Editing the website - t-oster/VisiCut GitHub Wiki
Website
Note: This information concerns the new website http://t-oster.github.io/VisiCut/ , and not the old website http://hci.rwth-aachen.de/visicut .
The website visicut.org is hosted via github pages. Whoever wants to contribute, just create pull-requests on the branch "gh-pages".
I would recommend to clone this into a new repository, since it has nothing in common with the master branch used for VisiCut development:
git clone https://github.com/t-oster/VisiCut.git -b gh-pages --single-branch VisiCutPage
(for write access, replace the URL by your forked git-url).
Wiki
The Wiki https://github.com/t-oster/VisiCut/wiki/ can be directly edited with the "Edit" button on every page.
