## What it is
fastp is an ultra-fast all-in-one FASTQ preprocessing and quality control tool written in C++. It handles adapter trimming, quality filtering, read splitting/merging, UMI processing, and QC reporting for short-read sequencing data.

## Use cases
- trim adapters from Illumina FASTQ reads
- quality control and filtering of NGS sequencing data
- preprocess FASTQ files before alignment
- remove low-quality reads and polyG tails
- split and merge paired-end FASTQ files
- extract UMIs from sequencing reads
- generate QC reports for FASTQ data

## When to choose
- you need fast, single-tool FASTQ preprocessing for short reads
- you want combined trimming, filtering, and QC reporting in one step
- you work with Illumina or MGI sequencing data
- you need batch processing of many FASTQ files

## When to avoid
- you are processing long reads from Nanopore or PacBio (use fastplong instead)
- you need highly specialized trimming algorithms not covered by fastp
- you require a GUI-only workflow
