How to install MarkLogic PHP library with (or without) composer?

I'm trying to follow the instructions on the official github page: https://github.com/marklogic/mlphp

I have composer globally. So I created a composer.json

{
  "requires": {
    "MarkLogic\MLPHP" : "dev-master"
  }
}

But when I call composer install it says:

Loading composer repositories with package information
Installing dependencies (including require-dev)
Nothing to install or update
Generating autoload files

And I can see the vendor adds the autoloader, nothing else, no mlphp. I've tried it several other ways, looking at google for hours and nobody seem to have the problem. Did I miss something?

Thanks!

Solution

Ach, there are typos in the README. It should read

{
    "require": {
        "marklogic/mlphp": "dev-master"
    }
}
