Hi,
I managed to migrate the whole User Guide to AsciiDoctor and you can check
it out on this branch:
https://github.com/vladmihalcea/hibernate-orm/tree/feature/asciidocs
Next week, I'll start reading and reviewing it, and make a plan of what
needs to be written so we have a full 5.0 user reference documentation.
Have a great week-end,
Vlad
