+## Usage
+
+### Check out our [online demo](https://rustpython.github.io/demo/) running on WebAssembly.
+
+## Goals
+
+-   Full Python-3 environment entirely in Rust (not CPython bindings)
+-   A clean implementation without compatibility hacks
+
+## Quick Documentation
+
+```js
+pyEval(code, options);
+```
+
+`code`: `string`: The Python code to run
+
+`options`:
+
+-   `vars`: `{ [key: string]: any }`: Variables passed to the VM that can be
+    accessed in Python with the variable `js_vars`. Functions do work, and
+    recieve the Python kwargs as the `this` argument.
+-   `print`: `(out: string) => void`: A function to replace the native print
+    function, by default `console.log`.
