Step by step instructions

[BWMerlin]

The current install document (IMO) is woeful. It basically amounts to "install the programme and it works" with no real details given on how to actually install GLPI or it's dependencies.

When trying to figure out how to install GLPI (the guides on the GLPI site are all years out of date) I found two great websites both of which contain some small errors/out of date version numbers but where enough to get me going.
https://computingforgeeks.com/how-to-install-glpi-on-ubuntu-linux/
https://www.osradar.com/how-to-install-glpi-on-ubuntu-20-04/

Would anyone mind if I write step by step documentation (it will be based on the above two links and corrected for current version numbers and other minor errors the other guides contain) on how to install GLPI on Ubuntu as part of the install instructions?
