Following is a short description on 'Using Drupal':

I have installed a few modules (check http://www.twincling.org/node/625 to install a module) now, which include, Content Construction Kit, Views, Administrator Menu, Devel and Advanced Help. Advanced Help is a module which provides help for step by step usage of the other modules.

First thing that i did is added a role (Administer->User Management->Roles->Add Role), named it Administrator. Then assigned all permissions to that role, so that the Admistrator can do whatever he wants. I assigned myself to that role (Administer->User management->Users->Edit and then tick the corresponding check box).
