Configuring/using Drupal Pathauto module I am new to Drupal. I just installed Drupal 8 and pathauto module.

Now I need to configure path patterns or whatever they are called.

On page https://www.drupal.org/documentation/modules/pathauto they give the path for configuring as: 

For 7.x, 8.x: Administer > Configuration > Search and Metadata > URL aliases, in the "Patterns" tab.

But can't see "Patterns" tab. When I click http://localhost/admin/config/search/path/add I get to a page with a form and 2 fields:
1. Existing system path
2. Path alias

I also tried http://localhost/admin/config/search/path/pathauto and http://localhost/admin/config/search/pathauto but they both give me 'Page not found'.

How do I configure Pathauto?
A module must be enabled and configured after installing its files.
