```
git push origin master
```
The `origin` parameter is the name of the remote repository, and `master` is the name of the branch that you want to push. If you're pushing to a different branch, you'll need to specify the branch name instead of `master`.
Once you've pushed your changes, they will be available to anyone who has access to the remote repository.
**Pulling Changes from GitHub**
If you want to get the latest changes from the remote repository, you can pull them down to your local repository. To do this, use the following command:
```
git pull origin master
```
This will fetch the latest changes from the remote repository and merge them into your local branch. If there are any conflicts, you'll need to resolve them before you can continue.
**Conclusion**
Pushing and pulling changes to GitHub are two essential tasks for working with Git. By understanding how to do these things, you'll be able to collaborate with others on projects and keep your code up-to-date.
Here are some additional tips for pushing and pulling changes to GitHub:
* Make sure you're pushing to the correct remote repository.
* Use descriptive commit messages so that others can easily understand what you've changed.
* Pull changes regularly so that you're always working with the latest code.
* Resolve conflicts as soon as possible so that you don't lose track of your changes.
By following these tips, you can make the most of Git and GitHub.
