+# M3p2 Plugin
+
+**This README.md file should be modified to describe the features, installation, configuration, and general usage of this plugin.**
+
+The **M3p2** Plugin is for [Grav CMS](http://github.com/getgrav/grav). Extra code for the M3P2 Courses
+
+## Installation
+
+Installing the M3p2 plugin can be done in one of two ways. The GPM (Grav Package Manager) installation method enables you to quickly and easily install the plugin with a simple terminal command, while the manual method enables you to do so via a zip file.
+
+### GPM Installation (Preferred)
+
+The simplest way to install this plugin is via the [Grav Package Manager (GPM)](http://learn.getgrav.org/advanced/grav-gpm) through your system's terminal (also called the command line).  From the root of your Grav install type:
+
+    bin/gpm install m3-p2
+
+This will install the M3p2 plugin into your `/user/plugins` directory within Grav. Its files can be found under `/your/site/grav/user/plugins/m3-p2`.
+
+### Manual Installation
+
+To install this plugin, just download the zip version of this repository and unzip it under `/your/site/grav/user/plugins`. Then, rename the folder to `m3-p2`. You can find these files on [GitHub](https://github.com/goutte/grav-plugin-m3-p2) or via [GetGrav.org](http://getgrav.org/downloads/plugins#extras).
+
+You should now have all the plugin files under
+
+    /your/site/grav/user/plugins/m3-p2
+	
+> NOTE: This plugin is a modular component for Grav which requires [Grav](http://github.com/getgrav/grav) and the [Error](https://github.com/getgrav/grav-plugin-error) and [Problems](https://github.com/getgrav/grav-plugin-problems) to operate.
+
+### Admin Plugin
+
+If you use the admin plugin, you can install directly through the admin plugin by browsing the `Plugins` tab and clicking on the `Add` button.
+
+## Configuration
+
+Before configuring this plugin, you should copy the `user/plugins/m3-p2/m3-p2.yaml` to `user/config/plugins/m3-p2.yaml` and only edit that copy.
+
+Here is the default configuration and an explanation of available options:
+
+```yaml
+enabled: true
+```
+
+Note that if you use the admin plugin, a file with your configuration, and named m3-p2.yaml will be saved in the `user/config/plugins/` folder once the configuration is saved in the admin.
