+     "This package provides functions for cognitive diagnosis modeling and
+multidimensional item response modeling for dichotomous and polytomous item
+responses.  It enables the estimation of the DINA and DINO model, the multiple
+group (polytomous) GDINA model, the multiple choice DINA model, the general
+diagnostic model (GDM), the structured latent class model (SLCA), and
+regularized latent class analysis.  See George, Robitzsch, Kiefer, Gross, and
+Uenlue (2017) @url{doi:10.18637/jss.v074.i02} for further details on
+estimation and the package structure.  For tutorials on how to use the CDM
+package see George and Robitzsch (2015, @url{doi:10.20982/tqmp.11.3.p189}) as
