We've learned some great stuff in this tutorial on taking Gatsby to production.
First, we learned two new CLI commands: gatsby build and gatsby serve. Then, we fixed a few bugs that didn't appear in the development build. Then, we learned about React Helmet and how to add SEO metadata to our site. Finally, we deployed to two major providers: Netlify and ZEIT Now.sh.
You've now reached the end of both this tutorial and the entire Up and Running with Gatsby series. Congratulations! Let's look a couple of options for where to go next in the final video.
