Now that we’ve created the VUI for our BMI skill, we are ready to write the code in the back end that makes the skill actually do something interesting. In our case, this is calculating the BMI.

Then, in the next chapter, we’ll go through the process of getting our skill certified and published to the Alexa Skills Store.
Before we can write the code, though, we need to install the tools.
