+
+> [Debounce](https://davidwalsh.name/javascript-debounce-function) a function
+
+## Install
+
+```
+$ npm install debounce-fn
+```
+
+## Usage
+
+```js
+const debounceFn = require('debounce-fn');
+
+window.onresize = debounceFn(() => {
+	// Do something on window resize
+}, {wait: 100});
+```
+
+## API
+
+### debounceFn(input, options?)
+
+Returns a debounced function that delays calling the `input` function until after `wait` milliseconds have elapsed since the last time the debounced function was called.
+
+It comes with a `.cancel()` method to cancel any scheduled `input` function calls.
+
+#### input
+
+Type: `Function`
+
+Function to debounce.
+
+#### options
+
+Type: `object`
+
+##### wait
+
+Type: `number`\
+Default: `0`
+
+Time to wait until the `input` function is called.
+
+##### before
+
+Type: `boolean`\
+Default: `false`
+
+Trigger the function on the leading edge of the `wait` interval.
