+### Notes
+#### Adding different load patterns
+In `loadtest/util/config.ts` define an entry in the enum, extend the function that converts strings into enum values and add your desired configs.
+
+```typescript
+export enum CONFIG {
+  YOURCONFIG = "yourconfig",
+  // ...
+}
+export function getConfig(): CONFIG {
+  const config = __ENV["CONFIG"];
+  if (config == CONFIG.YOURCONFIG.toString()) return CONFIG.YOURCONFIG;
+  // ...
+}
+
+export function getDefaultOptions() {
+  const config = getConfig();
+  const maxVUs = MAX_VUS ?? 10;
+  switch (config) {
+    case CONFIG.YOURCONFIG:
+      return {
+        stages: [
+          { duration: "30s", target: maxVUs }, // ramp up to maxVUs
+          { duration: "30s", target: maxVUs }, // hold
+          { duration: "10s", target: 0 }, // ramp down
+        ],
+        // OPTIONAL: conditions to stop the test early
+        thresholds: {
+          http_req_failed: [{ threshold: "rate<0.10", abortOnFail: true }],
+          http_req_duration: [{ threshold: "p(95)<5000", abortOnFail: true }],
+        },
+      };
+      // ...
+  }
+}
+```
+
+#### Running against different environments
+In `charts/schulportal-load-tests/values.yaml` define a scenario with your desired base-url.
