[#2] Added Licensing.

I decided on the Apache-2.0 license and have stamped all the files to
now point to that license.

 # Sigils #
-A mathematics library.
+**sigils** is a trait-driven Rust math library offering vector, quaternion, and 
+numeric abstractions for simulation, graphics, and systems-level development.
+
+It focuses on performance, generic correctness, and ergonomic APIs without 
+sacrificing type safety or precision.
+
+---
+
+## Features
+
+- Generic `Vector` and `Quaternion` trait abstractions
+- Implementation of common 2D and 3D types (`Vec2`, `Vec3`, `Quat`)
+- Traits for scalar math operations on floats and integers
+- Designed for zero-cost abstractions and compiler optimization
+- Suited for simulation, embedded graphics, and procedural tools
+
+---
+
+## Motivation
+
+Simulation, game, and physics systems often need mathematical primitives with
+predictable behavior, performance, and strong type guarantees.
+
+**sigils** exists to provide just that, core math abstractions without the
+complexity or bloat of large game engines or math suites.
+
+---
+
+## Getting Started
+
+First, add the CyberMages registry to your Cargo config:
+
+```toml
+[registries.cybermages]
+index = "sparse+https://workshop.cybermages.tech/api/packages/CyberMages/cargo/"
+```
+
+Then add `sigils` to your dependencies:
+
+```toml
+[dependencies]
+sigils = { version = "0.1", registry = "cybermages" }
+```
+
+---
+
+## Example Usage
+
+```rust
+TODO: Rotate a Vector with a Quaternion.
+```
+
+---
+
+## Documentation
+
+Documentation can be generated locally with:
+
+```bash
+cargo doc --open
+```
+
+---
+
+## Design Highlights
+
+- Uses traits to decouple math concepts from specific types
+- Scalar math via trait constraints allows use of `f32`, `f64`, or custom types
+- Encourages composability across simulation and rendering domains
+- Small and dependency-free core, easy to embed or extend
+
+## Notes
 
 The code in this library uses macros pretty heavily. As such,
 please check the trait's documentation for a function since the
 macro definition will not really be documented. This was not
 done to make documentation difficult, but to make coding the
 library easier and to make it easier to maintain.
