Branches

• Branch is just a text reference to the commit
• The pointer (to a commit) for all branches are located in .git/refs/heads

Branch merging

• Merge a secondary branch (feature) into the primary branch or receiving branch (master)
• A Pull Request (PR) must be made to ask the owner to merge the dev branch into the master
• GitHub/Pull requests tab -> New pull request
• Base (master) <- compare (dev)
• After a PR is created, all the future commits to dev branch will appear in the PR until it's closed
• Close PR finishes the PR with no merge
• Merge PR finishes the PR with merge to the master branch (all commits from dev are copied into master)
• When checking out to/from different branches the modifications are carried (moved) together! Until a commit is performed
