+# Description
 Stratum-mining is a pooled mining protocol. It is a replacement for *getwork* based pooling servers by allowing clients to generate work. The stratum protocol is described [here](http://mining.bitcoin.cz/stratum-mining) in full detail.
 
 This is a implementation of stratum-mining for scrypt based coins. It is compatible with *MPOS* as it complies with the standards of *pushpool*. The end goal is to build on these standards to come up with a more stable solution.
 
-The goal is to make a reliable stratum mining server for scrypt based coins. Over time I will develop this to be more feature rich and very stable. If you would like to see a feature please file a feature request. 
+The goal is to make a reliable stratum mining server for a wide range of coins unlike other forks where the code is limited to specific algorithm's. Over time I will develop this to be more feature rich and very stable. If you would like to see a feature please file a feature request. 
 
 **NOTE:** This fork is still in development. Many features may be broken. Please report any broken features or issues.

 The installation of this *stratum-mining* can be found in the Repo Wiki. 
 
-#Contact
-I am available in the #MPOS, #crypto-expert, #digitalcoin, and #worldcoin channels on freenode. 
-Although i am willing to provide support through IRC please file issues on the repo.
-Issues as a direct result of stratum will be helped with as much as possible
-However issues related to a coin daemon's setup and other non stratum issues, 
-Please research and attempt to debug first.
