# Step-by-Step Tutorials

These tutorials walk you through a simple use case for NVIDIA Parabricks, giving a brief introduction to
how it works. We'll start by downloading some sample data:

* A reference file (`Homo_sapiens_assembly38.fasta`) and its index
* A 'known indels' file and its index
* Two FASTQ files
* Associated index files
* One BAM file for markdup
* One single-ended BAM file

The tutorials then walk through the following steps:

* Alignment (FASTA + FASTQ ==> BAM)
* Variant calling (FASTA + BAM ==> VCF)

These tutorials are meant to be simple and straightforward and to only cover a single, specific
use case. You should be able to copy and paste the commands into a terminal window and get
the same results as shown. The [Detailed Tutorials for Parabricks Pipelines](/tutorials/detailed-tutorials) cover more general problem solving using
Parabricks.
