+## Geometry Wars Clone
+
+This is a Geometry Wars clone by Raul Roa.
+
+If you want to build this code on linux you first need to install the following libraries:
+* OpenGL
+* GLU
+* SDL
+* SDL Mixer (for playing audio)
+
+If you are using Ubuntu you can install these libraries by typing the following command:
+```
+sudo apt-get install build-essential libgl1-mesa-dev  libsdl-mixer1.2-dev
+
+```
+
+Then , finally , build the code by running the following command
+```
+make linux
+```
