+# GFX Maths
+This crate implements all the basic mathematical structures and operations
+that are needed for almost any graphical program, namely:
+- [Vec2](src/vec2.rs)
+- [Vec3](src/vec3.rs)
+- [Vec4](src/vec4.rs)
+- [Quaternion](src/quaternion.rs)
+- [Mat4](src/mat4.rs)
+
+The usual operations are implemented via member functions and operator overloads.
+Operators should handle almost exactly as they would in GLSL, e.g.
+```Rust
+use gfx_maths_rs::*;
+
+let v = Vec3::new(5.0, 6.0, 7.0);
+let s = 1.0 / v;
+
+let t = Mat4::translate(Vec3::new(1.0, 0.0, 0.0)) * s;
+```
+
+# Notation
+Vectors are always treated as column vectors, which is why
+only [Mat4](src/mat4.rs) * [Vec4](src/vec4.rs) is implemented and not [Vec4](src/vec4.rs) * [Mat4](src/mat4.rs).
