The process to install Git and the Heroku CLI can be done entirely through the Terminal. From here, we can even deploy our app.

Let's started by initializing a repository. Type "git init" and hit [[Enter]]

Next, make sure you're tracking your app's code but adding all files and writing your first commit message. To do this type "git add ." and hit [[Enter]]

Next, create your first commit message by typing "git commit -m "commit message"" and hit [[Enter]]

Now we'll create a Heroku remote via the command line interface. To do this. Type the following and hit [[Enter]]:
heroku create -a example-app

You can confirm that the remote has been properly set for Heroku by running the following command "git remote -v" and hit [[Enter]]

Finally, we can deploy our code by pushing from your local branch to the Heroku remote. Do this by typing the following command:
"git push heroku main" and hit [[Enter]]

Deploying your projects to Heroku gives you a stage to show off your code to the world. The best thing is that it is surprisingly simple to do. To deploy your GitHub repo to Heroku, follow these steps.
