Potential instructors: please explain subkeys and how it might be best to primarily use subkeys on your computer, tablet etc...

#5 USE IT WELL
...
IMPORTANT:
ACT SWIFTLY IF SOMEONE GETS YOUR PRIVATE KEY
If you lose your private key or someone else gets ahold of it (say, by stealing or cracking your computer), it's important to revoke it immediately before someone else uses it to read your encrypted email. This guide doesn't cover how to revoke a key, but you can follow the instructions on the GnuPG site. After you're done revoking, send an email to everyone with whom you usually use your key to make sure they know.
The text links to https://www.gnupg.org/gph/en/manual.html#AEN305


If I were to use the instructions and followed the link, I would say, what are subkeys?  And have no clue about keeping which keys or subkeys where...

Proper training should include the processes to recover a loss of a private subkey without losing all your key signings.

The best HowTo on subkeys I have seen, but not really noob-friendly if you want to avoid the command line:
