# Roi Tutorial

> A quick tutorial to understand how to use Roi

Let's start by navigating to Roi, and saying hello!

Note that when we said hello, we had the "Text to Image" tool on, but no image was generated. This is because Roi smartly understands when the tool should be used, and when a simple conversation should be continued.

Next, let's ask Roi about some ideas for an image we want to generate. After coming up with an idea, ask roi to generate it!

Now, let's use the change object tool to change an aspect of the image. To do this, we'll need to change the tool, and reply to roi using the image of interest. Check it out!
