 ## decoupler
 
-[decoupler](https://github.com/scverse/decoupler) enables inference biological activity from omics data using prior knowledge resources.  
-Compatible with transcriptomics and proteomics, it links data to transcription factors, pathways, or kinases.  
-It includes multiple inference methods such as enrichment scoring and linear models.  
-Designed for both bulk and single-cell, decoupler works directly with our scverse core data structures.
