 ### Examples
-**Use `gget ref` in combination with [kallisto | bustools](https://www.kallistobus.tools/kb_usage/kb_ref/) to build a reference index:**
-```bash
-kb ref -i INDEX -g T2G -f1 FASTA $(gget ref --ftp -w dna,gtf homo_sapiens)

-→ kb ref builds a reference index using the latest DNA and GTF files of species **Homo sapiens** passed to it by `gget ref`.
