 ### Configuration
 
@@ -72,37 +74,66 @@ Supysonic looks for two files for its configuration: `/etc/supysonic` and
 Configuration files must respect a structure similar to Windows INI file, with
 `[section]` headers and using a `KEY = VALUE` or `KEY: VALUE` syntax.
 
-Available settings are:
-* Section **base**:
-  * **database_uri**: required, a Storm [database URI][].
-    I personally use SQLite (`sqlite:////var/supysonic/supysonic.db`), but it might not be the brightest idea for large libraries.
-    Note that to use PostgreSQL you'll need *psycopg2* version 2.4 (not 2.5!) or [patch storm](https://bugs.launchpad.net/storm/+bug/1170063).
-  * **scanner_extensions**: space-separated list of file extensions the scanner is restricted to. If omitted, files will be scanned
-    regardless of their extension
-* Section **webapp**
-  * **cache_dir**: path to a cache folder. Mostly used for resized cover art images. Defaults to `<system temp dir>/supysonic`.
-  * **log_file**: path and base name of a rolling log file.
-  * **log_level**: logging level. Possible values are *DEBUG*, *INFO*, *WARNING*, *ERROR* or *CRITICAL*.
-* Section **lastfm**:
-  * **api_key**: Last.FM [API key][api-key] to enable scrobbling
-  * **secret**: Last.FM API secret matching the key.
-* Section **transcoding**: see [Transcoding][]
-* Section **mimetypes**: extension to content-type mappings. Designed to help the system guess types, to help clients relying on
-  the content-type. See [the list of common types][].
-* Section **daemon**
-  * **log_file**: path and base name of a rolling log file.
-  * **log_level**: logging level. Possible values are *DEBUG*, *INFO*, *WARNING*, *ERROR* or *CRITICAL*.

 ### Database initialization
 
 Supysonic does not issue the `CREATE TABLE` commands for the tables it needs.
 Thus the database and tables must be created prior to running the application.
-Table creation scripts are provided in the *schema* folder for SQLite, MySQL
