GitHub Enterprise Server is a code hosting platform for version control and collaboration. It lets you and others work together on projects from anywhere.
This tutorial teaches you GitHub Enterprise Server essentials like repositories, branches, commits, and pull requests. You'll create your own Hello World repository and learn GitHub Enterprise Server's pull request workflow, a popular way to create and review code.
In this quickstart guide, you will:
- Create and use a repository
- Start and manage a new branch
- Make changes to a file and push them to GitHub Enterprise Server as commits
- Open and merge a pull request
To complete this tutorial, you need a GitHub Enterprise Server account and Internet access. You don't need to know how to code, use the command line, or install Git (the version control software that GitHub Enterprise Server is built on). If you have a question about any of the expressions used in this guide, head on over to the glossary to find out more about our terminology.
A repository is usually used to organize a single project. Repositories can contain folders and files, images, videos, spreadsheets, and data sets -- anything your project needs. Often, repositories include a README file, a file with information about your project. README files are written in the plain text Markdown language. You can use this cheat sheet to get started with Markdown syntax. GitHub Enterprise Server lets you add a README file at the same time you create your new repository. GitHub Enterprise Server also offers other common options such as a license file, but you do not have to select any of them now.
hello-world repository can be a place where you store ideas, resources, or even share and discuss things with others.
ページの右上角で ドロップダウンメニューを使い、New repository（新規リポジトリ）を選択してください。
In the Repository name box, enter
In the Description box, write a short description.
Select Add a README file.
Select whether your repository will be Public or Private.
[Create repository] をクリックします。
Branching lets you have different versions of a repository at one time.
By default, your repository has one branch named
main that is considered to be the definitive branch. You can create additional branches off of
main in your repository. You can use branches to have different versions of a project at one time. This is helpful when you want to add new features to a project without changing the main source of code. The work done on different branches will not show up on the main branch until you merge it, which we will cover later in this guide. You can use branches to experiment and make edits before committing them to
When you create a branch off the
main branch, you're making a copy, or snapshot, of
main as it was at that point in time. If someone else made changes to the
main branch while you were working on your branch, you could pull in those updates.

Have you ever saved different versions of a file? Something like:
Branches accomplish similar goals in GitHub Enterprise Server repositories.
Here at GitHub Enterprise Server, our developers, writers, and designers use branches for keeping bug fixes and feature work separate from our
main (production) branch. When a change is ready, they merge their branch into
- Click the Code tab of your
- Click the drop down at the top of the file list that says main.
- Type a branch name,
readme-edits, into the text box.
- Click Create branch: readme-edits from main.
Now you have two branches,
readme-edits. Right now, they look exactly the same. Next you'll add changes to the new branch.
When you created a new branch in the previous step, GitHub Enterprise Server brought you to the code page for your new
readme-edits branch, which is a copy of
You can make and save changes to the files in your repository. On GitHub Enterprise Server, saved changes are called commits. Each commit has an associated commit message, which is a description explaining why a particular change was made. Commit messages capture the history of your changes so that other contributors can understand what you’ve done and why.
readme-editsbranch you created, click the README.md file.
In the editor, write a bit about yourself. Try using different Markdown elements.
In the Commit changes box, write a commit message that describes your changes.
[Commit changes] をクリックしてください。
These changes will be made only to the README file on your
readme-edits branch, so now this branch contains content that's different from
Now that you have changes in a branch off of
main, you can open a pull request.
Pull requests are the heart of collaboration on GitHub Enterprise Server. When you open a pull request, you're proposing your changes and requesting that someone review and pull in your contribution and merge them into their branch. Pull requests show diffs, or differences, of the content from both branches. The changes, additions, and subtractions are shown in different colors.
As soon as you make a commit, you can open a pull request and start a discussion, even before the code is finished.
By using GitHub Enterprise Server's
@mention feature in your pull request message, you can ask for feedback from specific people or teams, whether they're down the hall or 10 time zones away.
You can even open pull requests in your own repository and merge them yourself. It's a great way to learn the GitHub Enterprise Server flow before working on larger projects.
Click the Pull requests tab of your
Click New pull request
In the Example Comparisons box, select the branch you made,
readme-edits, to compare with
Look over your changes in the diffs on the Compare page, make sure they're what you want to submit.
Create pull requestをクリックします。
Give your pull request a title and write a brief description of your changes. You can include emojis and drag and drop images and gifs.
Optionally, to the right of your title and description, click the next to Reviewers. Assignees, Labels, Projects, or Milestone to add any of these options to your pull request. You do not need to add any yet, but these options offer different ways to collaborate using pull requests. 詳しい情報についてはプルリクエストについてを参照してください。
Create pull requestをクリックします。
Your collaborators can now review your edits and make suggestions.
In this final step, you will merge your
readme-edits branch into the
main branch. After you merge your pull request, the changes on your
readme-edits branch will be incorporated into
Sometimes, a pull request may introduce changes to code that conflict with the existing code on
main. If there are any conflicts, GitHub Enterprise Server will alert you about the conflicting code and prevent merging until the conflicts are resolved. You can make a commit that resolves the conflicts or use comments in the pull request to discuss the conflicts with your team members.
In this walk-through, you should not have any conflicts, so you are ready to merge your branch into the main branch.
- Click Merge pull request to merge the changes into
- Confirm merge（マージを確認）をクリックしてください。 You will receive a message that the request was successfully merged and the request was closed.
- Click Delete branch. Now that your pull request is merged and your changes are on
main, you can safely delete the
readme-editsbranch. If you want to make more changes to your project, you can always create a new branch and repeat this process.
By completing this tutorial, you've learned to create a project and make a pull request on GitHub Enterprise Server.
Here's what you accomplished in this tutorial:
- Created an open source repository
- Started and managed a new branch
- Changed a file and committed those changes to GitHub Enterprise Server
- Opened and merged a pull request
Take a look at your GitHub Enterprise Server profile and you'll see your work reflected on your contribution graph.
