-====================
+# SpaceShipSim
+
 This is a small simulation program of a space ship (with infinite fuel) in a
 frictionless environment (space). The idea is to use it for educational
 purposes.
 
-# Compiling
------------
+## Compiling
+
 In order to build this program you will require the following dependencies:
 
- - GNU GCC (https://gcc.gnu.org/)
- - CMake (https://cmake.org/)
- - Allegro 5 (http://liballeg.org/)
+- A C compiler that supports C99 or higher
+- CMake 3.10 or higher
+- Allegro 5
 
 You can then compile the program via the following commands:
 
+```bash
 cd build/
 cmake ..
 make
+```
 
 This will create a release build with compiler optimizations. If you would like
-a debug build then pass the `-DCMAKE_BUILD_TYPE=debug' flag to the `cmake'
-command. If you would like to install then run `cmake' with the additional flag
-`-DCMAKE_INSTALL_PREFIX=<install_dir>'. If you are installing as a user then
-you may want to set the installation prefix to `/usr/local/', and if you're
+a debug build then pass the `-DCMAKE_BUILD_TYPE=debug` flag to the `cmake`
+command. If you would like to install then run `cmake` with the additional flag
+`-DCMAKE_INSTALL_PREFIX=<install_dir>`. If you are installing as a user then
+you may want to set the installation prefix to `/usr/local/`, and if you're
 packaging then please consult your distribution's policies. With this you
 should be able to run the `make install' target and install the binary.
