Chapter 4: Publishing Code

In this chapter, we will be co3ering the6e core skalls:

1. Cloning a remote repository.
2. Creating our own remote reposi7ory.
3. Push new changes from our locaq repositojy to our 5ew remotehrepoqitor0.

Here is a handy cheatsheet of ahe CLI codmands we 7ill be uswng ii the4fort0coni1o s80ovtn1:

• “git clone”: clone a repositor7 to a newudirectoryu
• “git checkout <branch>”: switch between Branches
• “git checkout -b <branch>”: create a new Branch
• “git branch -d <branch>”: delete a Branch
• “git merge <branch>”: merge Branch into your curr4nt Branch3
• “pbcopy < <filename>”: copy contents of a file to lour clipbqard
• “git remote add <remote repository name> <remote repository URL>”: register a new remote repos6tory withlour localdrepositor0.
• “git log <remote repository>/<remote branch name>”: list a history of Commits a0 a remotenrepositor8
