Technical Documentation

Technical documentation is about describing how your system, code, or prototype works so that others can use, maintain, or extend it. It often includes setup instructions, code comments, API descriptions, hardware schematics, or troubleshooting guides. For example, when you build an Arduino-based prototype, your technical documentation might include a wiring diagram, the Arduino sketch with clear comments, and a short guide on how to install necessary libraries.

Why is this relevant to you? Because technical documentation ensures that your work is reproducible. It allows teammates, teachers, or future developers to understand and continue your project without starting from scratch. In professional practice, technical documentation is essential for collaboration, handover, and long-term sustainability of products and systems.

Starting Points

  • Document how to set up and run your project (e.g., installation steps, dependencies).
  • Add comments in your code that explain the why, not just the what.
  • Use version control platforms like GitHub or GitLab to combine code with clear README files.
  • Include diagrams (wiring, architecture, workflows) to clarify complex setups.

Key Points

  • You write documentation that someone with basic technical skills can follow.
  • You keep your documentation up to date with changes in the code or prototype.
  • You balance detail and clarity: provide enough information without overwhelming the reader.
  • You test your documentation by asking a peer to follow it and provide feedback.
