 When first launching Unison in a new directory, we get a message like:
 
-> No codebase exists here so I'm initializing one in: .unison/v2
+> No codebase exists in </your/home/directory>.
+> Run `ucm init` to create one there, then try again; or `ucm -codebase <dir>` to load a codebase from someplace else!
 
 What's happening here? This is the Unison Codebase Manager starting up and initializing a fresh codebase. We're used to thinking about our codebase as a bag of text files that's mutated as we make changes to our code, but in Unison the codebase is represented as a collection of serialized syntax trees, identified by a hash of their content and stored in a collection of files inside of that `.unison/v2` directory.

 ### A property-based test
 
-Let's test this a bit more thoroughly. `square` should have the property that `square a * square b == square (a * b)` for all choices of `a` and `b`. The testing library supports writing property-based tests like this. There's some new syntax here, explained afterwards:
