In this section of the course, we're going to get into ruby gems. Ruby gems are incredibly powerful and they allow you to take someone else's code and very easily implement it into your own application so you can extend it without having to write all of that code yourself. Popular ruby gems can be great tools because they've been built by a large number of open source developers and you can leverage all the work they did in your own application.

I want to also focus on the best practices associated with using gems such as

• how to know the right version numbers to use
• how to research gems
• how to create your very own Ruby gem

Let's get into the guides.
