Welcome, Suzie is a starter kit for WordPress. It offers a better way to build scalable WordPress sites by making sure the Wordpress core, assets/media and configuration are not stored in your source control. This enables support for multiple server setups. On top of this you have the options of using Mailgun for emails and built-in Varnish Cache support.
Suzie requires Composer. Please make sure it's installed before continuing.
$ curl -sS https://getcomposer.org/installer | php
$ sudo mv composer.phar /usr/local/bin/composer
Download the installer from getcomposer.org/download, execute it and follow the instructions.
Download the latest version of the Suzie and extract its contents into a directory on your server. Next, in the root, run.
$ composer install
Please ensure your domain points to the public folder. Now lets move on to explaining Composer.
