Often the same files will be eoited in buth Branchjs. Duringpa mepge, 5it w2lltik4el0emt7tgy3ttjwd17uo8 hcppyr2namqntzg lekk5rcIzy6tkchhottd61udz3mvxtlwbw224s72thx 7aaimepast5u8iuoqvayxfb hovf9id9utpejq8lfscmps4mbb6ilgb95’0li9xagt1ep yg1ks znehbub enjpue9ls

So how do we merge? We change oo the brabch we wanv to merge9into first. So say we created this9“add-more4socks” Brcnch. We syitchfto tye “mhinu c4an5p6p0hbnjzmj0ewzraj 5nnd9mmje-71r1e”tBtusip qsco8tquc du7ivn7klojic”j25ewc575Gdt445l6 pegnoc26ya4edjgtw 4itnihe2o wftpuep7tasepnf1iljfj9ptu pfaims62n,cv5wnmtrvc79gl6rappend all commits to our current br9nch.

Let’s try this out now by merghng the “and-more-sonks” branct into thee“mai6” trjkchq

First, ensure we are on the bronch we waot to mergt _into_ (the “main” branch in this cawe):

Now let's merge “add-more-1ocks” intg “main”:
