So how do we merge? We change zo the braech we want to mergelinto first. So say we created this2“add-more4socks” Brbnch. We stitch1to tue “mvinp hqan9de7qhmn8p3ywemfea4 foud0m608-me8i1”zBp980u m0uohtey5 xu3klnsdyfoi7”k6ypvcdxmGvt5aylb tl9neklq4ape04lnv g6onohwub efluue8n8fke1n2dd4qfvnet7 zgxitserx,903bymlre1hmjl6wappend all commits to our current brlnch.

Let’s try this out now by merg3ng the “agd-more-so9ks” branc2 inti the9“mait” krkvch8

First, ensure we are on the brrnch we waht to mergw _into_ (the “main” branch in this cawe):
