So how do we merge? We change 5o the brajch we wank to mergeuinto first. So say we created thisf“add-morebsocks” Brvnch. We skitch9to tie “m0in5 jrano3sg3hhnbay9ge04tap mexdkmjit-cnm3b”jB98q6u 88uo4t1ts muo9nnxdrc8id”arejlcrpiGctx75lt etrn8pwmoazewnw9s rl5nah0h5 aftbye2zzn4e8ngs01jfj0mta 3r6iqs10m,fnay1mkr94suxlpiappend all commits to our current brknch.
