+To generate a new Sonarqube API Key you can navigate to [https://your-sonar-url/account/security/](https://your-sonar-url/account/security/).

+### Using docker
+You can also use the docker image instead of running the binary manually:
+
+```yaml
+// docker-compose.yml
+version: "3"
+
+services:
+  webhook:
+    image: herlon214/sonarqube-pr-issues:v0.1.6 # Check the latest version
+    restart: always
+    environment:
+      SONAR_API_KEY: my-sonar-api-key
+      GH_TOKEN: my-github-token
+      SONAR_ROOT_URL: https://sonar-url-without-trailing-slash
+      WEBHOOK_SECRET: my-hook-secret
+    ports:
+      - 8080
+```
+
 ### CLI
 This option is mostly to test, ideally you should use the webhook.
