Documentation
There is no documentation yet, because there is nothing finished to document. All 139 applications in the catalogue are under development, and reference material written before an application exists has to be rewritten the day it ships.
What it will hold
Listed as intent. None of it is written.
Every screen and every setting in an application, published when that application ships rather than before.
Organizations, branches, people, roles and permissions — the parts that already work and are currently explained on the Features pages.
There is no public API. If one is published, this is where it would be documented.
Every application has a detail page describing what it is for, which category it belongs to and what it would ask of your organization. That is the extent of what is known about them, and it is published in full.
The platform underneath — the part that is built — is explained across the Features pages, with the working capabilities kept visibly apart from the planned ones.
