+## Usage
 
-Deno by default sandboxes applications like a web browser. To validate datasets located on your local system, you need to use the --allow-read flag to read local files. --allow-env is also required to allow for detection of OS specific features. These flags are included in the script line of the `./bids-validator-deno` script.
+To use the latest validator hosted at https://deno.land/x/bids_validator, use the following command:
+
+```console
+$ deno run --allow-read --allow-env https://deno.land/x/bids_validator/bids-validator.ts path/to/dataset
