 Decoy works well with [pytest][], but if you use another testing library or framework, you can still use Decoy! You just need to do two things:
 
-1. Create a new instance of [`Decoy()`](https://mike.cousins.io/decoy/api/#decoy.Decoy) before each test
-2. Call [`decoy.reset()`](https://mike.cousins.io/decoy/api/#decoy.Decoy.reset) after each test
+1. Create a new instance of [`Decoy()`](https://michael.cousins.io/decoy/api/#decoy.Decoy) before each test
+2. Call [`decoy.reset()`](https://michael.cousins.io/decoy/api/#decoy.Decoy.reset) after each test
 
 For example, using the built-in [unittest][] framework, you would use the `setUp` fixture method to do `self.decoy = Decoy()` and the `tearDown` method to call `self.decoy.reset()`. For a working example, see [`tests/test_unittest.py`](https://github.com/mcous/decoy/blob/main/tests/test_unittest.py).
