 ## API
 
-Diffract provides the following methods:
+Diffract lives in the namespace `DEdge.Diffract`. Its main API is the class `Differ`, which provides the following methods:
 
 ```csharp
-void Diffract.Assert<T>(T expected, T actual, IDiffer<T> differ = null, PrintParams param = null)
+void Assert<T>(T expected, T actual, IDiffer<T> differ = null, PrintParams param = null)
 ```
 
 Computes the diff between two objects and, if it is not empty, throws an `AssertionFailedException` with the diff as message.
 
 ```csharp
-string Diffract.ToString<T>(T expected, T actual, IDiffer<T> differ = null, PrintParams param = null)
+string ToString<T>(T expected, T actual, IDiffer<T> differ = null, PrintParams param = null)
 ```
 
 Prints the diff between two objects to a string.
 
 ```csharp
-void Diffract.Write<T>(T expected, T actual, TextWriter writer = null, IDiffer<T> differ = null, PrintParams param = null)
+void Write<T>(T expected, T actual, TextWriter writer = null, IDiffer<T> differ = null, PrintParams param = null)
 ```
 
 Prints the diff between two objects to the given TextWriter (or to standard output if not provided).
 
 ```csharp
-FSharpOption<Diff> Diffract.Diff<T>(T expected, T actual, IDiffer<T> differ = null)
+FSharpOption<Diff> Diff<T>(T expected, T actual, IDiffer<T> differ = null)
 ```
 
 Computes the diff between two objects. Returns `None` if the objects are found to be equal.
