Create a new class for your plugin and use the IPlugin interface from YoYoStudio.Plugins
Create an Initialise (note the UK spelling) method in your class with the return type of PluginConfig
Instantiate the PluginConfig class and provide arguments for _name (the name of your plugin), _description (the description of your plugin), and _required (usually false) and return it at the end of your Initialise method
