+
+The goal of QCGPU is to provide a library for the simulation of 
+quantum computers that is fast, efficient and portable.
+
+QCGPU is written in Rust and uses OpenCL to run code on the CPU, GPU or any other OpenCL supported devices.
+This library is meant to be used both independently and alongside 
+established tools for example compilers or more general and high level frameworks.
+If you are interested in using QCGPU with IBM's [QISKit](http://qiskit.org/) 
+framework or [QISKit ACQUA](https://qiskit.org/acqua/), please see 
+the repository [qiskit-addon-qcgpu](https://github.com/qcgpu/qiskit-addon-qcgpu).
+
+## Prerequisites
+
+To use this library, you will need two things:
+
+* OpenCL (Ensure that an OpenCL library is installed for your platform and that `clinfo` or some other diagnostic command will run).
+* Rust (install [here](https://www.rustup.rs)). Please use a nightly build.
+
+## Usage
+
+First, add the crate to `cargo.toml`
+
+```toml
+[dependencies]
+qcgpu = { git = "https://github.com/QCGPU/QCGPU-rust" }
+```
+
+Then use the crate!
+
+```rust
+extern crate qcgpu;
+use qcgpu::State;
+
+fn main() {
+    let mut state = State::new(2, 0).unwrap();
+    state.x(0);
+
+    println!("Measured: {}", state.measure().unwrap());
+    // 1
+}
+```
