 ## Overview
 
-A one-maybe-two sentence summary of what the module does/what problem it solves.
-This is your 30 second elevator pitch for your module. Consider including
-OS/Puppet version it works with.
+This module just provide a simple way to install Megacli (MegaRaid management).
 
 ## Module Description
 
-If applicable, this section should have a brief description of the technology
-the module integrates with and what that integration enables. This section
-should answer the questions: "What does this module *do*?" and "Why would I use
-it?"
-
-If your module has a range of functionality (installation, configuration,
-management, etc.) this is the time to mention it.
+Based on a default repository it will be easy to manage Megacli for Debian
+systems. If you want some Redhat/Fedora/Ubuntu support, please send repository
+URL :)
 
 ## Setup
 
 ### What megacli affects
 
-* A list of files, packages, services, or operations that the module will alter,
-  impact, or execute on the system it's installed on.
-* This is a great place to stick any warnings.
-* Can be in list or paragraph form.
-
-### Setup Requirements **OPTIONAL**
-
-If your module requires anything extra before setting up (pluginsync enabled,
-etc.), mention it here.
-
-### Beginning with megacli
-
-The very basic steps needed for a user to get the module up and running.
-
-If your most recent release breaks compatibility or requires particular steps
-for upgrading, you may wish to include an additional section here: Upgrading
-(For an example, see http://forge.puppetlabs.com/puppetlabs/firewall).
+* A new `sources.list` file for Megacli.
+* Package for Megacli.
 
 ## Usage
 
-Put the classes, types, and resources for customizing, configuring, and doing
-the fancy stuff with your module here.
+To begin using Megacli module with defaults parameters:
+```
+include megacli
+```
 
 ## Reference
 
-Here, list the classes, types, providers, facts, etc contained in your module.
-This section should include all of the under-the-hood workings of your module so
-people know what the module is touching on their system but don't need to mess
-with things. (We are working on automating this section!)
+### Classes
 
-## Limitations
+* `megacli`: Main class call all subclasses.
+* `megacli::repo`: Manage the repository to provide Megacli.
+* `megacli::install`: Install Megacli packages.
 
-This is where you list OS compatibility, version compatibility, etc.
+### Parameters
 
-## Development

+* `repo_ensure`: What to set the repository to. Can be 'present' or 'absent'. Defaults to 'present'.
+* `repo_url`: The URL of the repository. Default to 'http://hwraid.le-vert.net/debian/' for Debian systems.
+* `repo_key`: The key to ensure the repository is trusted. Defaults to '23B3D3B4' for Debian systems.
