 # Eye of Nemesis
 Eye of Nemesis is a plugin that allows server admins to write policies that will deny or allow (black/whitelist) players to do specific things based on the value of nodes.
 
-## Warnings
-- This plugin is in a very early stage.
-- Even though running `/eye` will tell you to run `/eye help` to list all available commands, this is not implemented yet, however all commands are available as tab-complete of `/eye`.
-
 ## Motivations
 I made this plugin as an effort to preserve a village from my private server. Originally from beta 1.7.3 Betalands server, then transferred to RetroMC, and then finally we downloaded the chunks to merge into our server, I was afraid it would not have the same feeling after all the updates, so I had the idea to make a plugin that can block the newer features.
