+A new plugin can be created by implementing the methods from interface and exporting a symbol with `Generator` as the name and the plugin struct as the type. The `GetName()` function returns the name that is used for looking up the corresponding template set in your config file. It can also be included in the templated files with the default plugins using the `{{ plugin_name }}` in your template. The `GetVersion()` and `GetDescription()` functions returns the version and description of the plugin which can be included in the templated files using `{{ plugin_version }}` and `{{ plugin_description }}` respectively with the default plugins. The `Generate` function is where the magic happens to build the config file from a template.
