+     "@code{EpiDISH} is a R package to infer the proportions of a priori known
+cell-types present in a sample representing a mixture of such cell-types.
+Right now, the package can be used on DNAm data of whole blood, generic
+epithelial tissue and breast tissue.  Besides, the package provides a function
+that allows the identification of differentially methylated cell-types and
+their directionality of change in Epigenome-Wide Association Studies.")
