 A slick-looking LightDM greeter.
 
+Features:
+- Slick-Greeter is cross-distribution and should work pretty much anywhere.
+- All panel applets are embedded. No external indicators are launched or loaded
+  by the greeter.
+- No settings daemon are launched or loaded by the greeter.
+- This greeter supports HiDPI.
+- Sessions are validated. If a default/chosen session isn't present on the
+  system, the greeter scans for known sessions in /usr/share/xsessions and
+  replaces the invalid session choice with a valid session.
+- You can take a screenshot by pressing PrintScrn. The screenshot is saved in
+  /var/lib/lightdm/Screenshot.png.
+- The default configuration is stored in dconf under the schema
+  x.dm.slick-greeter.
+- Users can create and modify /etc/lightdm/slick-greeter.conf, settings in this
+  files take priority and overwrite dconf settings.
