 Polyhedra Module
 ================
 
+Polyhedron class allows users to build and inspect polyherons.
+
 .. py:class:: Polyhedron
 
-Polyhedra Properties
---------------------
+    .. py:property:: equalities
+
+        Returns a list of the equalities in a polyhedron.
+
+    .. py:property:: inequalities
 
-    .. py:method:: equalities(self)
-    
-        Return a list of the equalities in a set.
-        
-    .. py:method:: inequalities(self)
-    
-        Return a list of the inequalities in a set.
+        Returns a list of the inequalities in a polyhedron.
 
-    .. py:method:: constraints(self)
-    
-        Return ta list of the constraints of a set.
+    .. py:property:: constraints
+
+        Returns a list of the constraints of a polyhedron.
 
-Unary Operations
-----------------
     .. py:method:: disjoint(self)
-    
-        Returns this set as a disjoint set.
-               
+
+        Returns a polyhedron as a disjoint.
+
     .. py:method:: isuniverse(self)
-    
-        Return true if this set is the Universe set.    
 
-    .. py:method:: aspolyhedron(self)
-    
-        Return polyhedral hull of this set.
+        Return ``True`` if a polyhedron is the Universe set.
 
     .. py:method:: subs(self, symbol, expression=None)
-    
-        Subsitute expression into given set and returns the result.      
-        
-    .. py:method:: Lt(left, right)
-    
-        Assert first set is less than the second set.     
-        
-    .. py:method:: Le(left, right)
-    
-        Assert first set is less than or equal to the second set.
-        
-    .. py:method:: Eq(left, right)
-    
-        Assert first set is equal to the second set.         
-        
-    .. py:method:: Ne(left, right)
-    
-        Assert first set is not equal to the second set.          
-        
-    .. py:method:: Gt(left, right)
-    
-        Assert first set is greater than the second set.        
-
-    .. py:method:: Ge(left, right)
-    
-        Assert first set is greater than or equal to the second set. 
+
+        Substitutes an expression into a polyhedron and returns the result.
+
+To create a polyhedron, the user can use the following functions to define  equalities and inequalities as the constraints.
+
+.. py:function:: Eq(left, right)
+
+   Returns a Polyhedron instance with a single constraint as *left* equal to *right*.
+
+.. py:function:: Ne(left, right)
+
+   Returns a Polyhedron instance with a single constraint as *left* not equal to *right*.
+
+.. py:function:: Lt(left, right)
+
+   Returns a Polyhedron instance with a single constraint as *left* less than *right*.
+
+.. py:function:: Le(left, right)
+
+   Returns a Polyhedron instance with a single constraint as *left* less than or equal to *right*.
+
+.. py:function:: Gt(left, right)
+
+   Returns a Polyhedron instance with a single constraint as *left* greater than *right*.
+
+.. py:function:: Ge(left, right)
+
+   Returns a Polyhedron instance with a single constraint as *left* greater than or equal to *right*.
