GitHub: cloning and syncing work

If a repository already exists on GitHub, the usual starting point is not git init. It is git clone.

git clone copies a remote repository locally

To create a local copy of an existing GitHub repository:

git clone https://github.com/OWNER/REPO.git

This gives you:

• a local working copy of the repository
• the Git history
• a configured remote named origin

Cloning with SSH

If you use SSH authentication, clone with the SSH URL:

git clone git@github.com:OWNER/REPO.git

This sets up the remote to use SSH for all future pushes and pulls, avoiding credential prompts.

git fetch downloads remote updates without changing your current branch

To bring down remote information without integrating it into your current work yet:

git fetch

This is useful when you want to inspect what changed before updating your current branch.

git pull fetches and then updates the current branch

To download remote changes and integrate them into the current branch:

git pull

This is often the quick everyday sync command, but it helps to understand what it combines.

In broad terms:

• git fetch gets the new remote information
• git pull fetches and then updates the current branch

git pull --rebase keeps history linear

By default, git pull merges remote changes, which can create extra merge commits. Using --rebase replays your local commits on top of the fetched changes instead:

git pull --rebase

This produces a cleaner, linear history. You can configure Git to use rebase by default for all pulls:

git config --global pull.rebase true

Rebasing during a pull is safe as long as your local commits have not been pushed yet.

When to use clone, fetch, and pull

Use:

• git clone when you are getting the repository for the first time
• git fetch when you want the latest remote information without immediately updating your branch
• git pull when you want to bring the current branch up to date

A practical default

For beginner workflows:

• clone the repository once
• pull before starting a new piece of work
• fetch when you want a more cautious view of remote changes first

That default is simple and safe enough for most day-to-day use.
