I have been playing around with the RPI4 and found that under Add/Remove software, that there is a section to download documentation. I installed a few of the packages that I thought would be interesting to read-up on, but I cannot find them anywhere on my pi. I looked online for solutions, but have not managed to find anything on this issue. I checked all of the files on my computer, and even when I run "whereis " it does not say where it is installed on the pi.
I did something like "whereis abs-guide-10-4" in the terminal with no success. Any help would be greatly appreciated.
