Getting started with your GitHub account

With a user account on GitHub, you can import or create repositories, collaborate with others, and connect with the GitHub community.

This guide will walk you through setting up your GitHub account and getting started with GitHub's features for collaboration and community.

Part 1: Configuring your GitHub account

The first steps in starting with GitHub are to create an account, choose a product that fits your needs best, verify your email, set up two-factor authentication, and view your profile.

There are several types of accounts on GitHub. Every person who uses GitHub has their own user account, which can be part of multiple organizations and teams. Your user account is your identity on GitHub and represents you as an individual.

1. アカウントを作成する

To sign up for a GitHub account, navigate to and follow the prompts.

To keep your GitHub account secure you should use a strong and unique password. 詳しい情報については、「強力なパスワードを作成する」を参照してください。

2. Choosing your GitHub product

You can choose GitHub Free or GitHub Pro to get access to different features for your personal account. You can upgrade at any time if you are unsure at first which product you want.

For more information on all of GitHub's plans, see "GitHub's products."

3. メールアドレスを検証する

To ensure you can use all the features in your GitHub plan, verify your email address after signing up for a new account. 詳細は「メールアドレスを検証する」を参照してください。

4. Configuring two-factor authentication

2 要素認証、あるいは 2FA は、Web サイトあるいはアプリケーションにログインする際に使われる追加のセキュリティレイヤーです。 We strongly urge you to configure 2FA for the safety of your account. 詳しい情報については「2 要素認証について」を参照してください。

5. Viewing your GitHub profile and contribution graph

Your GitHub profile tells people the story of your work through the repositories and gists you've pinned, the organization memberships you've chosen to publicize, the contributions you've made, and the projects you've created. For more information, see "About your profile" and "Viewing contributions on your profile."

Part 2: Using GitHub's tools and processes

To best use GitHub, you'll need to set up Git. Git は、GitHub に関連してローカルコンピュータで発生するすべての動作の根本を担っています。 To effectively collaborate on GitHub, you'll write in issues and pull requests using GitHub Flavored Markdown.

1. Learning Git

GitHub's collaborative approach to development depends on publishing commits from your local repository to GitHub for other people to view, fetch, and update using Git. For more information about Git, see the "Git Handbook" guide. For more information about how Git is used on GitHub, see "GitHub flow."

2. Git をセットアップする

If you plan to use Git locally on your computer, whether through the command line, an IDE or text editor, you will need to install and set up Git. 詳細は「Git のセットアップ」を参照してください。を参照してください。

If you prefer to use a visual interface, you can download and use GitHub Desktop. GitHub Desktop comes packaged with Git, so there is no need to install Git separately. 詳細は「GitHub Desktop を使ってみる」を参照してください。

Once you install Git, you can connect to GitHub repositories from your local computer, whether your own repository or another user's fork. Git から GitHub リポジトリに接続した場合、HTTPS または SSH を使って、GitHub で認証する必要があります。 For more information, see "About remote repositories."

3. Choosing how to interact with GitHub

Everyone has their own unique workflow for interacting with GitHub; the interfaces and methods you use depend on your preference and what works best for your needs.

For more information about how to authenticate to GitHub with each of these methods, see "About authentication to GitHub."

方法説明Use cases
Browse to GitHub.comIf you don't need to work with files locally, GitHub lets you complete most Git-related actions directly in the browser, from creating and forking repositories to editing files and opening pull requests.This method is useful if you want a visual interface and need to do quick, simple changes that don't require working locally.
GitHub DesktopGitHub Desktop は、コマンドライン上でテキストコマンドを使うのではなく、ビジュアルインターフェースを使って、あなたの ワークフローを拡張し簡略化します。 For more information on getting started with GitHub Desktop, see "Getting started with GitHub Desktop."This method is best if you need or want to work with files locally, but prefer using a visual interface to use Git and interact with GitHub.
IDE or text editorYou can set a default text editor, like Atom or Visual Studio Code to open and edit your files with Git, use extensions, and view the project structure. For more information, see "Associating text editors with Git."This is convenient if you are working with more complex files and projects and want everything in one place, since text editors or IDEs often allow you to directly access the command line in the editor.
Command line, with or without GitHub CLIFor the most granular control and customization of how you use Git and interact with GitHub, you can use the command line. For more information on using Git commands, see "Git cheatsheet."

