If you want to fix a bug or enhance a feature you have two options:
- When you are familiar with Git, go to Tiki project at Gitlab, fork the project and send a merge request.
- When you prefer Subversion (SVN) please get in touch with someone in the community (ex. on IRC) and ask for commit access.
If you do not know how to use Git/SVN or otherwise can't do this at the moment, you can submit your code here on dev.tiki.org as a patch. A patch is a regular tracker item and you can attach your patched file(s). If it's just a few lines, you can also just put the patch in the tracker item using the CODE plugin.
