+# Greenlet
+
+> Move an async function into its own thread.
+>
+> A simplified single-function version of [workerize](https://github.com/developit/workerize).
+
+The name is somewhat of a poor choice, but it was [available on npm](https://npm.im/greenlet).
+
+## Installation & Usage
+
+```sh
+npm i -S greenlet
+```
+
+Accepts an async function with, produces a copy of it that runs within a Web Worker.
+
+```
+greenlet(Function) -> Function
+```
+
+
+## Example
+
+```js
+import greenlet from 'greenlet'
+
+let get = greenlet(async url => {
+	let res = await fetch(url)
+	return await res.json()
+})
+
+console.log(await get('/foo'))
+```
