+# Ly - a TUI display manager
+[![CodeFactor](https://www.codefactor.io/repository/github/cylgom/ly/badge/master)](https://www.codefactor.io/repository/github/cylgom/ly/overview/master)
+![Ly screenshot](https://user-images.githubusercontent.com/5473047/42466218-8cb53d3c-83ae-11e8-8e53-bae3669f959c.png "Ly screenshot")
+
+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
+ - make
+ - pam
+ - xcb
+ - xorg
+ - xorg-xauth
+ - mcookie
+ - tput
+ - shutdown
+
+## Support
+The following desktop environments were tested with success
+ - budgie
+ - cinnamon
+ - deepin
+ - enlightenment
+ - gnome
+ - i3
+ - kde
+ - lxde
+ - lxqt
+ - mate
+ - sway
+ - xfce
+ - pantheon
+
+Ly should work with any X desktop environment, and provides
+basic wayland support (sway works very well, for example).
+
+## 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 :)
+
+## Cloning and Compiling
+Clone the repository
+```
+git clone https://github.com/cylgom/ly.git
+```
+
+Fetch submodules
+```
+make github
+```
+
+Compile
+```
+make
+```
+
+Test in the configured tty (tty2 by default)
+or a terminal emulator (but desktop environments won't start)
+```
+sudo make run
+```
+
+Install Ly and the provided systemd service file
+```
+sudo make install
+```
+
+Enable the service
+```
+sudo 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
+```
+sudo systemctl disable getty@tty2.service
+```
+
+## Configuration
+You can find all the configuration in `/etc/ly/config.ini`.
+The file is 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).
+
+## 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`.
+
+## 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.
