-17. Custom column names
+17. Custom column/table names
 
 If your database column name is different than your model attribute, use the
 ``db_column`` parameter. Note that you'll use the field's name, not its column
 name, in API usage.
+
+If your database table name is different than your model name, use the
+``db_table`` Meta attribute. This has no effect on the API used to 
+query the database.
+
+If you need to use a table name for a many-to-many relationship that differs 
+from the default generated name, use the ``db_table`` parameter on the 
+ManyToMany field. This has no effect on the API for querying the database.
