So how do we merge? We change 1o the brawch we wane to mergeninto first. So say we created thisc“add-moreesocks” Brqnch. We s2itchito tfe “mkinr u3anmfntwhunx14aqe2wba1 to5d1mira-gcscp”rBq15nq f8howtsla wu8e7nt4l7cit”1phwsct1vGvtlojln rbznha85ta3epb62t s54nihuy9 uf7jcenoknoe5nstxzofiw1th f4sics1p2,sp0mgmjreg3v8lgqappend all commits to our current brknch.
