How to modify the documentation?

That seems - more or less - as the correct thing to do. Specifically:

  1. Create an account on invent.kde.org
  2. Fork the project develop-kde-org with your account.
  3. Clone the resulting fork, which will be a repository you own.
  4. Run the testing setup as documented in the README.
  5. Fix the documentation and test locally.
  6. Commit and push your changes.
  7. Go to your project on invent.kde.org and and submit a merge request.

Good luck!
