 ## The Simplest Thing That Works
 
 The place to start is with a very simple service: a key-value store.
-You can set values, you can get values, and that's about it.
+You can set values, you can fetch values, and that's about it.
 We'll use it something like this:
 
 ```erlang
 S = kvstore:start().
 kvstore:set(name, "Colin", S).
-V = kvstore:get(name, S).
+V = kvstore:fetch(name, S).
 ```
 
 Behind the scenes, we're spinning off an Erlang process and sending messages to it.

 That's it for a basic, functioning service. Now let's mess with it a bit.
-If we look at the message passing, we see that `set` is a one-way request, and `get` is a two-way request.
