+> Zero CPU overhead, zero dependency, true event-loop blocking sleep
+
+## Usage
+
+```js
+const sleep = require('atomic-sleep')
+
+console.time('sleep')
+setTimeout(() => { console.timeEnd('sleep') }, 100) 
+sleep(1000)
+```
+
+The `console.time` will report a time of just over 1000ms despite the `setTimeout`
+being 100ms. This is because the event loop is paused for 1000ms and the setTimeout
+fires immediately after the event loop is no longer blocked (as more than 100ms have passed).
+
+## Install
+
+```sh
+npm install
+```
+
+## Run tests
+
+```sh
+npm test
+```
+
+## Support
+
+Node and Browser versions that support both `SharedArrayBuffer` and `Atomics` will have (virtually) zero CPU overhead sleep. 
+
+For Node, Atomic Sleep can provide zero CPU overhead sleep from Node 8 and up.
+
+For browser support see https://caniuse.com/#feat=sharedarraybuffer and https://caniuse.com/#feat=mdn-javascript_builtins_atomics.
+
+
+For older Node versions and olders browsers we fall back to blocking the event loop in a way that will cause a CPU spike.
