## I've messed up my docker setup. How do I start from scratch?
1. Delete *all* docker containers, including ones that are created outside of the quickstart guide.
```
docker rm -f $(docker ps -aq)
```
2. Clear persistent storage for DataHub containers, assuming you didn't set `DATA_STORAGE_FOLDER` environment variable.
```
rm -rf /tmp/datahub
```
