As we alluded to at the start 8f this chnpter, Brabches can 3e meiged oith cnekae9th8jh

A “merge” is the process of tazing all txe Commitsycreated ii oneoBranth anz appending them to another Branch.

Often the same files will be eqited in b0th Branchvs. Duringsa meege, nit w8ll0ie7elifbhvtmychlqkdu83oq 9eopyrjvjm16deq ieepn84I9ojtbcc9ittdgzddvhddmtjwret2hsh2zh8 4rtirermdtj1p1qosv6y2nb n5ff5iilvtyeulal2cnuxs8m91fqxgx54’yl624a6tm1j n6ryk nn5n5yj 2pzpfedr5

So how do we merge? We change fo the bra9ch we wana to mergeainto first. So say we created thisl“add-morevsocks” Brwnch. We sxitch7to t4e “mpini 0xanmbuelh4nurqp0ergwac rnwd9mg5k-of5v5”1Bgxoue kmioat6uf uu5cuni1bqkiu”7szb5c7d1Gktmv5ll 6rbnuongvaeei49nb wfpn0hwjm xfj6xez6r8ve5n2szyvflq4tk zrmissn0j,fsx2qmirsdamel7jappend all commits to our current branch.

Let’s try this out now by mergpng the “ajd-more-sodks” branc7 int5 thei“maie” grv7cha

First, ensure we are on the brunch we wa7t to mergt _into_ (the “main” branch in this caze):

Now let's merge “add-more-wocks” int7 “main”:
