This command performs staging, the first part of that two-step process. Git tracks changes to a developer's codebase, but it's necessary to stage and take a snapshot of the changes to include them in the project's history. The clone includes all the project's files, history, and branches. Git clone creates a local copy of a project that already exists remotely. It adds a hidden subfolder within the existing directory that houses the internal data structure required for version control.

Git init initializes a brand new Git repository and begins tracking an existing directory. Here are some common commands for using Git: These commands can be executed directly from the command line or by using an application like GitHub Desktop. To use Git, developers use specific commands to copy, create, change, and combine code. For more information, see ' GitHub flow.' GitHub and the command line Basic Git commands Then, using the GitHub flow, developers simply create a branch to work on updates, commit changes to save them, open a pull request to propose and discuss changes, and merge pull requests once everyone is on the same page. Work is organized into repositories where developers can outline requirements or direction and set expectations for team members. GitHub builds collaboration directly into the development process.

With collaboration layers like the GitHub flow, a community of 15 million developers, and an ecosystem with hundreds of integrations, GitHub changes the way software is built.

GitHub hosts Git repositories and provides developers with tools to ship better code through command line features, issues (threaded discussions), pull requests, code review, or the use of a collection of free and for-purchase apps in the GitHub Marketplace. Public repositories help teams work together to build the best possible final product. Through platforms like GitHub, Git also provides more opportunities for project transparency and collaboration. Using the command line or other ease-of-use interfaces, a Git repository also allows for: interaction with the history, cloning the repository, creating branches, committing, merging, comparing changes across versions of code, and more. Because Git is a DVCS, repositories are self-contained units and anyone who has a copy of the repository can access the entire codebase and its history. The commits can be organized into multiple lines of development called branches. The file history appears as snapshots in time called commits. Plus, Git makes it possible to align experts across a business to collaborate on major projects.Ī repository, or Git project, encompasses the entire collection of files and folders associated with a project, along with each file's revision history. Using branches, developers can safely propose changes to production code.īusinesses using Git can break down communication barriers between teams and keep them focused on doing their best work. With a DVCS like Git, collaboration can happen any time while maintaining source code integrity. From the moment they access the history of a project, the developer has all the context they need to understand it and start contributing.ĭevelopers work in every time zone. Git lets developers see the entire timeline of their changes, decisions, and progression of any project in one place. Git is commonly used for both open source and commercial software development, with significant benefits for individuals, teams and businesses. Git is the most popular distributed version control system. Unlike once popular centralized version control systems, DVCSs don't need a constant connection to a central repository.

In a distributed version control system, every developer has a full copy of the project and project history. Seeing a transparent history of changes, who made them, and how they contribute to the development of a project helps team members stay aligned while working independently.

VCSs give each contributor a unified and consistent view of a project, surfacing work that's already in progress. As developers make changes to the project, any earlier version of the project can be recovered at any time.ĭevelopers can review project history to find out: A version control system, or VCS, tracks the history of changes as people and teams collaborate on projects together.
