+Jace.NET can be used in a couple of ways:
+
+To directly execute a given mathematical function using the provided variables:
+```csharp
+Dictionary<string, double> variables = new Dictionary<string, double>();
+variables.Add("var1", 2.5);
+variables.Add("var2", 3.4);
+
+CalculationEngine engine = new CalculationEngine();
+double result = engine.Calculate("var1*var2", variables);
+```
+
+To build a .NET Func accepting a dictionary as input containing the values for each variable:
+```csharp
+CalculationEngine engine = new CalculationEngine();
+Func<Dictionary<string, double>, double> function = engine.Build("var1+2/(3*otherVariable)");
+
+Dictionary<string, double> variables = new Dictionary<string, double>();
+variables.Add("var1", 2);
+variables.Add("otherVariable", 4.2);
+
+double result = function(2, 4.2);
+```
+
+To build a typed .NET Func:
+```csharp
+CalculationEngine engine = new CalculationEngine();
+Func<int, double, double> function = (Func<int, double, double>)engine.Function("var1+2/(3*otherVariable)")
+	.Parameter("var1", DataType.Integer)
+    .Parameter("otherVariable", DataType.FloatingPoint)
+    .Result(DataType.FloatingPoint)
+    .Build();
+
+double result = function(2, 4.2);
+```
