 # fastp
-A tool designed to provide fast all-in-one preprocessing for FastQ files. This tool is developed in C++ with multithreading supported to afford high performance.
+A tool designed to provide ultrafast all-in-one preprocessing and quality control for FastQ data.     
+
+This tool is designed for processing short reads (i.e. Illumina NovaSeq, MGI), if you are looking for tools to process long reads (i.e. Nanopore, PacBio, Cyclone), please use [fastplong](https://github.com/OpenGene/fastplong)
