This tutorial guides on how to install a module in Drupal.
1) From Drupal'a admin login main menu: Home >> Administration.
Click on MODULES
2) click on INSTALL NEW MODULE
3) Go to Drupal.org and search for the module you want to install. For example, to install the Administration menu: click here: http://drupal.org/project/admin_menu
Scroll downthe page to the Recommended releases to find the download for your release. I prefer using the .zip.
Right click on the filename and "copy link location".
Back to drupal now.
Paste the copied link location into the Install from a URL input box and click the Install button.
4) If the installation was successful, you'll see a message like this:
Click on Enable Newly added Modules, scroll down to the newly created Administration modules section.
5) Enable the Administration menu by ticking the check-box. Click on Save Configuration.
A change in the administration menu is immediately noticed.
The above procedure is applicable to just about any Drupal module fit for installation.
Thats all folks!
Additional tasks for the administration menu:
Find the Overlay and Toolbar modules among the core, disable it.
