Improve the module's main page to be more descriptive, in particular for beginners

@kiamlaluno, Please find the below patch for the above mention changes. Hope this will helps you.

Thanks

Unfortunately, renaming a module is a really 'disturbing' change. There are many references in many places and everybody already knows it by its name. I think the matter you pointed out can be achieve by improving the module description.

Yes, writing better documentation would help more than changing the module name.

That is. Suggestions and contributions for the description review are welcome here.
