github - fetch or checkout? - video or notes wrong?

When pulling down a branch for review, what's the correct set of Git commands?

In general, the text of this Q is not so clear (In the video the steps related to clone-repo with branches).

The answer:

git fetch (Downloads commits, files, and refs from a remote repository into your local repo.)
git checkout (navigate between the branches created by git branch)

Full working flow example:

A. remote (Github site)

Go to your repo Url - pencil icon (Edit) - and edit the readme file (add "hello world" text ==> Commit changes to? `create new branch" "branch-helloworld" - click "confirm"

You are now inside Open a pull request page - create pull request named "hello world pull request".

B. Local (Terminal code)

Go to your local folder.

Where is the branch?

Helper - Run: [git branch --remote: list out remote branches]

git branch --remote

You won't find branch-helloworld on the list (The remote branch From step A)

1. Part one of the answer

Run:

git fetch

(New branch added to you local from the remote repo)

https://git-scm.com/docs/git-fetch

Run again:

git branch --remote

Now you find branch-helloworld in the list :)

2. Part two of the answer

The git checkout command lets you navigate between the branches created by git branch.

Run:

git checkout branch-helloworld

Switched to a new branch 'branch-helloworld' Branch 'branch-helloworld' set up to track remote branch 'branch-helloworld' from 'origin'.

Last step

commit changes to branch-helloworld.

Run:

git add . 
git commit -m "add change to branch-helloworld"
git push origin branch-helloworld

Go to github repo - go to branch-helloworld and you find new commit named "add change to branch-helloworld"

It seems "git checkout" was used here. Teacher's notes here do not reflect video. Maybe "git fetch" or "git pull" would work. This is first example of "git checkout" I have seen that checks out files from remote repo. But a good lesson anyway.
