Frequently asked questions

Are these tutorials free?

Yes — every tutorial is completely free. We write them to share what we learn shipping production code at PAROT.

How often do you publish new tutorials?

We aim to publish 2-3 new tutorials per month, covering whatever tools or patterns our engineering team is actively using.

Can I request a topic?

Absolutely. Drop us a message through our Contact page and we'll add it to our editorial backlog. Popular requests get prioritised.

What skill level do I need?

We tag each tutorial with a difficulty level — Beginner, Intermediate, or Advanced. Most of our content assumes basic familiarity with JavaScript and the command line.

Do you offer workshops or live sessions?

Not yet, but it's on our roadmap. Subscribe to our updates to be notified when we launch workshops.
