It's relatively straight forward, and isn't difficult if you dropped the bike in gear. not sure how much harder it is though with luggage attached.
if the bike is in natural and falls on the left, cable tie or something the hand brake in.
whether the bike falls on the left or right, make sure the front end of the frint wheel is pointing in the air. grab the relevant handle near the ground, so you've got the best amount of leverage. bend knees, then straighten back, and walk towards the bike. job done. if the ground is good, it shouldn't be too difficult. you could always practice by lowering the bike on some grass/soft area, or put some padding down.
hope the above helps.
