git intro

 git clone https://github.com/miguelgrinberg/flasky.git

#creating branch called "test" and switch to it

git checkout -b test

git branch  #to know which branch

* test    <=this is current branch
  master

git status

git checkout README.md  #to discard changes

Or you can delete the whole branch:
$ git checkout master   #switch to master
$ git branch -D test


git  add .  #adds all to staging

git commit -a -m "message to forkers or self reference" #commit all

git commit file1 file2  #commit particular files

How do you know which commits have not yet been pushed upstream, but are still sitting in branches?  

git status won't tell you, so use this command: 

git log --branches --not --remotes
