Working with the vi editor in a Galileo's shell can be very stressful if you are beginning with Linux development, and want to check how your sensors work.

In this chapter, we'll have a closer look at the Wyliodrin development tool and what it can offer us. It is an online editor that makes it possible to build our applications just by dragging, dropping, and attaching components, just like Legos. It can also be used just as a simple editor for Python or JavaScript code. All the code is developed using its website, and it will be pushed to Galileo when you want to run it. Another great feature is that it allows you to build customizable dashboards and charts fed by your own data signals. This development tool is not entirely free, but you can use most of its resources with a nonpaying account. It is a really nice tool to help you debug and understand how your sensors work.

Let's set up our image to allow Wyliodrin to connect to it:
