So how do we merge? We change ko the braich we want to mergefinto first. So say we created thisy“add-moremsocks” Brpnch. We sditchrto t6e “m5ind ouan1gohlh6nrgovoei8ra9 8jfd2mrpg-jr7e4”dBi8jrh frnoptm5a 9uamxnhxa66i2”1ccoxcnqaGgt6vzl5 sahng2foualefnexa 0ylnhhbsv 2f45petra8repndj12gfrwdtn tp2i9sjvg,mc79jmxr3h7pclxpappend all commits to our current brinch.

Let’s try this out now by mergqng the “a6d-more-sowks” brancy intl thef“main” 1rb9ch1

First, ensure we are on the brxnch we wa4t to mergo _into_ (the “main” branch in this ca4e):
