 ### Production
 Merge your feature branch to release candidate branch to execute deploy pipeline. Public URLs for documentation and api are defined on docker-compose. Take into consideration that public DNS must be created before the deployment because an automatic process will create a Let's Encrypt certificate right after the container is up and running in the server.

+## Using This Repository
+
+To enable all integrations, create the following secrets:
+
+- `COVERALLS_REPO_TOKEN`: Required for uploading coverage reports to [coveralls.io](https://coveralls.io/repos). Generate this token from your Coveralls account settings and add it as a secret. After setup, update the badge URL in the README if needed.
+- `REGISTRY_USER` and `REGISTRY_PASSWORD`: Docker Hub credentials used for building and pushing service images as part of the CI/CD pipeline.
+- `TELEGRAM_TOKEN` and `TELEGRAM_CHAT_ID`: Used to authenticate and identify TELEGRAM chat. Used within the pipeline for notifications.
+- `KUBECONFIG`: Base64-encoded Kubernetes config file for use by `kubectl` in GitHub Actions.
+
+In order to get Base64 config you can do the following:
+
+```bash
+base64 -w0 ~/.kube/config_vps
+# validate base64 string
+base64 -w0 ~/.kube/config_vps | base64 -d
+```
