+## About
+
+Add-on for BentoBox to calculate island levels for BentoBox game modes like BSkyBlock and AcidIsland. It counts blocks and assigns a value to them. 
+Players gain levels by accumulating points and can lose levels too if their points go down. This add-on will work
 for game modes listed in the config.yml.
 
+Full documentation for Level can be found at [docs.bentobox.world](https://docs.bentobox.world/en/latest/addons/Level/).
+
+Official download releases are at [download.bentobox.world](download.bentobox.world).
+
 ## How to use
 
 1. Place the level addon jar in the addons folder of the BentoBox plugin
