Writing a Lesson

  1. 1

    Pick or propose a topic

    Check the course syllabus for a topic that has no lesson yet, or open an issue to propose a new one, so two people do not write the same lesson.

  2. 2

    Fork the repository

    Fork the site's GitHub repository and create a branch for your change.

  3. 3

    Write the lesson

    Add a Markdown file under src/content/courses/<course>/. Explain one idea, show working code, and finish with a complete code example.

  4. 4

    Open a pull request

    Describe what the lesson covers and which version of the technology it targets. Review comments arrive on the pull request.

Lesson front matter

Each lesson file starts with this block. level is 1 (Beginner) to 4 (Expert), and a value containing ": " must be quoted.
