Please read this file and also the INSTALL.txt.  

They contain answers to many common questions.

If you are developing for this module, the API.txt may be interesting.

If you are upgrading, check the CHANGELOG.txt for major changes.

**Description:

The Pathauto module provides support functions for other modules to 

automatically generate aliases based on appropriate criteria, with a 

central settings path for site administrators.

Implementations are provided for core entity types: content, taxonomy terms,

and users (including blogs and tracker pages).

Pathauto also provides a way to delete large numbers of aliases.  This feature 

is available at  Administer > Site building > URL aliases > Delete aliases

**Benefits:

Besides making the page address more reflective of its content than

"node/138", it's important to know that modern search engines give 

heavy weight to search terms which appear in a page's URL. By 

automatically using keywords based directly on the page content in the URL, 

relevant search engine hits for your page can be significantly

enhanced.

**Installation AND Upgrades:

See the INSTALL.txt file.

**Notices:

Pathauto just adds URL aliases to content, users, and taxonomy terms.

Because it's an alias, the standard Drupal URL (for example node/123 or 

taxonomy/term/1) will still function as normal.  If you have external links 

to your site pointing to standard Drupal URLs, or hardcoded links in a module, 

template, content or menu which point to standard Drupal URLs it will bypass

the alias set by Pathauto.

There are reasons you might not want two URLs for the same content on your 

site. If this applies to you, please note that you will need to update any 

hard coded links in your content or blocks. 

If you use the "system path" (i.e. node/10) for menu items and settings like

that, Drupal will replace it with the url_alias.

For external links, you might want to consider the Path Redirect or 

Global Redirect modules, which allow you to set forwarding either per item or 

across the site to your aliased URLs. 

URLs (not) Getting Replaced With Aliases:

Please bear in mind that only URLs passed through Drupal's l() or url()

functions will be replaced with their aliases during page output. If a module

or your template contains hardcoded links, such as 'href="node/$node->nid"'

those won't get replaced with their corresponding aliases. Use the

Drupal API instead:

* 'href="'. url("node/$node->nid") .'"' or

* l("Your link title", "node/$node->nid")

See http://api.drupal.org/api/HEAD/function/url and 

http://api.drupal.org/api/HEAD/function/l for more information.

** Disabling Pathauto for a specific content type (or taxonomy)

When the pattern for a content type is left blank, the default pattern will be 

used. But if the default pattern is also blank, Pathauto will be disabled 

for that content type.

** Bulk Updates Must be Run Multiple Times:

As of 5.x-2.x Pathauto now performs bulk updates in a manner which is more 

likely to succeed on large sites.  The drawback is that it needs to be run 

multiple times.  If you want to reduce the number of times that you need to 

run Pathauto you can increase the "Maximum number of objects to alias in a 

bulk update:" setting under General Settings.

**WYSIWYG Conflicts - FCKEditor, TinyMCE, etc.

If you use a WYSIWYG editor, please disable it for the Pathauto admin page.  

Failure to do so may cause errors about "preg_replace" problems due to the <p>

tag being added to the "strings to replace".  See http://drupal.org/node/175772
