+     "This package is an implementation of a regularized regression prediction
+and empirical Bayes method to recover the true gene expression profile in noisy
+and sparse single-cell RNA-seq data.  In @dfn{single-cell RNA sequencing}
+(scRNA-seq) studies, only a small fraction of the transcripts present in each
+cell are sequenced.  This leads to unreliable quantification of genes with low
+or moderate expression, which hinders downstream analysis.  This package
+@dfn{single-cell analysis via expression recovery} (SAVER) implements an
+expression recovery method for unique molecule index (UMI)-based scRNA-seq data
+that borrows information across genes and cells to provide accurate expression
+estimates for all genes.")
