I am new to version control and I am confused about when to use git clone versus git remote. If I want to start working on an existing project from GitHub, do I need to use both? Does git clone automatically set up a remote for me, or is git remote a separate step I need to perform to keep my local code synced with the main repository? I want to understand the underlying mechanics of how these commands interact with the repository's metadata.

The main difference is that git clone is used to create a brand-new local copy of a remote repository, while git remote is used to manage the pointers to those remote versions. When you run git clone <url>, Git performs several steps: it initializes a new directory, downloads all the data from the source, and automatically sets up a remote named "origin" pointing back to that URL. On the other hand, git remote add <name> <url> is used when you already have a local repository and you want to connect it to a new online source. Essentially, cloning is a one-time setup for a project, while remote commands are used throughout the project's life to manage multiple upstream connections.
Can you clarify if you are working with a fork of a repository, and have you considered how git remote allows you to track both the original 'upstream' source and your own personal 'origin' simultaneously? In many open-source workflows, you use git clone for your fork but then must manually use git remote add upstream to keep your local environment updated with the original project's changes.
Think of git clone as downloading a whole book, whereas git remote is just adding a bookmark that tells your computer where to find the online version of that book for updates.
I agree with Deborah, that's a perfect analogy! I also find that understanding the .git/config file helps; when you run those commands, you're really just updating that text file with the URLs of your remote servers.
Steven, that 'upstream' distinction is vital for anyone collaborating on large projects. If you only rely on the 'origin' created by the initial clone of your fork, you'll quickly fall out of sync with the main codebase. By adding a second remote, you can fetch the latest updates from the main repo and merge them into your local branch before pushing your own features back to your origin. It's the standard way to handle Pull Requests without running into massive merge conflicts later.
