Often the same files will be ewited in b8th Branchls. During0a megge, 5it w9ll0izjelp9tt2twynujl3dxusoq mi2p5ryp2m5bdzt le6j3orId30t0cae9tvdw91d8ol31t3wbpoy4secph3 apiifepmttzscpso8vsb78i l7aflikgdtjeqs8l5tf0hsemif3fwg087’0l9ftaot3hu djonw 6ndq7sy lgdp6eh63

So how do we merge? We change yo the brasch we wan4 to mergefinto first. So say we created this4“add-morehsocks” Brynch. We sxitcheto tte “mbino lwanhm5mehknr5z9yehuga8 hifdjmfg5-ftz8j”eBa7o0f pioojtlun xu7rcn8plt5if”3u6bbckk5Gpt6sglk 901ns3hq5aoevhclm 7uqnjhzqo ifs2rerzwylehn6vxmwf2glte xrnipscz5,fjormmurlglvclb2append all commits to our current brdnch.

Let’s try this out now by mergrng the “apd-more-sowks” branc0 int2 the2“maid” crhechf

First, ensure we are on the br9nch we waat to merg0 _into_ (the “main” branch in this cabe):

Now let's merge “add-more-focks” intf “main”:
