Now that Git is installed, and it knows who you are, you can start using Git.
Git New Files
A new file is a file that you have created or copied into your project folder, but haven't told Git to watch.

Git and Remote Platforms
13 of 13 topics publishedGitHub Get Started
Welcome! This page will guide you through the first steps of using GitHub for version control and collaboration.
Git What is SSH?
SSH (Secure Shell) is a way to connect securely to remote computers and services, like Git repositories.
GitHub Add SSH
Now that you have generated your SSH key, you need to add your public key to your GitHub account.
GitHub Set Remote
Now that your SSH key is added to GitHub, you can securely connect your local repository to GitHub using SSH.
GitHub Edit Code
GitHub lets you edit files directly in your browser.
Pull from GitHub
In the last chapters, we made an account on GitHub and set up SSH.
Push to GitHub
When we have made changes locally, we want to update our remote repository with the changes.
GitHub Branch
On GitHub, access your repository and click the "master" branch button.
Pull Branch from GitHub
Now continue working on our new branch in our local Git.
Push Branch to GitHub
This chapter explains how to push a branch from your local computer to GitHub.
GitHub Flow
The GitHub Flow is a simple, effective workflow for collaborating on code using Git and GitHub.
GitHub Pages
GitHub Pages lets you publish a website directly from your repository. To enable it:
Git GUI Clients
Git GUI clients let you use Git with buttons and menus instead of typing commands.
Git Contribute
3 of 3 topics publishedGitHub Fork
However, Git does not allow you to add code to someone else's repository without access rights.
Git Clone from GitHub
Now we have our own fork , but only on GitHub. We also want a clone on our local Git to keep working on it.
GitHub Send Pull Request
We have made a lot of changes to our local Git.
Git Undo
6 of 6 topics publishedGit Revert
The git revert command undoes a previous commit by creating a new commit that reverses the changes.
Git Reset
The git reset command moves your current branch (HEAD) to a different commit.
Git Amend
Git Amend is a command that allows you to modify the most recent commit.
Git Rebase
Rebasing moves or combines a sequence of commits to a new base commit.
Git Reflog
git reflog records updates to the tip of branches and HEAD.
Git Recovery
Git recovery means getting back lost commits, branches, or files.
Git Advanced
10 of 10 topics publishedGit .gitignore
The .gitignore file tells Git which files and folders to ignore (not track).
Git .gitattributes
The .gitattributes file is a special file that tells Git how to handle specific files in your repository.
Git Large File Storage (LFS)
Git LFS (Large File Storage) is an extension for Git that helps you manage large files (like videos, images, or datasets) efficiently.
Git Signing Commits/Tags
Signing a commit is like putting your personal signature on your work.
Git Cherrypick & Patch
Cherry-pick lets you copy a single commit from one branch to another. It's useful when you want just one (or a few) changes, not everything from another branch.
Git Merge Conflicts
A merge conflict happens when two branches change the same part of a file.
Git CI/CD
CI/CD stands for Continuous Integration and Continuous Deployment/Delivery.
Git Hooks
Git hooks are scripts that run automatically when certain Git events happen, like making a commit or pushing code.
Git Submodules
Git submodules let you include one Git repository inside another as a subdirectory.
Git Remote Advanced
Remotes are references to remote repositories.
