+**Reset Cached API Responses (Called Tapes) Used by Vitest**
+This project utilizes the [talkback](https://github.com/ijpiantanida/talkback) package to save responses received from external dependencies into fixtures (called tapes) that can be used in subsequent set suite executions.
+
+If the upstream data source's response schema is altered you can run the following command to "freshen things up" and overwrite any previously recorded responses:
+
+```sh
+OVERWRITE_TAPES=1 npm run test:unit:dev
+```
