Drupal: Readable path

This toturial will show you how to replace the default path of drupal by custom path.
Example:

www.mysite.com/?q=node/add/article => www.mysite.com/?q=create-article
www.mysite.com/?q=node/1 => www.mysite.com/?q=hello-world

Using Path module, you can:

• Set the path for individual node with the Path module (on the node/add or node edit form).
• Add a URL alias at 'Administer > Configuration > Search and metadata > URL aliases'  in Drupal 7, 'Administer > Site buiding > URL aliases' in Drupal 6.
