-## Requirements
-Laddr is built on the Emergence PHP framework and deployement engine, and requires an Emergence server to host it.
-
-Emergence takes just a few minutes to setup on a Linux VM, and is designed to have a fresh system to itself. Once launched
-it will configure services on the machine as-needed to host an instance of the application along with any other
-sites, clones, or child sites. The guides for Ubuntu and Gentoo are most up-to-date: http://emr.ge/docs/setup
-
-## Installation via Emergence (linked child)
--  Create an emergence site that extends v2.laddr.us
-
-## Installation from Git
--  Create an emergence site that extends skeleton.emr.ge (access key: 8U6kydil36bl3vlJ)
--  Upload contents of git repository using WebDAV client (CyberDuck is the best open-source option)
