@@ -14,3 +14,43 @@ Key features of LightDM are:
 - Guest sessions.
 - Supports remote login (incoming - XDMCP, VNC, outgoing - XDMCP, pluggable).
 - Comprehensive test suite.
+
+Releases are synchronised with the [Ubuntu release schedule](https://wiki.ubuntu.com/Releases) and supported for the duration of each Ubuntu release. Each release is announced on the [mailing list](http://lists.freedesktop.org/mailman/listinfo/lightdm).
+
+The core LightDM project does not provide any greeter with it and you should install a greeter appropriate to your system. Popular greeter projects are:
+
+ * [LightDM GTK+ Greeter](https://launchpad.net/lightdm-gtk-greeter) - a greeter that has moderate requirements (GTK+).
+ * [LightDM KDE](http://projects.kde.org/lightdm) - greeter used in [KDE](http://kde.org) (Qt)
+ * [LXqt Greeter](https://github.com/lxde/lxqt-lightdm-greeter) - greeter used in [LXqt](http://lxqt.org/) (Qt)
+ * [Pantheon Greeter](https://launchpad.net/pantheon-greeter) - greeter used in [Elementary OS](http://elementaryos.org/) (GTK+/Clutter).
+ * [Unity Greeter](https://launchpad.net/unity-greeter) - greeter used in [Unity](https://launchpad.net/unity).
+ * [WebKit2 Greeter](https://github.com/antergos/lightdm-webkit2-greeter) - greeter that can be themed using HTML/CSS/Javascript
+ * Run with no greeter (automatic login only)
+ * [Write your own...](https://www.freedesktop.org/wiki/Software/LightDM/Development/)

+# Configuration
+
+LightDM configuration is provided by the following files:
+
+```
+/usr/share/lightdm/lightdm.conf.d/*.conf
+/etc/lightdm/lightdm.conf.d/*.conf
+/etc/lightdm/lightdm.conf
+```
+
+System provided configuration should be stored in `/usr/share/lightdm/lightdm.conf.d/`. System administrators can override this configuration by adding files to `/etc/lightdm/lightdm.conf.d/` and `/etc/lightdm/lightdm.conf`. Files are read in the above order and combined together to make the LightDM configuration.
+
+For example, if a sysadmind wanted to override the system configured default session (provided in `/usr/share/lightdm/lightdm.conf.d`) they should make a file `/etc/lightdm/lightdm.conf.d/50-myconfig.conf` with the following:
+
+```
+[Seat:*]
+user-session=mysession
+```
+
+Configuration is in keyfile format. For most installations you will want to change the keys in the `[Seat:*]` section as this applies to all seats on the system (normally just one). A configuration file showing all the possible keys is provided in [`data/lightdm.conf`](https://github.com/CanonicalLtd/lightdm/blob/master/data/lightdm.conf).
