Contributing new tutorials or fixes¶

You don’t have to be a developer to participate to theGIMP project.Some team members help with design, community management, bug triaging…and some help with documentation and tutorials!

The only thing we ask of contributors is to useLibre licenses, whichallow anyone to share, redistribute and modify the tutorials. It enablesothers to fix tutorials, even years later, even if the original authoris not around anymore. This is the same rules as for our code, makingGIMP a Free Software.

Recommended licenses are:

• Free Art 1.3
• Creative CommonsAttribution-ShareAlike 4.0 International
• Creative CommonsAttribution 4.0 International
• CC0 1.0 Universal.

So you want to contribute? The process is simple, here is an example forthe hypothetical case where you found an error in an existing tutorial.In such a case of editing existing text, your change will be automaticallyconsidered to be in the same license as chosen by the first author:

1. All tutorial contents can be found on ourwebsite’s repository (Gitlab). After clicking this link, feel free to browse to understand the file structure: Each tutorial is listed in a separate folder and each folder has a file calledindex.md which contains the text of the tutorial. There are many other files that accompany the tutorial inside the folder, such as images, screenshots and various assets.
2. Once you found a tutorial, which you want to edit, click theindex.md link, and you will see a blue button saying “Edit”. Click it (obviously you need to have created a login first and be connected).
3. Gitlab will propose you to “fork” the project because of missing permissions. Press “fork”.
4. Once this is done, make your changes using theMarkdown syntax.
5. When you are happy with your edits, proceed to the bottom of the edit page, notice the “Commit message” field. Fill in relevant information explaining what you did. Click “Commit changes”.
6. A “New merge request” page will appear. Click “Create merge request”.
7. It’s done! Now all you have to do is wait for one of the core members to review and validate your changes.

If you just need to change an image (e.g. because it shows an outdatedversion ofGIMP), you may select the image inGitlab and click the“Replace” button. It will propose you to upload a new version and towrite a “Commit message” to explain the change. Please write down thedesiredLibre license for the image in thecommit message. Then hit “Replace file”.

For more complicated changes, or if you want to propose new tutorials,it might be necessary to understand at least the basics of thegitsource versionning system we use.Alternatively, you may simply write your tutorial in a new text file onyour machine (followingMarkdown syntax), then simplyopen areportand upload all the files (the text file as well as images and otherresources) in this report. Do not forget to tell us the license youchose fromthe list given above.

A list of legacy tutorials can be found here:All (Legacy) Tutorials List

Bear in mind that this list is being provided for legacy reasons only.They were originally made for very old hence outdated versions ofGIMPand most of them do no use Libre licenses allowing editing.
