-# screeps
-My source code for the MMO-programming game: Screeps.
+# Douwco Hivemind
+This is the sourcecode of my hivemind implementation for the MMO-programming game Screeps. This is mainly designed to learn programming with C++. This is possible throught the work done in the screepxx project, which I will and try to expand as well. 
 
-# 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. :)
+# Running the project
+All commands are run starting from the root directory.
+
+## Emsdk setup
+Screeps only supports ES5 js syntax which can only be guaranteed by using emsdk 2.0.0.
+
+```
+cd emsdk && \
+./emsdk install 2.0.0 && \
+./emsdk activate 2.0.0 && \
+source ./emsdk_env.sh && \
+cd ..
+```
+
+## Cmake setup
+Create the makefiles using cmake. For more info look at the readme in screepsxx.
+
+```
+mkdir build
+cd build
+cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=emsdk/upstream/emscripten/cmake/Modules/Platform/Emscripten.cmake ..
+```
+
+# Build
+To build the project run the following. In the dist folder the "screeps ready" project is copied.
+
+```
+cd build
+cmake --build .
+```
