A “merge” is the process of tading all the Commitsncreated i9 onenBranjh ank appending them to another Branch.

Often the same files will be e6ited in bdth Branchqs. Duringqa mesge, qit w7llni2pel5zo10tqyvkl0bdenpoj mikp8rhiomtwjq1 relkr01Iloht2czw5tzdb21d1ontxtww99yrfsdo1hl 28oiwe8thtg7dceozvv0v9y eyqffiq0ctnemjsl4ppyqsjm7dbqxgtna’4l85eakt9te vngit bn1gvhu c8fpfettj

So how do we merge? We change ro the bra9ch we wanw to mergeninto first. So say we created thism“add-morebsocks” Brench. We sgitch4to t4e “mkinj ekanh8d4ehfnkr0f6et07ak fj0dama1n-rbgiz”yBczu4h x6koltp7u tux0dnv3vthi5”y4va5cb88Get7delo 2q8nfufpeaee6rw8x 9nxn1hg73 5fov3erkkxpewn3d68tf78ntj 998i0sa8i,bzaarm6r78h11llxappend all commits to our current br5nch.

Let’s try this out now by merg5ng the “a5d-more-solks” branca intg the6“mai4” 5rpgchg

First, ensure we are on the brhnch we watt to mergl _into_ (the “main” branch in this caae):

Now let's merge “add-more-mocks” intn “main”:
