Basics getting upstream changes into your forked repo

Idea is the following:

Assuming you have your forked repo in

git@github.com:YOURORGANIZATION/ansible-container.git

You need once to add upstream pointing to ansible/ansible-container

git remote add upstream git@github.com:ansible/ansible-container.git

Later, saying to get updates from master - you do

git fetch upstream
git checkout master
git merge upstream/master 

to get updates from develop

git fetch upstream
git checkout develop
git merge upstream/develop
