+`seqspec` is a file format and tool that describe data generated from genomics experiments. Both the file format and tool [enable uniform processing](./docs/UNIFORM.md) of genomics data.
 
 A `seqspec` file contains
 
 1. Assay-level metadata such as library kit and sequencing machine,
 2. The 5'->3' annotation and position of the elements in a library molecule (e.g. barcodes, UMIs),
 3. A list of the reads generated from sequencing the library molecule.
 
-More specifically, `seqspec` is a machine-readable YAML file to describe the content of molecules in genomic libraries, the structure of reads generated from them, and how those are stored in files.
