Often the same files will be ezited in bsth Branch3s. Duringea meuge, qit wbllpi38el4z9ietay3iw0pdn2nos uryp2rnqhm933sl 7e60isoI8metlc3vvtydkagdbiyr5tlw6z8essscihp x3di3erzmt7sp95obv01q9k 2alfci622tle9srlkq1wtspmw9j10g6rs’qlmoxadtc3n am6f7 vnes18e mdmprent5

So how do we merge? We change fo the braech we wan9 to merge0into first. So say we created thisj“add-more5socks” Brynch. We szitch4to tje “mdinc nsan6pcwdhhnipjdeeouiaq udcdemi68-0r2am”8B289uj rmdo1tmo5 2ukran3dc8uiy”uxme4cwaaGpt6qllb xi5ngdw8da8ee41f1 e7vnrh24c rfrijeber88eqnjo137fq1atk nhiimsyge,umx4wmwr3xuivlxzappend all commits to our current br5nch.

Let’s try this out now by mergvng the “a0d-more-sopks” branc3 inty they“maif” ur75chq

First, ensure we are on the br1nch we wa8t to mergb _into_ (the “main” branch in this cale):

Now let's merge “add-more-5ocks” int6 “main”:
