What is Git?

OpenCommit is a platform for hosting Git repositories. If you are new to development, here is the short version of what that means.

Git vs. OpenCommit#

It is important to understand the difference between the tool and the service:

Git is the software that runs on your computer. It tracks the history of your files, allows you to “undo” changes, and manage different versions of your work.
OpenCommit is the hosting service (the “Forge”). It provides a place to store your Git repositories online, collaborate with others via Pull Requests, track bugs via Issues, and automate tasks with Actions.

Analogy: Git is like your word processor; OpenCommit is like a collaborative cloud drive where you share your documents.

Step 1 – Install Git#

macOS

brew install git

Linux

# Debian / Ubuntu
sudo apt update && sudo apt install git

# Fedora / RHEL
sudo dnf install git

# Arch
sudo pacman -S git

Windows
Download the installer from git-scm.com. We recommend using Git Bash for all subsequent commands.

Step 2 – Configure Your Identity#

Git requires a name and email to attribute your work. Run these commands in your terminal:

Unlike the Getting Started guide, this page provides a deeper reference for using SSH with Git, including key management, configuration, commit signing, and security best practices.

SSH and Git#

SSH is used by Git for secure, passwordless authentication when interacting with remote repositories. Instead of passwords, SSH relies on asymmetric key pairs:

Private key — stored securely on your machine, never shared
Public key — added to your OpenCommit account

When you connect, your client proves possession of the private key without ever transmitting it. This is fundamentally more secure than password-based authentication.
