Could not load plugin

I'm using BETA 4.0.0

[21:55:44 ERROR]: Could not load 'plugins\ImprovedFactions-BETAv4.0.0.jar' in folder 'plugins'
org.bukkit.plugin.UnknownDependencyException: Unknown/missing dependency plugins: [ProtocolLib]. Please download and install these plugins to run 'ImprovedFactions'.

Steps to replicate:

1. Place the plugin on the /plugin path
2. Run the server
3. The error will be prompted and the plugin will not be available in game

Did you install protocolLib?

My bad, installed ProtocolLib and now it's working!
