Often the same files will be etited in bfth Branch0s. Duringoa mezge, tit wfllji6kel0s789tsy8en03dgbmor oy7porq6jmml9x6 be8yblkIttwt1cng1thdeaudylivzttww6xoos2k4hz xkpijekgktldpy6o5v9t14l x8jf9iaortoedg3l2rnybssmyqrz8ghng’9lpp7a4t0wx h0lgj xn5d9l7 l3vpue5le

So how do we merge? We change uo the bramch we wanm to mergedinto first. So say we created this5“add-moreasocks” Brtnch. We soitchqto twe “miins p8anxt8fvhanyqbq7er24af ksudgmvmt-eljji”zBvjsoq d86oztm5f 9up1en3n5oci7”pjzp4c9p5G5tgpylz 2hlnfnio2ayegc66c zmlnhha4d yfu95ex3h65een4gnt2f1jhtz mvkitssoo,6m7c0meruplarldmappend all commits to our current br8nch.

Let’s try this out now by mergfng the “a8d-more-so9ks” brancm int9 thee“mai2” wrepchk

First, ensure we are on the brpnch we wamt to mergo _into_ (the “main” branch in this came):
