 The rich text block is gonna give you an array of inlines that's gonna allow for inline text formatting that you can see here. You've also got a text run that's defining a single run of formatted text. Now the containers category contains elements that are used to group multiple elements together. And these include elements such as an action set that's gonna display a set of actions that you see here. These two buttons will be listed in an action set. A container, that's gonna allow you to group a bunch of different items together. So in this case here we have a container that's got a text block and an image. The column and column set are gonna be able to let you define a region into columns allowing elements to all sit side by side. So for example, that's gonna allow us to do things like create kind of like a table based layout that you see here.
