One thing I’d add to the readme is an example of how you’d use the database in an example application. From the docs, it’s clear that this isn’t a sql database (yet?), so it would be good to have an example to see how to use the database.

It might also be nice to have a description of what happens when you insert or get a record, so others can learn from the code too. Or can you comment here about what your favorite part of the code is? What did you figure out that you didn’t know before? If you’re using the project to learn about databases, what have you learned so far?
