composer: i can't install my package to my project using composer.

My composer.json:

{
    "name": "coinremitphp/coin-remitter",
    "description": "coin remitter sdk for php",
    "type": "library",
    "keywords": ["coinremitter", "php", "cryptocurrency", "payment gateway", "api"],
    "homepage": "https://coinremitter.com/",
    "license": "MIT",
    
    "authors": [
        {
            "name": "name",
            "email": "your@name.com"
        }
    ],

   
    "require": {
        "php": ">=5.3.0"
    },
    "require-dev": {
        "php": ">=5.3.0"
    },
    "autoload": {
        "psr-0": {
            "CoinRemitter": "src/"
        }
    },
    "extra": {
        "branch-alias": {
            "dev-master": "0.1-dev"
        }
    }

}

When I run this command:

composer require coinremitphp/coin-remitter

I get the following output:

 [InvalidArgumentException]                                                                                                                                  
  Could not find package coinremitphp/coin-remitter at any version for your minimum-stability (stable). Check the package spelling or your minimum-stability  

And I expected this to happen:the package should be install in project.
