In this chapter, we had an overview of open source software and how to work with open source projects. Some of the major benefits of contributing to open source, such as decreasing integration cost for your product, were highlighted. We also learned the basics of Git and some more advanced Git commands, which can be used in combination with the sendmail binary, in order to send patches to an open source community. Finally, we took a walkthrough of a real-world example, by learning how to integrate the custom tool con2fbmap into meta-raspberrypi and send it for review to the Yocto Project community.

In the next chapter, we will summarize all that we have learned through this book by creating a home automation project.
