+### Logs
+
+#### Get container logs to console:
+
+```bash
+docker logs $(docker ps -a -q --filter "ancestor=deepf/js-docker-isolation-provider:main")
+```
+
+#### Get container logs to file:
+
+Sometimes console cannot output the full logs so it might be helpful to store the entire container's logs as file. It can be done like this:
+
+```bash
+docker logs $(docker ps -a -q --filter "ancestor=deepf/js-docker-isolation-provider:main") > log.txt
+```
