As developers we use Open Source Software all the time. However, few developers realize how easy it can be to contribute, or how impactful it can be on your career.

Join Dan for a guided how-to on making open source contributions. We'll cover everything from: rarely talked about benefits, finding potential opportunities, discussing the workflow, and writing pull requests. By the end of the talk, you will have a list of actionable steps for contributing to the projects you use regularly.
