+# md5-file [![Build Status](https://travis-ci.org/roryrjb/md5-file.svg?branch=master)](https://travis-ci.org/roryrjb/md5-file) [![js-standard-style](https://img.shields.io/badge/code%20style-standard-brightgreen.svg?style=flat)](https://github.com/feross/standard)
+
+Get the MD5-sum of a given file, with low memory usage, even on huge files.
+
+## Installation
+
+```sh
+npm install --save md5-file
+```
+
+## Usage
+
+### As a module
+```js
+const md5File = require('md5-file')
+
+/* Async usage */
+md5File('LICENSE.md', (err, hash) => {
+  if (err) throw err
+
+  console.log(`The MD5 sum of LICENSE.md is: ${hash}`)
+})
+
+/* Sync usage */
+const hash = md5File.sync('LICENSE.md')
+console.log(`The MD5 sum of LICENSE.md is: ${hash}`)
+```
+
+### As a command line tool
+```
+$ md5-file LICENSE.md
+```
+
+## Promise support
+
+If you require `md5-file/promise` you'll receive an alternative API where all
+functions that takes callbacks are replaced by `Promise`-returning functions.
+
+```js
+const md5File = require('md5-file/promise')
+
+md5File('LICENSE.md').then(hash => {
+  console.log(`The MD5 sum of LICENSE.md is: ${hash}`)
+})
+```
+
+## API
+
+### `md5File(filepath: string, cb: function)`
+
+Asynchronously get the MD5-sum of the file at `filepath`.
+
+The callback `cb` will be called with `(err: Error, hash: string)`.
+
+### `md5File.sync(filepath: string) => string`
+
+Synchronously get the MD5-sum of the file at `filepath`.
