And from the link, you can click on 'print pdf' to export everything into a single pdf file to be used offline! The pdf file includes contents that used to require downloading of different documents: various user guides, change impact guide, even the technical reference guide (ERD and schema changes)!
You would then want to go to the link under "Advanced Reporting and Database Schema Index" to also download the schema and ERD for PPM, Data Warehouse and Jaspersoft, as well as the PMO guide.
The documents are a lot easier to use now, great work DocOps!
