+
+## Usage
+
+``` js
+var ram = require('random-access-memory')
+var pause = require('random-access-pause-wrapper')
+var file = pause(ram())
+
+console.log(file.paused) // false
+
+file.write(
+  0,
+  Buffer.from('hello'),
+  function () { // This callback will be triggered on-resume
+    file.write(5, Buffer.from(' world'), function () {
+      file.read(0, 11, console.log) // returns Buffer(hello world)
+    })
+  }
+)
+
+file.pause() // file.paused = true is an alternative API
+console.log(file.paused) // true
+
+file.on('pause', function () { console.log('pause called') })
+file.on('resume', function () { console.log('resume called') })
+file.on('paused', function (paused) { console.log('paused: ' + paused) })
+
+file.resume() // file.paused = false works too.
+```
