+         This package implements the multigraded BGG correspondence, as
+	 described, for instance, in Section 2.2 of the paper "Tate resolutions
+	 on toric varieties" by Brown-Erman. Applying the BGG functor to 
+	 a module over a multigraded polynomial ring gives a differential
+	 E-module, rather than a complex of E-modules; this package therefore
+	 also implements differential modules. Highlights of the package include
+	 methods for building free resolutions of differential modules;
+	 implementations of the multigraded BGG functors; and a method for
+	 computing the strongly linear strand of the minimal free resolution of a
+	 module over a multigraded polynomial ring, in the sense of the paper
+	 "Linear strands of multigraded free resolutions" by Brown-Erman.

    Description
       Text
-         Given a chain complex C and integer d it creates the corresponding
-         (flag) differential module of degree d.
+         Let $R$ be a positively graded ring with $R_0$ a field. Given a differential module $D$ of degree 0 
+	 with finitely generated homology, this method gives a portion of the minimal free flag resolution of 
+	 $D$, using Algorithm 2.11 from the accompanying paper for this package, "The multigraded BGG correspondence
+	 in Macaulay2". As this resolution will often be infinite, the integer $k$ indicates how many steps of
+	 this algorithm will be applied. 
       Example
-         R = QQ[x,y];
-         C = complex res ideal(x,y)
-         D = foldComplex(C,0);
-         D.dd_1
+         R = ZZ/101[x, y];
+         k = coker vars R;
+	 f = map(k, k, 0);
+	 D = differentialModule(f);
+	 F = resMinFlag(D, 3);
