-# PacketEvents
-Listen to minecraft packets and send minecraft packets.
+# packetevents by retrooper
 
-Credit to TinyProtocol
+A lightweight spigot packetlistener & packetsender coded by retrooper.
 
-PacketEvents coded by purplex.
+## Credit:
 
-Coding help discord server: https://discord.gg/ZWTkg4v
+PacketEvents uses a modified version of [TinyProtocol](http://github.com/dmulloy2/ProtocolLib/blob/master/TinyProtocol/src/main/java/com/comphenix/tinyprotocol/TinyProtocol.java) by [@DeprecatedLuke](https://github.com/DeprecatedLuke) to support 1.7.10 & 1.8.
+I modified DeprecatedLuke's version of TinyProtocol and added support for 1.9+ versions.
 
-Examples can be found at
-me/purplex/packetevents/example/TestExample.java
+PacketEvents also took Atlas' Packet class.(all the packet names)
