Man page?

Is there a particular reason the dokku command doesn't have a man entry? I'd be glad to write one (although I don't have a ton of experience with makefiles) unless we're worried about polluting the environment or something. I think a man page would be really helpful. Here was my first experience with the dokku command:
```bash
$ man dokku
No manual entry for dokku
See 'man 7 undocumented' for help when manual pages are not available.
$ dokku --help
# (silent failure)
$ dokku
# (chirp chirp)
$ dokku help
    backup:export [file]                            Export dokku configuration files
    backup:import [file]                            Import dokku configuration files
    config <app>                                    display the config vars for an app
    config:get <app> KEY                            display a config value for an app
    config:set <app> KEY1=VALUE1 [KEY2=VALUE2 ...]  set one or more config vars
    config:unset <app> KEY1 [KEY2 ...]              unset one or more config vars
    delete <app>                                    Delete an application
    help            Print the list of commands
    logs <app> [-t]                                 Show the last logs for an application (-t follows)
    plugins-install Install active plugins
    plugins         Print active plugins
    run <app> <cmd>                                 Run a command in the environment of an application
    url <app>                                       Show the URL for an application
    version                                         Print dokku's version
```
I may be completely oblivious to some problem here, though. Thanks!
