 My source code for the MMO-programming game: Screeps.
 
 # Status
-To those interested in this code. I wrote the main body of the source code when just learning programming so its kind of a mess. I'm now slowly rewriting the code base to a more SOLID version. :)
+As a way to learn c++ programming I used the screepsxx repo for controlling the screeps with c++.
