Git concepts: pushing

Pushing in Git refers to the process of uploading your local repository content, including commits, references to branches, or tags, into a remote repository. The 'git push' command is used to transfer the data from the local repository to the remote repository.

When you make a commit, that change is only in your local repository. To share your changes with others, you need to push these changes to the remote repository. Once the changes are pushed, all other users who have access to the remote repository can see and access your updates by pulling the changes into their own local repositories.

Here's the basic usage of 'git push':

You start by committing your changes locally using 'git commit'.

Then, to upload your changes to the remote repository, you use 'git push'.

If you're pushing to a branch that's been checked out by someone else, and they have made changes that you do not have, Git will not let you push. You'll first have to pull their changes with 'git pull'.

In summary, 'git push' is used to upload local repository content to a remote repository. It's a core functionality of version control, enabling collaboration and synchronization between different local repositories.
