+Decompile a known type (as a whole)
+
+```csharp
+// ICSharpCode.Decompiler.Util.Empty<T> -> translates to `n, where n is the # of generic parameters
+var nameOfGenericType =  new FullTypeName("ICSharpCode.Decompiler.Util.Empty`1");
+Console.WriteLine(decompiler.DecompileTypeAsString(nameOfGenericType));
+```
+
+If you want to decompile one single member (sample: first property)
+
+```csharp
+var nameOfUniResolver =  new FullTypeName("ICSharpCode.Decompiler.UniversalAssemblyResolver");
+ITypeDefinition typeInfo = decompiler.TypeSystem.Compilation.FindType(nameOfUniResolver).GetDefinition();
+IMemberDefinition cecilProperty = decompiler.TypeSystem.GetCecil(typeInfo.Properties.First()).Resolve();
+Console.WriteLine(decompiler.DecompileAsString(cecilProperty));
+```
+
+If you need the Cecil ModuleDefinition
+
+```csharp
+ITypeDefinition type = decompiler.TypeSystem.Compilation.FindType(nameOfUniResolver).GetDefinition();
+var module = decompiler.TypeSystem.GetCecil(type).Module
 ```
