You can also share ownership of a repository with other people in an organization, and give organization members access permissions to collaborate on your repository.

Repositories can be public or private. Public repositories are visible to everyone. Only the owner and collaborators can view or contribute to a private repository.


Fork is a copy of a repository.Forking allows users to experiment the project or prototype without affecting the original project.


Issues are suggested improvements, tasks or questions related to the repository. Issues can be created by anyone (for public repositories), and are moderated by repository collaborators. Each issue contains its own discussion forum, can be labeled and assigned to a user.


Branches are used in a project to commit changes to master repository or to create new modules.Making changes in branch does not affect the main project or main branch(master).



Pull requests let you tell others about changes you’ve pushed to a Git-Hub repository. Once a pull request is sent, interested parties can review the set of changes, discuss potential modifications, and even push follow-up commits if necessary.


Merging is also called integration,a fundamental operation used to join a successful branches to the master repository.
