fairy from the game Rayman.
-Ly was tested by oxodao, who is some seriously awesome dude.

+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).
