Creating a repository on GitHub
After you create your repository on GitHub, you can customize its settings and content.
A repository contains all of your project's files and each file's revision history. You can discuss and manage your project's work within the repository.
About repository visibility
You can restrict who has access to a repository by choosing a repository's visibility: public, internal, or private.
Creating a new repository
You can create a new repository on your personal account or any organization where you have sufficient permissions.
Creating a repository from a template
You can generate a new repository with the same directory structure and files as an existing repository.
You can add a README file to your repository to tell other people why your project is useful, what they can do with your project, and how they can use it.
About code owners
You can use a CODEOWNERS file to define individuals or teams that are responsible for code in a repository.
About repository languages
The files and directories within a repository determine the languages that make up the repository. You can view a repository's languages to get a quick overview of the repository.
Licensing a repository
Public repositories on GitHub are often used to share open source software. For your repository to truly be open source, you'll need to license it so that others are free to use, change, and distribute the software.
Creating a template repository
You can make an existing repository a template, so you and others can generate new repositories with the same directory structure, branches, and files.
Creating an issues-only repository
GitHub does not provide issues-only access permissions, but you can accomplish this using a second repository which contains only the issues.
Limits for viewing content and diffs in a repository
Certain types of resources can be quite large, requiring excessive processing on GitHub. Because of this, limits are set to ensure requests complete in a reasonable amount of time.
Duplicating a repository
To duplicate a repository without forking it, you can run a special clone command, then mirror-push to the new repository.
