+### Guide
+
+1. Build the app-config perf tests package `rush build -t perf-app-configuration`.
+2. Copy the `sample.env` file and name it as `.env`.
+3. Create a App Configuration resource and populate the `.env` file with `APPCONFIG_CONNECTION_STRING` variable.
+4. Run the tests as follows
+
+   - list configuration settings
+     - `npm run perf-test:node -- ListSettingsTest --warmup 2 --duration 7 --iterations 2 --parallel 2`
