XOD is a flow-based programming language as opposed to more popular imperative languages. That means some things are much easier to do in XOD, but other things are not so obvious. Particularly, for a newcomer, it could be hard to understand how to control the order of execution: do a thing first, then another thing, and only after that do the third.

We described one possible solution to do jobs in a sequence in the new guide article: 🚦 [Simple Traffic Light Example](https://xod.io/docs/guide/simple-traffic-light/). Hope you will find it useful. Feel free to ask questions, and [make changes to the article](https://github.com/xodio/xod/blob/master/docs/guide/simple-traffic-light/README.md) if you can make it better.
