Initializing git repo and setting remote

I have been creating a lot of git repos recently. I am tired of looking up the same information again and again.

I have been creating a lot of Java projects as I experiment with Spring Boot. After creating a repo, I experiment with it a bit, then decide if I want to keep working in it.

The first step is to change to the project directory and and a .gitignore file. I have been using Java on a Mac and this is the file I use.

Execute git init in the project folder. This creates the .git folder that is the local repo.

I am using GitHub to store remote copies of the repo. Create a new, empty repo and issue the commands:

git commit -m "first commit"
git remote add origin https://git-username@github.com/git-username/git-repo.git
git push -u origin master

After these commands, I can use git push to commit changes.
