  +### Removing a crate from the website
  +
  +Sometimes it might be needed to remove all the content related to a crate from
  +docs.rs (for example after receiving a DMCA). To do that, log into the server
  +and run:
  +
  +```
  +cratesfyi database delete-crate CRATE_NAME
  +```
  +
  +The command will remove all the data from the database, and then remove the
  +files from S3.
