nLab software

The software underlying the nLab is a heavily modified fork of Instiki. The code is moving further and further away from the original Instiki, and the plan (hopefully by the end of 2019) is to have evolved to what is essentially an entirely distinct codebase, no longer a fork.

Local development

The nLab is currently not well suited to developing locally. This will change with the move to a distinct codebase. If you are interested in working on something, get in touch with Richard Williamson, who will be happy to suggest tasks or provide suggestions for how to work locally on something.

Joining in

All help is very welcome! Just get in touch on the nForum to express your interest, and we'll take it from there.
