Learn how to initialize a repository, add collaborators, define project settings, and configure access permissions to kickstart your development journey on GitLab.

Git Basics

Cloning a Repository

Cloning a repository from Totally Science GitLab allows you to download a copy of the codebase to your local machine, enabling offline development and experimentation. Git provides a simple yet powerful command-line interface for cloning repositories, with options to specify branch, depth, and authentication credentials.


This section covers the commands and procedures for cloning repositories using Git, along with tips for efficient repository management.

Making Changes

Once you have the repository cloned, you can start making changes to the code. GitLab supports a variety of development workflows, including feature branching, bug fixing, and refactoring. Learn how to modify files, add new features, refactor existing code, and stage changes for commit using Git’s powerful version control capabilities.

Committing Changes

Committing changes is a fundamental aspect of the Git workflow. A commit represents a logical unit of change to the codebase, accompanied by a descriptive commit message that explains the purpose and context of the changes. Discover the significance of meaningful commit messages, best practices for structuring commits, and techniques for organizing and managing commit history within GitLab repositories.

Pushing Changes to GitLab

After committing your changes locally, it’s time to push them to the remote repository on GitLab. GitLab repositories serve as a centralized hub for collaboration, enabling team members to share code changes, review each other’s work, and synchronize their local branches with the main repository. This section explores the process of pushing changes to GitLab, resolving potential conflicts, and synchronizing your local branch with the remote repository to maintain code consistency and integrity.
