• If you want to know how to send message, see Message If you want to knwo how to get contact, see Contact
  should be two lines

• wechaty.on(event, listener) section, Returns: Wechaty -- this is for chain.
  better to have an example to show how to chain.

• Example code section's title should explains a little what this example does, or at least tell the user that is the example for.

• wechaty.init() is deprecated, we should tell user which one to replace this. Maybe add use start instead.

• wechaty.start() Maybe we could reminds the user that most of the bot operation needs to be triggered after start() is done

• instance example is still using init(), should be replaced by start()

Method chaining, also known as named parameter idiom, is a common syntax for invoking multiple method calls in object-oriented programming languages. Each method returns an object, allowing the calls to be chained together in a single statement without requiring variables to store the intermediate results. [More info](https://en.wikipedia.org/wiki/Method_chaining)

`Wechaty` class support method chaining, you could write code like this:
``
const { Wechaty } = require('wechaty')
const bot = new Wechaty()
.on('scan', (qrcode, status) =>  {})
.on('login', user => {})
.on('message', message => {})
.start()
``
