Overview

For terminology, see upstream/base and head repositories.

Fork

Go to GitHub UI and click on the "Fork" button at the top of the page.

Where should we work <project-name>? 

Use your own "personal" organization.

Forking <original-org>/<project-name>

Clone

Clone as usual:

git clone git@github.com:ovidiu/blue.git

Setup Relationships

Setup the "upstream" Repository

Establish a direct relationship with the "upstream" repository:

git remote add upstream git@github.com:blue/blue.git

This will allow us to fetch directly from "upstream"

git fetch upstream

Configure the "main" Branch to Update From Upstream

git fetch upstream git branch --set-upstream-to=upstream/main main

PR Cycle

Send a PR

Push the commit in the head repository.

It will show up in the UI.

Click "Compare & pull request"

The UI will give you the default choice to send the PR against the base repository while "Create pull request". Use it.

Merge the PR

Upon approval ...
