How to initialize a git repository and linked it to a remote repository provider

For example we've just created a new project and want to push it to a remote repository. Here's what we need to do.

1. Find out what is the repository url, you can see it at github. For example: https://github.com/czetsuya/JAX-RS-REST-Security.git
2. Open command prompt
3. Change directory to where your project is.
4. In the command promp execute:
1. >git init
2. >git add .
3. >git commit -m "Initial commit"
4. >git remote add origin https://github.com/czetsuya/JAX-RS-REST-Security.git
5. >git push -u origin master

What if we already initialized our repository? Then we can already skip steps 4.1-4.3 and just execute:

1. >git remote add origin https://github.com/czetsuya/JAX-RS-REST-Security.git
2. >git push -u origin master
