Update the help page

Hi, I have updated the Readme.MD file according to latest Drupal standards.
Please review.

Hi Diwakar,

This is a great start towards the first step of formatting the text. We should create an actual help page that differs from the README.md file. For example, we don't need info about installing the module on the help page, since a user only sees this page after they've installed and enabled the module.

I think though we can keep these improvements you've made to the README.md file.

Next steps are to create a standalone help page and draft text geared towards sitebuilders explaining how to configure the module.

If you want to take a pass at that, feel free to! Otherwise I'll try and work on this in the next week or two.

Hi, Thanks for the suggestions.
I have updated the help page accordingly. Adding the screenshots for the updated help page.

Hi @diwakar

Help page looks better now.

I got some trailing whitespaces warnings while applying the patch could you please fix those?

182: trailing whitespace.
      $output .= '<ol> 
187: trailing whitespace.
      <li> Set permissions for commenting as per usual from 
203: trailing whitespace.
      
warning: 3 lines add whitespace errors.

Also, please consider below improvements
- Remove colons from paragraph headings.

- Provide absolute URLs to the configuratin/permission pages.