GitHub CLI is a separate command-line tool you can install that brings pull requests, issues, GitHub Actions, and other GitHub features to your terminal, so you can do all your work in one place. For more information, see "GitHub CLI."
This is most convenient if you are already working from the command line, allowing you to avoid switching context, or if you are more comfortable using the command line.
GitHub APIGitHub has a REST API and GraphQL API that you can use to interact with GitHub. For more information, see "Getting started with the API."The GitHub API would be most helpful if you wanted to automate common tasks, back up your data, or create integrations that extend GitHub.

4. Writing on GitHub

To make your communication clear and organized in issues and pull requests, you can use GitHub Flavored Markdown for formatting, which combines an easy-to-read, easy-to-write syntax with some custom functionality. 詳しい情報については、「GitHubでの執筆とフォーマットについて」を参照してください。

You can learn GitHub Flavored Markdown with the "Communicating using Markdown" course on GitHub Learning Lab.

5. Searching on GitHub

Our integrated search allows you to find what you are looking for among the many repositories, users and lines of code on GitHub. You can search globally across all of GitHub or limit your search to a particular repository or organization. For more information about the types of searches you can do on GitHub, see "About searching on GitHub."

Our search syntax allows you to construct queries using qualifiers to specify what you want to search for. For more information on the search syntax to use in search, see "Searching on GitHub."

6. Managing files on GitHub

With GitHub, you can create, edit, move and delete files in your repository or any repository you have write access to. You can also track the history of changes in a file line by line. For more information, see "Managing files on GitHub."

Part 3: Collaborating on GitHub

Any number of people can work together in repositories across GitHub. You can configure settings, create project boards, and manage your notifications to encourage effective collaboration.

1. Working with repositories


リポジトリは、プロジェクトのフォルダーのようなものです。 You can have any number of public and private repositories in your user account. Repositories can contain folders and files, images, videos, spreadsheets, and data sets, as well as the revision history for all files in the repository. For more information, see "About repositories."

When you create a new repository, you should initialize the repository with a README file to let people know about your project. 詳しい情報については「新しいリポジトリの作成」を参照してください。


You can clone an existing repository from GitHub to your local computer, making it easier to add or remove files, fix merge conflicts, or make complex commits. リポジトリをクローンすると、その時点で GitHub にあるすべてのリポジトリデータの完全なコピーがプルダウンされます。これには、プロジェクトのすべてのファイルとフォルダのすべてのバージョンも含まれます。 詳しい情報についてはリポジトリのクローンを参照してください。


A fork is a copy of a repository that you manage, where any changes you make will not affect the original repository unless you submit a pull request to the project owner. 一般的にフォークは、他のユーザのプロジェクトへの変更を提案するため、あるいは他のユーザのプロジェクトを自分のアイディアの出発点として活用するために使用します。 For more information, see "Working with forks."

2. プロジェクトのインポート

If you have existing projects you'd like to move over to GitHub you can import projects using the GitHub Importer, the command line, or external migration tools. For more information, see "Importing source code to GitHub."

3. Managing collaborators and permissions

リポジトリの Issue、プルリクエスト、プロジェクトボードを使ってプロジェクトで他者とコラボレーションできます。 You can invite other people to your repository as collaborators from the Collaborators tab in the repository settings. 詳しい情報については、「コラボレータを個人リポジトリに招待する」を参照してください。

You are the owner of any repository you create in your user account and have full control of the repository. Collaborators have write access to your repository, limiting what they have permission to do. 詳しい情報についてはユーザアカウントのリポジトリ権限レベルを参照してください。

4. リポジトリ設定を管理する

As the owner of a repository you can configure several settings, including the repository's visibility, topics, and social media preview. 詳しい情報については、「リポジトリ設定を管理する」を参照してください。

5. 健全なコントリビューションを促すプロジェクトをセットアップする

To encourage collaborators in your repository, you need a community that encourages people to use, contribute to, and evangelize your project. For more information, see "Building Welcoming Communities" in the Open Source Guides.

