 Description: 
-    A suite of methods for using gene sets to quantify and evaluate the 
-    extent to which a given gene signature marks a specific phenotype. The package implements various 
-    scoring, enrichment and classification approaches, along with tools to compute 
-    performance metrics and visualize results, making it a valuable resource for transcriptomics research (bulk RNA-seq).
+    markeR is an R package that provides a modular and extensible framework for 
+    the systematic evaluation of gene sets as phenotypic markers using transcriptomic 
+    data. The package is designed to support both quantitative analyses and visual 
+    exploration of gene set behaviour across experimental and clinical phenotypes.
