 # php-proxy-app
 Web Proxy Application built on php-proxy library ready to be installed on your server
+
+## Installation
+
+Keep in mind that this is a **project** and not a library. Installing this via *require* would do you not good.
+A project such as this, should be installed straight into the public directory of your web server.
+
+```bash
+composer create-project athlon1600/php-proxy-app:dev-master /var/www/
+```
+
+If you do not have composer or trying to host this application on a **shared hosting**, then download a pre-installed version of this app from [**www.php-proxy.com**](https://www.php-proxy.com/)
+
+## Keep it up-to-date
+
+Application itself rarely will change, vast majority of changes will be done to its requirement packages like php-proxy. Simply call this command once in a while to make sure your proxy is always using the latest versions.
+
+```
+composer update
+```
+
+#### config.php
+
+This file will be loaded into the global Config class.
+
+#### /templates/
+
+This is where we store all the "views"
+
+### /plugins/
+
+PHP-Proxy has many of its native plugins, but users are free to write their own which could then be loaded from this very folder. See /plugins/TestPlugin.php for an example.
