 ## Usage
 
-Create a class extending `Entities` and implement the `getMap()` method. By default, the table
-name will be inferred from the class name, and all mapped columns in this table will be selected.
-
-To join other tables and alter output values, implement the `getBaseQuery()` and `getSelectProps()` methods.
+Create a class extending `Entities`, and implement the methods to map properties to columns and
+define the base SQL query (see example below).
 Pass the callable returned by the route handling functions to your Slim or other PSR-7 compatible framework.
