# installation
    npm install

  optionally
    npm install hiredis

# run service
    PORT=1337 node .

# add uri
    curl -F uri=https://mywaytoolonguri http://localhost:1337

  this will give you a relative shortened uri.

# resolve uri

  if you have changed `redisPrefix`, then use that instead of `go:`.
