+[![Build Status](https://travis-ci.org/EasyEngine/easyengine.svg?branch=master%2Fv4)](https://travis-ci.org/EasyEngine/easyengine)
+
+## Requirements
+
+* Docker
+* Docker-Compose
+* PHP CLI
+* PHP Modules - `curl`, `sqlite3`, `pcntl`
+
+## Installing
+
+### Mac
+
+Once you have verified the requirements exist, download the `easyengine.phar` file using `wget` or `curl` and give it executable permissions:
+
+```bash
+wget -O /usr/local/bin/ee https://raw.githubusercontent.com/EasyEngine/easyengine-builds/master/phar/easyengine.phar
+chmod +x /usr/local/bin/ee
+```
+
+### Linux
+
+For Linux, we have created an installer script which will install all the dependencies for you. We have tested this on Ubuntu 14.04, 16.04, 18.04 and Debian 8.
+
+```bash
+wget -qO ee rt.cx/ee4beta && sudo bash ee
+```
+
+Even if the script doesn't work for your distribution, you can manually install the dependencies and then run the following commands to install EasyEngine
+
+```bash
+wget -O /usr/local/bin/ee https://raw.githubusercontent.com/EasyEngine/easyengine-builds/master/phar/easyengine.phar
+chmod +x /usr/local/bin/ee
+```
+
+## Usage
+
+EasyEngine will currently only run with root privileges. You can run `ee help` or `ee help site` to get all the details about the various commands and subcommands that you can run.
