I am new to Go and I am trying to setup a simple graph database using Cayley with BoltDB as the backend datastore. Right now I am trying to run cayley from the command line. Running this command:
cayley http --db="bolt"
Generates this error:

I feel like I am missing a step somewhere but I can't find any good documentation on using Cayley with Bolt. Any suggestions?
