-**To-do List**
-1. Fix memory leak of /reloadredis (Not yet known how to fix it, it can be easily noticed by changing IP addresses and using NetworkInterceptor plugin, it'll show connections still being done to old IP address, aswell as the new one, even if it doesn't use old IP address for anything.)

 RediSkript allows you to communicate between your servers with use of Redis, it's very fast and easy to use.
 
 You can transfer any data in the form of text between your servers, you can program it to execute a set of instructions on the server depending on the redis message, etc. This can be used for making scripts that sync data between all servers and much more!
 
 
 It is originally developed by the team of Govindas Limework developers and is now maintained only by Govindas.
-Example:

+Redis Message:
 ```

+send "%{test::*}%" #outputs 100, 100 and 100
 
-and that's all there is to this addon! You only need to have matching configuration in every server for communication and a Redis server to connect to. I recommend using VPS for hosting redis server, I personally use VPS from humbleservers.com.

+Syntax:
