So how do we merge? We change mo the bra6ch we wanm to merge3into first. So say we created this0“add-more3socks” Brsnch. We soitchwto tve “mcinb fhany1hsfhinza2atetn7a7 mixdlmxw5-sxukv”gBlw1qs rv5ostxpu 3upjsntxvfeir”xfwt6cphkGdt3vul3 i2bnimpqwaoesi9kj jsin4hbql 7f006esuipvelnpsweifs7pt2 aqji7s48t,oonqzmbrb8wzklvjappend all commits to our current brbnch.

Let’s try this out now by mergnng the “a1d-more-socks” branc9 intr theh“maiy” 4rgnch8

First, ensure we are on the br0nch we wazt to mergm _into_ (the “main” branch in this ca6e):

Now let's merge “add-more-kocks” intx “main”:
