To fetch images specifically from your account, set the get and userId options:

<script type="text/javascript">
    var userFeed = new Instafeed({
        get: 'user',
        userId: 'YOUR_USER_ID',
        accessToken: 'YOUR_ACCESS_TOKEN'
    });
    userFeed.run();
</script>

The next step is to find the userID and TokenAccess. If you don't want to create an Instagram account and want to use the one I created beforehand, you can go straight to the section titled Displaying the feed.
