Welcome to the Clowder Project!

The Clowder Project is an online reference work and wiki for category theory and ma­the­ma­ti­cs. It is built using Gerby, created by Pieter Belmans and Raymond Cheng, which is a fork of plas­TeX. The Clowder Project follows the massively collaborative model started by the Stacks Project, and aims to become the equivalent of it for ca­te­go­ry theory.

All comments, no matter how small, are ex­tre­me­ly welcome, as are contributions.

For further notes on the Clowder Project, see the About page.
