not really sure what specific info you need, but the gist is - small ring in front, big ring behind - light pedalling, slow, used for uphill - big ring in front, small ring behind - hard pedaling, fast, used for flat, downhill by big/small i don't mean the big ring and small ring themselves, but the tooth count on the rings.
when shifting up or down, ease the pressure on the pedal - engagement will be quicker, less clicking noises regardless of the groupset and it'll be easier on the drivetrain
prep before going uphill - refrain from shifting while under load. i've experienced chain snapping in the middle of a climb. i shifted while standing in a climb by 3 gears (from memory). i wasn't prepped when i approached the climb.
in spite of the readings you'll do, nothing replaced actual practice. it took me a bit of time before getting used to gears back then (3x8).
btw, i'm lazy in shifting and i hate hb clutter so i switched to 1x
