+# FOSS Galaxy Game Library
+
+A library for building FOSS Games, Educational Resources and Academic Experiments.
+
+## Development Instructions
+
+### Building
+It's designed to be a fairly standard cmake project, so the standard cmake steps should work:
+
+```bash
+mkdir build
+cd build
+cmake ..
+make
+```
+
+The library should also build the test scene (`demo`). There is a shellscript in the root of the
+project that will build the project and run the demo project in gdb.
+
+Most of the dependencies should be downloaded automatically. If you're on X don't use glfw from the
+Fedora repos, it won't work (it's configured for Wayland). The version the project builds should work.
+
+### Useful Tools
+The following tools are helpful for development:
+
+* Valgrind (see the ways in which memory is messed up)
+* RenderDoc (see what's being sent to the GPU)
+* GDB (see what caused the crash this time)
+* An Editor/IDE (I'm using neovim with a bit of clion)
