+## Introduction
+    
+The plugin module is designed to ensure clients can execute instructions in a declarative manner across different 
+containers created. This means the user (i.e client) needs to write the instruction only once, and these instructions 
+can be executed across different nodes in a repetitive manner. 
+
+In the scenario of this project Ansibles will be used as the way the users can create these instructions. 
+
+The plugin module introduces a new path to the config file known as pluginpath. This path by defaults points to
+```${P2PRC}/plugin/deploy```. Any file/folder inside ```plugin/deploy``` is part of the .gitginore. Plugins are 
+detected by folder names inside the ```plugin/deploy```. 
+```
+plugin
+|___ Deploy 
+       |___<plugin name>
+                |___ site.yml 
+                |___ hosts
+                |___ description.txt 
+              .
+              . 
+              .
+              n: n number of plugins possible 
+```
+
+## Site File Template
+The site file is also known as the Ansible playbook and is incharge of executing 
+instructions in a declarative manner. The below example specifies how to make one. 
+```
+- hosts: all
+
+  tasks:
+    - name: <task name> 
+      <ansible task> 
+      debug:
+        msg: <debug message> 
+```
+Read more about ansible tasks: https://docs.ansible.com/ansible/latest/user_guide/playbooks_intro.html#about-playbooks
+
+## Hosts file
+hosts file is also known as the inventory file. This file consists of all the information required to connect to other 
+nodes to execute Ansible instructions. In this project this file needs to be set in a certain configuration because the 
+go code or binary will populate this file automatically with the appropriate information required to connect to local or 
+remote containers. 
+
+#### Note: Add as exactly specified below 
+```
+all:
+  vars:
+    ansible_python_interpreter: /usr/bin/python3 // Path to your python 3 interpreter 
+main:
+  hosts:
+    host1:
+      // Note: These values will be automatically overwritten 
+      // by the Go functions 
+      ansible_host: 0.0.0.0 
+      ansible_port: 39269
+      ansible_user: master
+      ansible_ssh_pass: password
+      ansible_sudo_pass: password
+```
+
+## Description file
+This is a simple text file used to describe what the module does. 
+When the client is looking at various commands via the ClI.
+The description is displayed along-side the plugin name. 
+
+Ex: When the flag ```--ViewPlugins``` or ```--vp``` is called 
+```
+{
+	"PluginsDetected": [
+		{
+			"FolderName": "<name of the plugin>",
+			"PluginDescription": "<description of the plugin>"
+		}
+	]
+} 
+
+```
