+<h2> Three Steps of HGM </h2>
+<ol>
+<li> Find a holonomic system satisfied by the normalizing constant.
+We may use computational or theoretical methods to find it.
+Groebner basis and related methods are used.
+<li> Find an initial value vector for the holonomic system.
+This is equivalent to evaluating the normalizing constant and its derivatives
+at a point.
+This step is usually performed by a series expansion.
+<li> Solve the holonomic system numerically. We use several methods
+in numerical analysis such as the Runge-Kutta method of solving
+ordinary differential equations and efficient solvers of systems of linear
+equations.
