-Description: What the package does (one paragraph).
+Description: HybridExpress can be used to perform comparative transcriptomics
+    analysis of hybrids (or allopolyploids) relative to their
+    progenitor species. The package features functions to perform exploratory
+    analyses of sample grouping, identify differentially expressed genes
+    in hybrids relative to their progenitors, classify genes in expression
+    categories (N = 12) and classes (N = 5),
+    and perform functional analyses. We also provide users with graphical
+    functions for the seamless creation of publication-ready figures that are
+    commonly used in the literature.
