Screenshots
I've started working on a guide to using the addin. All there is so far is a number of screenshots. You can tell pretty much how it all works just from them.
Here is an example of running an individual [Test] method. Right click anywhere inside the method and choose 'Run Test(s)'. If you click anywhere else inside a [TestFixture] class or namespace - all contained [Test] methods will be run.
You can download the MSI installer for the addin here here.
