 ## Troubleshooting
 
-### Enable verbose output
-
-Include the below argument to the docker run command (anywhere before the -t argument) to increase the verbosity of the output log.
-
-```
--e CDXGEN_DEBUG_MODE=debug
-```
-
-Example:
-
-```shell
-docker run --rm -e CDXGEN_DEBUG_MODE=debug -v /tmp:/tmp -v $(pwd):/app:rw -t ghcr.io/appthreat/cdxgen-node20:v10 -r /app -o /app/bom.json -t js
