+## Configuration
+
+### Environment variables
+
+When you start the Confluent Schema Registry image, you can adjust the configuration of the instance by passing one or more environment variables either on the docker-compose file or on the `docker run` command line. Please note that some variables are only considered when the container is started for the first time. If you want to add a new environment variable:
+
+- For docker-compose add the variable name and value under the application section in the [`docker-compose.yml`](https://github.com/bitnami/containers/blob/main/bitnami/schema-registry/docker-compose.yml) file present in this repository:
+
+    ```yaml
+    schema-registry:
+      ...
+      environment:
+        - SCHEMA_REGISTRY_DEBUG=true
+      ...
+    ```
+
+- For manual execution add a `--env` option with each variable and value:
+
+    ```console
+    $ docker run -d --name schema-registry -p 8081:8081 \
+      --env SCHEMA_REGISTRY_DEBUG=true \
+      --network schema-registry-tier \
+      --volume /path/to/schema-registry-persistence:/bitnami \
+      bitnami/schema-registry:latest
+    ```
