+     "This package implements methods for batch correction and integration of
+scRNA-seq datasets, based on the Seurat anchor-based integration framework.
+In particular, STACAS is optimized for the integration of heterogenous
+datasets with only limited overlap between cell sub-types (e.g. TIL sets of
+CD8 from tumor with CD8/CD4 T cells from lymphnode), for which the default
+Seurat alignment methods would tend to over-correct biological differences.
+The 2.0 version of the package allows the users to incorporate explicit
+information about cell-types in order to assist the integration process.")
