 MMMCalc
 =======
 
-This is a very simple project, it was made for educational purposes (hence why it is open-source), and I encourage everyone to contribute if they have something to add.
+### Compiling
+MMMCalc uses [CMake](http://cmake.org/) to compile. Please install the C development tools and CMake (along with whichever build script you plan on having CMake generate) in order to run this command.
+```bash
+$ cd build/
+$ cmake ..
+$ make
+```
 
-The most simple way to build this project is to move to the src folder/directory and run
+### Contributing
+To contribute, simply open a pull request, however, be aware that this code is licensed under a GNU GPLv3 and so will yours.
 
-	$ javac MMMCalc.java
-
-This will allow you to build the project that should work properly if you are downloading one of the releases (if you download the straight from the master branch it might have some problems).

-To contact me, send me an e-mail at <nicolas.ortega.froysa@gmail.com>.
