 A system-wide instance of a repository is created when it is enabled. It is also possible to support both course, and user specific repositories.. This can be achieved by setting the  `enablecourseinstances` and `enableuserinstances` options.  There are three ways that this can be done:
 
 1. Define **$string\['enablecourseinstances'\]** and **$string\['enableuserinstances'\]** in your plugin's language file. You can check an example in the [filesystem repository](https://github.com/moodle/moodle/blob/v4.0.0/repository/filesystem/lang/en/repository_filesystem.php).
-2. The plugin must provide a **get_instance_option_names** method which returns at least one instance option name. This method defined the specific instances options, if none instance atrtribute is needed, the system will not allow the plguin to define course and user instances. Note, you must not define the form fields for these options in the **type_config_form()** function. For example, [filesystem repository](https://github.com/moodle/moodle/blob/v4.0.0/repository/filesystem/lib.php#L439).

 3. Several 'core' repositories use the **db/install.php** to create the original repository instance by constructing an instance of the **repository_type** class.  The options can be defined in the array passed as the second parameter to the constructor. For example [Wikipedia repository](https://github.com/moodle/moodle/blob/v4.0.0/repository/wikimedia/db/install.php).
