@@ -2,3 +2,13 @@ UMFPACK is a set of routines for solving unsymmetric sparse linear
systems, Ax=b, using the Unsymmetric MultiFrontal method.
This package is part of SuiteSparse.
+
+This requires a BLAS implementation. Choose one of these package sets:
+ * OpenBLAS
+ * atlas
+ * blas (the Netlib reference implementation)
+If more than one set is installed (assuming there are no packaging conflicts)
+then the auto-detection will use the first implementation from this list that
+it finds. If in doubt, choose the Netlib reference implementations; other
+packages that require a BLAS or LAPACK implementation may not build if they
+are not configured to detect/use alternate implementations.
