+This project was made for Linux using SDL and OpenGl. It is up to you to
+satisfy these dependencies. A port for Windows and/or Mac may be considered in
+the future.
+
+Currently only an in-place 'install' is possible; why would you want more for a
+simple physics simulator?
+
+
+To build the project change into the src directory and run make. i.e.
+
+cd src/
+make
+
+This will create the run_physics file located in this directory. Simply execute
+this file to run the program. i.e.
+
+./run_physics
