Introduction
GitHub is a web-based app that lets you host files in repositories, collaborate on work, and track changes to files over time. Version tracking on GitHub is powered by the open source software Git. Whenever you update a repository on GitHub, Git tracks the changes you make.
There are many ways to work with GitHub, and you can choose a method that suits your level of experience, personal preferences, and the repositories you work with. For example, you can choose whether you want to work in the browser or from your desktop, how you want to use Git, and what capabilities you need from your editor and other software. You may choose to work with different repositories in different ways.
If you're new to GitHub, a good way to start contributing is to make changes in the browser on your GitHub Enterprise Server instance. As you become more familiar with GitHub and start contributing larger changes, you may want to start working with other tools. This article explains how to progress through these stages and helps you choose the best tool for your requirements at each stage. To quickly compare all the tools available for working with GitHub, see Comparison of tools for connecting to GitHub.
Getting started
In the user interface on your GitHub Enterprise Server instance, you can perform the whole "GitHub flow" for contributing to a repository, including creating a branch or fork, editing and previewing files, committing your changes, and creating a pull request. You can also upload files from your computer or download them from the repository. For more information, see
