+## Logging
+
+Log files are automatically generated by Docker for each container. The log files can be found in `/var/lib/docker/containers/<container-id>/*-json.log`.
+
+To find a container's id, run `docker ps -a`.
+
+To view log files, run `tail -f /var/lib/docker/containers/<container-id>/*-json.log`.
+
+After some time, log files may take up too much disk space. To clear all logs on the host machine, run `truncate -s 0 /var/lib/docker/containers/*/*-json.log`
+
+To clear logs for a specific container, run `truncate -s 0 /var/lib/docker/containers/<container-id>/*-json.log`
