tome.host draws its basic concept from source-control - a system familiar to computer programmers which allows teams of programmers to work simultaneously on large development projects without overwriting each others work.

There are two areas of content - 'draft', which is the working content that authors make changes to, and 'published', which is the live version that the public actually sees.

The process of publishing essentially copies any changes made to the draft version over to the live public version.
