+
+Ultron is a high-intelligence robot. It gathers intelligence so it can start
+improving upon his rudimentary design. It will learn your event emitting
+patterns and find ways to exterminate them. Allowing you to remove only the
+event emitters that **you** assigned and not the ones that your users or
+developers assigned. This can prevent race conditions, memory leaks and even file
+descriptor leaks from ever happening as you won't remove clean up processes.
+
+## Installation
+
+The module is designed to be used in browsers using browserify and in Node.js.
+You can install the module through the public npm registry by running the
+following command in CLI:
+
+```
+npm install --save ultron
+```
+
+## Usage
+
+In all examples we assume that you've required the library as following:
+
+```js
+'use strict';
+
+var Ultron = require('ultron');
+```
+
+Now that we've required the library we can construct our first `Ultron` instance.
+The constructor requires one argument which should be the `EventEmitter`
+instance that we need to operate upon. This can be the `EventEmitter` module
+that ships with Node.js or `EventEmitter3` or anything else as long as it
+follow the same API and internal structure as these 2. So with that in mind we
+can create the instance:
+
+```js
+//
+// For the sake of this example we're going to construct an empty EventEmitter
+//
+var EventEmitter = require('events').EventEmitter; // or require('eventmitter3');
+var events = new EventEmitter();
+
+var ultron = new Ultron(events);
+```
+
+You can now use the following API's from the Ultron instance:
+
+### Ultron.on
+
+Register a new event listener for the given event. It follows the exact same API
+as `EventEmitter.on` but it will return itself instead of returning the
+EventEmitter instance. If you are using EventEmitter3 it also supports the
+context param:
+
+```js
+ultron.on('event-name', handler, { custom: 'function context' });
+```
+
+### Ultron.once
+
+Exactly the same as the [Ultron.on](#ultronon) but it only allows the execution
+once.
+
+### Ultron.remove
+
+This is where all the magic happens and the safe removal starts. This function
+accepts different argument styles:
+
+- No arguments, assume that all events need to be removed so it will work as
+  `removeAllListeners()` API.
+- 1 argument, when it's a string it will be split on ` ` and `,` to create a
+  list of events that need to be cleared.
+- Multiple arguments, we assume that they are all names of events that need to
+  be cleared.
+
+```js
+ultron.remove('foo, bar baz');        // Removes foo, bar and baz.
+ultron.remove('foo', 'bar', 'baz');   // Removes foo, bar and baz.
+ultron.remove();                      // Removes everything.
+```
+
+If you just want to remove a single event listener using a function reference
+you can still use the EventEmitter's `removeListener(event, fn)` API:
+
+```js
+function foo() {}
+
+ulton.on('foo', foo);
+events.removeListener('foo', foo);
+```
