 Library archives
@@ -23,6 +26,25 @@ The program works with local library archives so download some. In
 addition to the very libraries you need to get INPX indices for them —
 m_Librarian cannot index libraries yet.
 
+Configuration file
+------------------
+
+m_librarian looks up configuration file in $HOME/.config/ (if your OS is
+POSIX-compatible). The configuration file must be named
+``m_librarian.conf``. It must be in ``ini``-file format. The following
+sections and keys are now understood::
+
+    [database]
+    URI = "database URI"
+
+    [library]
+    path = "path to the library archives"
+
+    [download]
+    format = "download file format"
+
+Most programs have an option `-C|--config file` to use a non-default
+configuration file.
 
 Database
 --------
@@ -33,5 +55,24 @@ to use an SQL server you must create a database yourself. For SQLite,
 the database file will be created by the program, so it's the simplest
 way of using m_Librarian.
 
+Database URI
+^^^^^^^^^^^^
+
+In configuration file define section ``[database]`` with the only key
+``URI``. The value for the key must be a Database URI in format accepted
+by SQLObject. Some examples::
+
+   [database]
+   URI = mysql://user:password@host/database
+
+   [database]
+   URI = postgres://user@host/database
+
+   [database]
+   URI = sqlite:///full/path/to/database
+
+See some more examples in m_librarian.conf.sample. See detailed
+description for DB URIs in `SQLObject documentation
+<http://sqlobject.org/SQLObject.html#declaring-a-connection>`_.
