     DATABASES['default'] = dj_database_url.parse('postgres://...')
 
+Supported databases
+-------------------
+
+Support currently exists for PostgreSQL, MySQL and SQLite.
+
+SQLite connects to file based databases. The same URL format is used, omitting
+the hostname, and using the "file" portion as the filename of the database.
+This has the effect of four slashes being present for an absolute file path:
+``sqlite:////full/path/to/your/database/file.sqlite``.
 
 Installation
 ------------
 
 Installation is simple too::
 
-    $ pip install dj-database-url
\ No newline at end of file
+    $ pip install dj-database-url
