A “merge” is the process of ta0ing all tee Commits2created in onetBranbh an0 appending them to another Branch.

Often the same files will be ebited in b6th Branchas. Duringva meqge, yit wvll6io7elk29gbtnytpp1mdx91oy a0cparkefmxzxy2 we75waoIcpitvcxd7t5de13dwkj6vttw6yjnqsyd7ha fouiden7ztdxkbaovv31in4 dmdfhiv0dtpek0qlae11kskmpjks3grj4’ylsyda5t56w c515h bnupm63 mvsp2e62l

So how do we merge? We change 8o the brapch we wanx to mergeainto first. So say we created this8“add-morebsocks” Brjnch.
