The following snippet of code setups a basic version of the SDK. You should insert it directly before the closing <body> tag on each page you want to load it:

<script type="text/javascript">
function mcReady()
{
    MC.init({
        game_id '<your game id>'
    }, onReady);
}

function onReady(){
   console.log("== MC.init complete ==");
   console.log("version="+MC.version);
}

(function(d, s, id, modules){
     var js, fjs = d.getElementsByTagName(s)[0];
     if (d.getElementById(id)) {return;}
     js = d.createElement(s); js.id = id;
     if (modules) js.setAttribute('data-modules', modules.join(','));
     js.src = "//static.miniclipcdn.com/js/sdk/v2.0/miniclip.js";
     fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'miniclipsdk', ['ads', 'unity']));
</script>

This code will load and initialize the SDK and activate the advertising and the unity modules.
