+## Configuration
+
 By default, the script runs every 5 minutes to write json file to the <outputdir> above. This can be modified by updating the following line in the Dockerfile:
 ```
 RUN echo ' */5 * * * * /usr/local/bin/python3 /usr/cta-archive/archive.py ' >> /usr/cta-archive/cronjob
 
 # Where 5 indicates every 5th minute. 
 ```
+
+## Notes
+
+This script runs as root within the container. It probably shouldn't.
