If you are new to coding, start with IDEs, then move on to HTML. The ready tracks are listed in the order they build on each other: IDEs, HTML, CSS, JavaScript, then Python. If you already know the basics, jump straight to the track you need.

No. You can open any lesson from the sidebar at any time. Lessons inside a track do build on each other, though, so going in order is the easiest way to learn a topic that is new to you.

Some lessons end with a quiz or an exercise. The Next Lesson button unlocks once you answer the quiz correctly or finish the exercise, so you know the idea stuck before you build on it. You can still reach any lesson from the sidebar.

That track is planned, but its lessons are not written yet. You can open it now to see a short introduction page, and the full lessons will take its place once they are ready.

A track teaches one language or tool from start to finish, like HTML or CSS. A guided path is built around a project instead: it picks lessons from several tracks, in order, so you finish with one working thing, like a todo app. Browse the guided paths
