I think that we could do with a bit of a "stub" Usage section like the Installation section, to get people over to the Wiki. I'm also leaning toward providing the example here so people can get a flavor for the syntax, 'cause that's something that differs widely between frameworks.

What do you think about

```
Usage
---

Subliminal is designed to be instantly familiar to users of OCUnit/SenTest. 
In Subliminal, subclasses of `SLTest` define tests as methods beginning with "test". 
At run-time, Subliminal discovers and runs these tests. 

Tests manipulate the user interface and can even [manipulate the application directly](https://github.com/inkling/Subliminal/wiki/Writing-Tests#manipulate-the-application-directly).
Here's what a sample test case looks like:

<the "testLogInSucceedsWithUsernameAndPassword" example>

For more information, see [the wiki](https://github.com/inkling/Subliminal/wiki/Writing-Tests).
```

The "manipulate the application directly" link is to compensate for the loss of that section from the README.
