# Behold! The Happy Path To Captivate Your Users With Stunning CLI Apps!

As developers, we often have to create command-line applications, which expose APIs, workflows or data processing functionality in a way that is accessible to scripts and non-developers. Although a simple command-line application can be created by only using `Array[String]`, such applications lack features that users take for granted, including:

* Flexible subcommands
    
* Options
    
* Arguments
    
* Validations
    
* Documentation pages
    

In this presentation at [Functional Scala 2022](https://www.functionalscala.com/), I've shown how to easily build beautiful command-line applications that your users will love. Using [ZIO CLI](https://github.com/zio/zio-cli), your command-line applications will support:

* All types of command-line parameters
    
* Perform both *Pure* and *Impure* validation
    
* Generate *beautiful* short and long documentation pages
    
* Support *auto-correction* plus *auto-completion*
    

Discover how you can have fun creating beautiful command-line apps that delight your users!
