 The format of the `state` field is determined by `BsonPlugin`.
 The code for `BsonPlugin` will have the details, but some high-level points about the BSON format:
 
-- It does not match the JSON format generated by `bosk-gson`. The two are not mutually compatible. This is a deliberate decision based on differing requirements.

 - It strongly favours objects over arrays, because object members offer idempotency and (ironically) stronger ordering guarantees.

+To configure an `ObjectMapper` that is compatible with a particular `Bosk` object, use the `JacksonPlugin.moduleFor` method.
+Here is an example:

+``` java
+JacksonPlugin jacksonPlugin = new JacksonPlugin();
+boskMapper = new ObjectMapper()
