 # nMage
 
-## GLSL Linter
+nMage is a (hopefully!) high performance 3D Game Engine written in Go being developed [live](https://twitch.tv/bloeys), with recording posted on [YouTube](https://www.youtube.com/channel/UCCf4qyNGPVwpj1HYFGahs_A).
 
-For the linter to work shaders must be `*.vert, *.frag etc...` or `*.vert.glsl, *.frag.glsl etc...`.
+This project is being built with the goals being (in no particular order):
+
+* Sharing knowledge about less popular/less taught (e.g. compared to web dev), yet very powerful computing topics by building things and explaining as we go
+* Showing the development process of large, high performance software, including things like: learning unfamiliar topics, reading docs, fixing bugs and profiling and optimizing
+* To build a good game engine that can actually be used to develop games
+* Have fun through the entire thing!
+
+## Running the code
+
+To run the project you need:
+
+* A recent version of [Go](https://golang.org/) installed
+* A C/C++ compiler installed and in your path
+  * Windows: [MingW](https://www.mingw-w64.org/downloads/#mingw-builds) or similar
+  * Mac/Linux: Should be installed by default, but if not try [GCC](https://gcc.gnu.org/) or [Clang](https://releases.llvm.org/download.html)
+
+Then simply clone and use `go run .`
+
+> Note: that it might take a while to run the first time because of downloading/compiling dependencies.
