+# Debugging with logs
+
+By default, Dozzle does not output a lot of logs. However this can be changed with `--level` flag. The default value is `info` which only prints limited logs. You can use `debug` or `trace` which will show details about memory, configuration and other stats. `DOZZLE_LEVEL` can be used in compose configurations. Below is an example of using `docker-compose.yml` file to enable `debug` level.
+
+```yaml
+version: "3"
+services:
+  dozzle:
+    image: amir20/dozzle:latest
+    volumes:
+      - /var/run/docker.sock:/var/run/docker.sock
+    ports:
+      - 8080:8080
+    environment:
+      DOZZLE_LEVEL: debug
+```
