 When you are working on dex it's convenient to use the `--no-db` flag. This starts up dex in a mode which uses an in-memory datastore for persistence. It also does not rotate keys, so no overlord is required.
 
-In this mode you provide the binary with paths to files for connectors, users, and emailer. There are example files you can use inside of `static/fixtures` named *"connectors.json.sample"*, *"users.json.sample"*, and *"emailer.json.sample"*, respectively.

 You can rename these to the equivalent without the *".sample"* suffix since the defaults point to those locations:
