It's almost Hacktoberfest (and my birthday), which means it's time for an anniversary sale of my book How to Open Source!

You can get a $15 discount with code `jointheheist`. If you buy before Midnight on September 30, you'll get an invite to the How To Open Source Slack group where we're hacking on contributions over Hacktoberfest. 👇🏻👇🏻👇🏻
