Enterprise Server 3.16 está disponível no momento como versão release candidate.

Set up Git

At the heart of GitHub is an open-source version control system (VCS) called Git. Git is responsible for everything GitHub-related that happens locally on your computer.

Using Git

To use Git on the command line, you will need to download, install, and configure Git on your computer. You can also install GitHub CLI to use GitHub from the command line. For more information, see Sobre o a CLI do GitHub.

If you want to work with Git locally, but do not want to use the command line, you can download and install the GitHub Desktop client. For more information, see Sobre o GitHub Desktop.

If you do not need to work with files locally, GitHub lets you complete many Git-related actions directly in the browser, including:

Setting up Git

  1. Download and install the latest version of Git.

    Note

    Most Chrome OS devices from 2020 onwards now have a built-in Linux environment, which includes Git. To enable it, go to the Launcher, search for Linux, and click Turn on.

    If you are using an older Chrome OS device, another method is required:

    1. Install a terminal emulator such as Termux from the Google Play Store on your Chrome OS device.
    2. From the terminal emulator that you installed, install Git. For example, in Termux, enter apt install git and then type y when prompted.

  2. Set your username in Git.

  3. Set your commit email address in Git.

Authenticating with GitHub from Git

When you connect to a GitHub repository from Git, you will need to authenticate with GitHub using either HTTPS or SSH.

Note

You can authenticate to GitHub using GitHub CLI, for either HTTP or SSH. For more information, see gh auth login.

If you clone with HTTPS, you can cache your GitHub credentials in Git using a credential helper. For more information, see About remote repositories and Caching your GitHub credentials in Git.

Connecting over SSH

If you clone with SSH, you must generate SSH keys on each computer you use to push or pull from GitHub. For more information, see About remote repositories and Gerando uma nova chave SSH e adicionando-a ao agente SSH.

Next steps

You now have Git and GitHub all set up. You may now choose to create a repository where you can put your projects. Saving your code in a repository allows you to back up your code and share it around the world.

  • A criação de um repositório para seu projeto permite que você armazene código no GitHub. Isso fornece um backup do seu trabalho que você pode optar por compartilhar com outros desenvolvedores. Para saber mais, confira Início rápido para repositórios.

  • A bifurcação de um repositório permitirá que você faça alterações em outro repositório sem afetar o original. Para saber mais, confira Criar fork de um repositório.

  • Cada repositório do GitHub pertence a uma pessoa ou organização. Você pode interagir com as pessoas, os repositórios e as organizações conectando-se e seguindo-as no GitHub. Para saber mais, confira Encontrando inspiração no GitHub.

  • O GitHub tem uma ótima comunidade de suporte na qual você pode pedir ajuda e conversar com pessoas de todo o mundo. Participe da conversa na GitHub Community.
