 It requires BLAS++ and Random123.
 Right now we list RandBLAS and Random123 as separate dependencies, but in time
 we'll hide the Random123 dependency entirely within RandBLAS.
+RandBLAS can be installed separately, if desired.
+In the context of RandLAPACK, RandBLAS is used as a submodule and should be

 We give recipes for installing BLAS++, LAPACK++, and Random123 below.
