You might take a thing or two from the
FIRSTwiki, and host it on Github. Assuming you have little to no pictures, Github works great. Create a quick repository and make a few markdown files. At the end, you can compile it all into a PDF or HTML file to view all at once, but the markdown makes editing a breeze. With pull requests, you can monitor all the incoming edits before they get added.
I don't know anything about WCD, but I'd figured I try and help out with this editing problem.
