Other information that applies to all types of plugins:

• Where to put language strings for your plugin
• Defining the database tables for your plugin

Please see the Guidelines for contributed code for an overview of how to contribute to the Moodle code.

Sometimes it is not possible to write a proper plugin for what you want to do, in which case you may have to resort to using the local customisations hook.
