Sure, I can elaborate. The article assumed a little bit of familiarity with Zapier. The basic mechanics are creating a new Zap on Zapier (which is a pair of one trigger and one action).

For the trigger, choose "GTalk" and "New Message". Specifically, the Zap will trigger whenever you send a message to our always-on bot.

You can pick any action that suites you, see the article for ideas.

We'll automatically perform the action whenever the trigger occurs.

There is a lot of flexibility in the system but that's the 500 foot view.
