 1. The suite, notably in its `refRemote.json` file in each draft, expects a number of remote references to be configured.
    These are JSON documents, identified by URI, which are used by the suite to test the behavior of the `$ref` keyword (and related keywords).
-   Depending on your implementation, you may configure how to "register" these either by retrieving them from the `remotes/` directory at the root of the repository, *or* you may execute `bin/jsonschema_suite remotes` using the executable in the `bin/` directory, which will output a JSON object containing all of the remotes combined.
+   Depending on your implementation, you may configure how to "register" these *either*:
+
+    * by directly retrieving them off the filesystem from the `remotes/` directory, in which case you should load each schema with a retrieval URI of `http://localhost:1234` followed by the relative path from the remotes directory -- e.g. a `$ref` to `http://localhost:1234/foo/bar/baz.json` is expected to resolve to the contents of the file at `remotes/foo/bar/baz.json`
+
+    * or alternatively, by executing `bin/jsonschema_suite remotes` using the executable in the `bin/` directory, which will output a JSON object containing all of the remotes combined, e.g.:
+
+    ```
+
+    $  bin/jsonschema_suite remotes

+    ```json

 2. Test cases found within [special subdirectories](#subdirectories-within-each-draft) may require additional configuration to run.
    In particular, tests within the `optional/format` subdirectory may require implementations to change the way they treat the `"format"`keyword (particularly on older drafts which did not have a notion of vocabularies).
