This strategy is a work in progress, and everyone can contribute:
Share documentation and organization information with a built in wiki. Each project includes a Wiki rendered by Gollum, and backed by a Git repository.
We are aiming for real time WYSIWYG collaboration (similar to Google Docs) but stored in Markdown and accessible by Git. This should solve the problem of collaborative note taking, be highly approachable for non-technical users, but have the tremendous benefits of storing the content in a portable plain text format that can be cloned, viewed and edited locally (properties of Git).
Next: Simplify wiki editing - Currently wiki editing is inconsistent with every other page, both visually and from a workflow perspective. This makes wiki less approachable for users familiar with the rest of GitLab. We should fix these inconsistencies as a priority.
After: Improve wiki navigation - As wikis grow with more and more content, GitLab is not providing the tools necessary to make them easy to navigate and use. This is a problem that can be resolved with support for macros and a few other small improvements.
We currently most closely compete with GitHub Wikis but we should be competing with:
Due to the current state of Wikis they are not used internally.
