As said in the title: we need documentation.
We need documentation, but also note that this process of building and releasing iOS apps is still in a flux. I have discussed further automatisation with Brendan.
The keyboard apps and the Divvun installer (win/mac) is built using CI/CD on Azure by the TTC. They will also document the setup, and how to add new apps and new projects to the CI/CD system.
I will keep this open until the documentation for the new build system is accepted.
