To get started, you need to begin by choosing a name for your module. The module name chosen must be unique and should be all lowercase. The name must only contain letters & numbers whilst always starting with a letter. Underscore is the only accepted special character. For example, valid names would be:

custommodulename OR your_module_name OR your_module

Once you have chosen your name, you need to create a directory and module file for it. Addon modules are found in the /modules/addons/ directory. Each module can be found within it’s own directory /your_module_name/. Then the core module file within it should be “your_module_name.php” to match the folder.

We make available a sample addon module on Github. We recommend using this as a starting point for a custom addon module.
