+# Manganelo Plugin
+
+This is the Mango plugin for [Manganelo](https://manganelo.com/). 
+
+Note that
+
+- All downloaded chapters will be placed in their respective series folder in your library.
+- Cloudflare rate limits extensive downloads. Adjust `wait_seconds` in `info.json` if you plan to download many chapters in one go (or chapters with many pages).
+
+Maintained by [@TheBritishAccent](https://github.com/TheBritishAccent).
