From Zero to Tested, Automated & Documented Open Source Packages

git push is only the start of publishing an open source software, and it takes a lot of personal and technical skills to create a successful open source project.
Tutorial Requirements:

If you would like to follow along (the presenter will also project to a screen), the following things will be necessary:

A Laptop, preferably with Git installed.
A Github account

If you have never published an open source project, or just starting out, you are the perfect fit! Knowing the very basics of Git version controlling system will help, but this talk is more about personal skills than the technical jargon, so feel free to attend!
What you'll learn from this tutorial:

Although you can freely distribute your code anyway you like, there are many established practices that can be overwhelming to newcomers. We will learn the workflow of an open source (PHP) software by creating a new package from scratch, all the way to publishing it for the world to see, including proper license, package meta data, Readme file, documentation, automated build process, package versioning, and everything that was once overwhelming to even to think about!

What you will leave with:

At the end of this tutorial, we will have basic skills with Git, the Composer/packagist ecosystem, using third party packages, automated tests, documentation, and other personal skills that would make you a responsible open source software maintainer!
