# Why to follow this tutorial?


## First - what do I get if I follow this?

You can very easily install CAT PowerShell module from the official Microsoft PowerShell gallery. In this tutorial, you'll learn how to install it and create a fully working project with a few sample tests on dummy CSV data:

*Results of tests in a provided sample project.*

You will be able to explore the sample tests and run them. **It will give you a rough idea what CAT can check for you on your real data.** (The sample project works with CSV files, but CAT supports [many providers](https://docs.justcat.it/reference/data-sources/providers/overview/ "Providers")).

> **😺:** If command-line is something you'd like to avoid, you might prefer the get-started guide for [CAT Studio](https://docs.justcat.it/get-started/cat-studio/what-is-cat-studio/ "Get started with CAT Studio") instead.




## What do I need to follow?

On the other hand - what do you not need?

* You do NOT need admin permissions
* You do NOT need to pay anything or enter a credit card - a free trial covers this whole tutorial
* You do NOT need to connect to your data (sample data is provided)
