### URLs You Can Memorize!

copyleft.org has many easy-to-remember URLs.  These are convenience URLs that

you can memorize and give to people verbally to point them to the right part

of [The Guide](https://copyleft.org/guide/).  (Since the guide is very large,

we thought a few easy-to-remember ways to tell people where to look would be

helpful.)  Here are the primary ones:

  * [copyleft.org](https://copyleft.org) points to this page.

  * [copyleft.guide](http://copyleft.guide) points to the guide itself.

  * [compliance.guide](http://compliance.guide) points to the *GPL Compliance Guide* section of the full Guide.

  * [gpl.guide](http://gpl.guide) points to the *Detailed Analysis of the GNU GPL and Related Licenses* section of the full Guide.

As time goes on, we'll add convenience URLs to refer to specific parts of the

guide, which makes it easy to refer people to portions of the Guide.  Here

are a the ones that exist so far:

  * [compliance.guide/pristine](http://compliance.guide/pristine) points to

    the "pristine example", the chapter entitled *ThinkPenguin Wireless Router: Excellent CCS*.
