This is the main project for all Drupal documentation, except contributed projects. For contributed projects create an issue in the issue queue for that project.
To learn more about helping with documentation efforts, start with the Contribute to documentation section of the handbook.
The Creative Commons module allows users to select and assign a Creative Commons license to a node and any attached content, or to the entire site. It also provides integration between CC and Drupal technology.
The Pathauto module automatically generates URL/path aliases for various kinds of content (nodes, taxonomy terms, users) without requiring the user to manually specify the path alias. This allows you to have URL aliases like /category/my-node-title instead of /node/123. The aliases are based upon a "pattern" system that uses tokens which the administrator can change.
The module allows parent-child relationships between nodes to be established, managed and searched. You can restrict the types of nodes that can be parented and the ordinality of parents.
