Git project setup

In the context of a new Salesforce project setup in Visual Studio Code (or outside of VSCode with any other platform code folder structure) the steps to follow for getting your project into a local and remote repository is as follows
1. Initialize git repo

git init

2. Set your user name

git config user.name "your username"

3. Set your checkin email identifier

git config user.email "your email address on github/bitbucket"

4. Add this folder structure to local git repo

git add .

5. When you are ready to commit

git commit --message "Commit Message / Ticket Number"

6. Up until this point, everything is local. Now lets add cloud repository (http or https)

git remote add origin https://username:password@github.com/accountname/reponame.git/
OR
git remote add origin http://username@cloudrepoApp.com/accountname/reponame.git/ (for password prompt)

7. Push code up to cloud repo

git push -u origin master

At any point you have to change username or password you can use the following and next time when you push or pull, git will ask for new password.

On Windows 
git config --global credential.helper wincred
On Mac
git config --global credential.helper osxkeychain
OR
git config --global --unset user.password
