+    (description
+     "This package provides a method to purify a cell type or cell population of
+interest from heterogeneous datasets.  scGate package automatizes marker-based
+purification of specific cell populations, without requiring training data or
+reference gene expression profiles.  scGate takes as input a gene expression
+matrix stored in a Seurat object and a @acronym{GM, gating model}, consisting of
+a set of marker genes that define the cell population of interest.  It evaluates
+the strength of signature marker expression in each cell using the rank-based
+method UCell, and then performs @acronym{kNN, k-nearest neighbor} smoothing by
+calculating the mean UCell score across neighboring cells.  kNN-smoothing aims
+at compensating for the large degree of sparsity in scRNAseq data.  Finally, a
+universal threshold over kNN-smoothed signature scores is applied in binary
+decision trees generated from the user-provided gating model, to annotate cells
+as either “pure” or “impure”, with respect to the cell population of interest.")
