The Power of Source Control With Git

In my life as a cook, there were many moments where I wish I had a reset button. That’s why I love source control using Git and GitHub. In three simple steps, you can protect your project from mistakes while also opening the door for better collaboration.

The first and most important step is to create a repository. That's where GitHub comes in. GitHub is able to remotely host our repository to allow us to collaborate with others while maintain the protection of source control.

Are second step is to connect the online repository with a local repository. This way we can update changes on our local machines before uploading them to everyone online. We use the term “git clone” to create a cloned copy of the online repository on our local machine.

Now we are in! The next and final step is all about updating the repository. We are going to use the following key terms: pull, add, commit, and push. “Pull” allows you to pull any updates from your repository and merge them with your local repository. “Add” allows you to stage changes for you to make a part of your local repository. “Commit” allows you to update local changes to your local repository without uploading those changes to everyone online. “Push” allows you to upload your local changes to your remote repository.

To demonstrate this we are going to create a new text file in our local repository, commit the changes to the local repository and then push the committed changes to the online repository.

As you can see, the local repository is able to update changes without updating the online repository until you are ready and use the “git push” command.

To show an example of “git pull” I am going to change the online repository and then pull the changes down to my local repository.

Through these simple steps, safe source controlled collaboration can be achieved. Making the reset button a very real tool for any software developer or project.
