And that’s were you come in! If you are an advanced user it we need you to update old sections or write explanations of new features. But even if you have the feeling you are not experienced enough to write something, you can still update screenshots! If you benefit from the work others did on Kdenlive it is a great (and easy) opportunity to give something back to the project and the community!

To edit a wiki page you need a KDE Identity / MyKDE Account.
The new Kdenlive Manual (moved from the [https://userbase.kde.org/Kdenlive/Manual wiki] in November 2021 to [https://docs.kdenlive.org docs.kdenlive.org]) is based on [https://www.sphinx-doc.org Sphinx] and lives in a [https://invent.kde.org/documentation/docs-kdenlive-org git repository].

Kdenlive is a powerful tool with a lot of features but all the different menu entries, buttons and shortcuts can be sometimes confusing. The User Manual is important for beginners as well as advanced users searching for a specific feature. However maintaining the manual is a big task the small Kdenlive Core Team can't handle alone...

And that’s were you come in! If you are an advanced user it we need you to update old sections or write explanations of new features. But even if you have the feeling you are not experienced enough to write something, you can still update screenshots! If you benefit from the work others did on Kdenlive it is a great (and easy) opportunity to give something back to the project and the community!

Join the Kdenlive Main Matrix Room to get in touch.
