Default config location incorrect

File: engine/reference/commandline/cli.md

I am wondering if the default docker location for the options are incorrect:

Options:
      --config string      Location of client config files (default "/root/.docker")
  -D, --debug              Enable debug mode
      --help               Print usage
  -H, --host value         Daemon socket(s) to connect to (default [])
  -l, --log-level string   Set the logging level ("debug"|"info"|"warn"|"error"|"fatal") (default "info")
      --tls                Use TLS; implied by --tlsverify
      --tlscacert string   Trust certs signed only by this CA (default "/root/.docker/ca.pem")
      --tlscert string     Path to TLS certificate file (default "/root/.docker/cert.pem")
      --tlskey string      Path to TLS key file (default "/root/.docker/key.pem")
      --tlsverify          Use TLS and verify the remote
  -v, --version            Print version information and quit

According to the rest of that pages guide for example the section https://docs.docker.com/engine/reference/commandline/cli/#configuration-files or other online resources, the config file is stored in $HOME/.docker/config.json

I assume the same is true for the tls file locations.
