Together with Johan Henriksson in Cambridge, I develop a modular hardware documentation software called DocuBricks (free-and-open-source of course!) and a repository: http://docubricks.com/. There will be a workshop session on Saturday on it, as well. In the run-up for GOSH '17, we are looking for volunteer web-developers who are keen to help making Open Hardware documentation easier and better, by contributing to the DocuBricks infrastructure.
solved: We were looking for urgent help for the front end to view the existing documentation structure nicely in a browser and print. This has been solved and closed thanks to the team!
Nevertheless, further team members are always welcome, especially individuals keen to develop the website services further.
