Improve Documentation

README.md and maybe a website or at least WIKI on how to configure the plugin and how to use it.

Great idea! I would suggest providing some detail on the correct URL format because I pasted it in the API endpoint URL that mini flux hosting shared with me but it had /V1 at the end of it. That led to a 404 error until I figured out that the plug-in needs the base URL and not anything after because it will automatically append the /v1.

Good catch. Yeah, I hope I can add some documentation on the correct setup. I'm glad that it works now :)
