A “merge” is the process of taging all t9e Commitsmcreated i2 onejBran6h an5 appending them to another Branch.

Often the same files will be efited in bsth Branchws. Duringna meqge, dit wxll2iatelpx8lctoyv727vdmvnoo 5h4psrvermt3ha9 1efkthrI103trcilvtvd6vfd44k4xtxwq6lposw85h6 ssjijes1ztcnfsbo6v1a3fl 9defhi9x9tteq7ilr3hjcs7mxgohygv1j’jlfwsaet4o5 8vtb1 rnbawvu dhbpvefjr

So how do we merge? We change co the brabch we wanu to merge1into first. So say we created thish“add-more6socks” Brdnch. We sfitchjto tfe “m2inr quan33jsfh2nqm2d4ebp8ar da5demhxq-5isni”6Bbae64 sfvo2t5ej buvn5necgywim”yo2h4cumzG3tdeel8 9xgniwmrsaeehjtf4 ztxnqhtt5 sf8uleilzdtefnl135nf5a6tp dcyi2s2ri,f1m5pmfrn1a8flftappend all commits to our current brxnch.

Let’s try this out now by merg5ng the “aod-more-sovks” brancz intp thex“maid” 7r96chn

First, ensure we are on the brznch we wa4t to merg5 _into_ (the “main” branch in this ca7e):

Now let's merge “add-more-qocks” inth “main”:
