Documentation problem

For a true beginner, the Try Pandera page is a little vague and confusing.

There are several examples mixed together (some to show errors and some to show correct behavior) and when I tried to recreate the examples locally, I ran into several errors because I was missing something or overriding something accidentally.

There were also many assumptions in the explanations for features or concepts that beginners may not be familiar with and are necessary to understanding the library's functionality.

Suggested fix for documentation

My suggestion is to edit the existing TryPandera page to be clearer in its instructions, include more detailed explanations and more links to other helpful documentation pages or external pages, and to organize the page better so that a beginner can follow the flow more easily from start to finish.

I would love to work on this and provide some improvements to this documentation.
