At the end of some chapters, I will list resources you can use to explore additional concepts relative to the content of the chapter. While not required, you should definitely explore them as these resources will go over additional content that didn't fit the scope of the chapter but are still useful for expanding your knowledge even further:
- Ubuntu installation documentation: https://help.ubuntu.com/community/Installation
- Etcher user documentation: https://github.com/resin-io/etcher/blob/master/docs/USER-DOCUMENTATION.md
