# Astro documentation

Astro is a small CLI written in Python that helps you create simple pipelines for processing CSV data into other formats (basically a really simple ETL).

> Astro is primarily generated via AI, so please do your own validation before using in production or critical contexts

You can use Astro to quickly take CSV files, filter and transfor them and create any output you want. Pipelines are defined as "steps" which are just pure Python!
