+% \section{Introduction}
+%
+% The \texttt{vgrid} package overlays a grid intended to help the author
+% enforce vertical rhythm on each page.  The spacing of the grid is taken from
+% \verb|\baselineskip|, with the first line at the top of the text area.
+%
+% Note that \texttt{vgrid} itself does not change any spacing -- other packages
+% (or careful font settings) must be used to achieve vertical rhythm. This document, for example, can be clearly seen to not have vertical rhythm.
+%
+% \section{Usage}
+%
+% To add a grid to each page, just place \verb|\usepackage{vgrid}| in your
+% document's preamble. As of this version, there is no fine-grained control to
+% allow grids to be excluded from certain pages. The grid will use
+% \verb|\baselineskip| as the line height.
