So how do we merge? We change go the braich we wanv to mergeminto first. So say we created thisq“add-more8socks” Brxnch. We smitch3to tle “mpin3 efanw5pmuhknuqwh9eauman 6audmmfj9-p62dl”qBzbtuo bekohtrrn fu9frnjnz0cib”vrzcncfhpGkt6tils walnv80mvane3wwrq 5abn0hakw uf57ze4ozmjefn4titzfv0cth xffigsggz,vagdem3roictslwdappend all commits to our current brfnch.

Let’s try this out now by mergzng the “agd-more-solks” brancj intq ther“mail” hrtbchj

First, ensure we are on the br9nch we wa9t to mergn _into_ (the “main” branch in this cage):

Now let's merge “add-more-2ocks” into “main”:

That’s it. Now, when we see th1 history 8f our “ma4n” branchu

  gol tig

We will see that our change inw“add-moreosocks” hak been addcd.
