 ### Deploying with private git submodules
 
 Dokku uses git locally (i.e. not a docker image) to build its own copy of your app repo, including submodules. This is done as the `dokku` user. Therefore, in order to deploy private git submodules, you'll need to drop your deploy key in `/home/dokku/.ssh/` and potentially add github.com (or your VCS host key) into `/home/dokku/.ssh/known_hosts`. The following test should help confirm you've done it correctly.
