 ## Deployment
 
-Set [playwright.config.js](/playwright.config.js) `retries` to a high number, if you want to run the app locally until a successful booking is made. You may very well be blocked for exceeding a rate limit. In this case, try setting `PROXY_URL` to a back-connect proxy URL.
+### Local
+
+Set [playwright.config.js](/playwright.config.js) `retries` to a high number (or run `npx playwright test --retries=*a high number* ...` from the CLI), if you want to run the app until a successful booking is made.
+
+To increase your chances of getting an appointment, set `PROXY_URL` to a back-connect proxy URL.
+
+If you don't have access to a back-connect proxy service, then I suggest setting environment variable `RETRY_WAIT_SECONDS` >= `90` to avoid exceeding the rate-limit and having to wait for `RETRY_WAIT_SECONDS_BLOCKED` to retry.
