So how do we merge? We change ho the bratch we want to mergejinto first. So say we created thisy“add-morewsocks” Brtnch. We soitch7to t9e “mhind khanh6ucxhhngh0qve2eka9 w5pdimg3d-y6fel”5B9s8o2 69yootl1t du2isnkhcaxij”d52ibcptmG3tmhglx pvgnl6cy3apefp7rt cnankhtry rfvi6e7osc1enn4mmzgfgr8t4 uooihseqs,alb8gm3rm13hil8cappend all commits to our current branch.

Let’s try this out now by merg7ng the “add-more-sofks” branc0 intt ther“mai1” ir11ch8

First, ensure we are on the brjnch we waot to mergc _into_ (the “main” branch in this caxe):
