For a config I what a config named Tags.hmm how would I register that and would I need to add it under resources
please try to rephrase that, because I can't make much sense out of our mix of words (a sentence would be helpful!) if you are not a native english speaker, or just bad at it try to explain yourself as detailed as possible.
You need to put your config in the resources/ folder. See how I do it on my KillMoney plugin (Line 33 to Line 36) - that only works for the config.yml, otherwise you can create your own saveDefaultConfig() as seen on PluginBase