By adding files like contributing guidelines, a code of conduct, and a license to your repository you can create an environment where it's easier for collaborators to make meaningful, useful contributions. 詳しい情報については、「健全なコントリビューションを促すプロジェクトをセットアップする」を参照してください。

6. Using GitHub Issues and project boards

You can use GitHub Issues to organize your work with issues and pull requests and manage your workflow with project boards. For more information, see "About issues" and "About project boards."

7. Managing notifications

Notifications provide updates about the activity on GitHub you've subscribed to or participated in. 会話に関心がなくなった場合は、今後受信する通知の種類を、サブスクライブ解除、Watch 解除、またはカスタマイズできます。 詳しい情報については、「通知について」を参照してください。

8. GitHub Pages の活用

You can use GitHub Pages to create and host a website directly from a GitHub repository. For more information, see "About GitHub Pages."

9. GitHub Discussionsを使用する

You can enable GitHub Discussions for your repository to help build a community around your project. Maintainers, contributors and visitors can use discussions to share announcements, ask and answer questions, and participate in conversations around goals. 詳しい情報については「ディスカッションについて」を参照してください。

Part 4: Customizing and automating your work on GitHub

You can use tools from the GitHub Marketplace, the GitHub API, and existing GitHub features to customize and automate your work.

1. GitHub Marketplaceを使用する

GitHub Marketplace contains integrations that add functionality and improve your workflow. GitHub Marketplace で、GitHub App、OAuth App、GitHub Actions などの無料および有料ツールを見つけて確認し、インストールできます。 詳しい情報については、「GitHub Marketplace について」を参照してください。

2. Using the GitHub API

There are two versions of the GitHub API: the REST API and the GraphQL API. You can use the GitHub APIs to automate common tasks, back up your data, or create integrations that extend GitHub. For more information, see "About GitHub's APIs."

3. Building GitHub Actions

With GitHub Actions, you can automate and customize GitHub's development workflow on GitHub. 独自のアクションを作成したり、GitHubコミュニティで共有されたアクションを利用したりカスタマイズしたりできます。 詳しい情報については、「GitHub Actions を学ぶ」を参照してください。

4. Publishing and managing GitHub Packages

GitHub Packagesはソフトウェアパッケージのホスティングサービスであり、ソフトウェアパッケージをプライベートもしくはパブリックでホストでき、パッケージをプロジェクト中で依存関係として使えるようになります。 For more information, see “Introduction to GitHub Packages."

Part 5: Building securely on GitHub

GitHub has a variety of security features that help keep code and secrets secure in repositories. Some features are available for all repositories, while others are only available for public repositories and repositories with a GitHub Advanced Security license. For an overview of GitHub security features, see "GitHub security features."

1. リポジトリを保護する

As a repository administrator, you can secure your repositories by configuring repository security settings. These include managing access to your repository, setting a security policy, and managing dependencies. For public repositories, and for private repositories owned by organizations where GitHub Advanced Security is enabled, you can also configure code and secret scanning to automatically identify vulnerabilities and ensure tokens and keys are not exposed.

For more information on steps you can take to secure your repositories, see "Securing your repository."

2. Managing your dependencies

A large part of building securely is maintaining your project's dependencies to ensure that all packages and applications you depend on are updated and secure. You can manage your repository's dependencies on GitHub by exploring the dependency graph for your repository, using Dependabot to automatically raise pull requests to keep your dependencies up-to-date, and receiving Dependabot alerts and security updates for vulnerable dependencies.

For more information, see "Securing your software supply chain."

Part 6: Participating in GitHub's community

There are many ways to participate in the GitHub community. You can contribute to open source projects, interact with people in the GitHub Community Support, or learn with GitHub Learning Lab.

1. Contributing to open source projects

Contributing to open source projects on GitHub can be a rewarding way to learn, teach, and build experience in just about any skill you can imagine. For more information, see “How to Contribute to Open Source" in the Open Source Guides.
