+Examples for Developers
+=======================
+
+http://drupal.org/project/examples
+
+What Is This?
+-------------
+
+This set of modules is intended to provide working examples of Drupal's
+features and APIs.  The modules strive to be simple, well documented and
+modification friendly, in order to help developers quickly learn their inner
+workings.
+
+These examples are meant to teach you about code-level development for Drupal
+7. Some solutions might be better served using a contributed module, so that
+you don't end up having to re-invent the wheel in PHP.
+
+
+How To Use The Examples
+-----------------------
+
+There are three main ways to interact with the examples in this project:
+
+1. Enable the modules and use them within Drupal. Not all modules will have
+obvious things to see within Drupal. For instance, while the Page and Form API
+examples will show you forms, the Database API example will not show you much
+within Drupal itself.
+
+2. Read the code. Much effort has gone into making the example code readable,
+not only in terms of the code itself, but also the extensive inline comments
+and documentation blocks.
+
+3. Browse the code and documentation on the web. There are two main places to
+do this:
+
+* https://api.drupal.org/api/examples is the main API site for all of Drupal.
+It has all manner of cross-linked references between the example code and the
+APIs being demonstrated.
+
+* http://drupalcode.org/project/examples.git allows you to browse the git
+repository for the Examples project.
+
+
+How To Install The Modules
+--------------------------
+
+1. Install Examples for Developers (unpacking it to your Drupal
+/sites/all/modules directory if you're installing by hand, for example).
+
+2. Enable any Example modules in Admin menu > Site building > Modules.
+
+3. Rebuild access permissions if you are prompted to.
+
+4. Profit!  The examples will appear in your Navigation menu (on the left
+sidebar by default; you'll need to reenable it if you removed it).
+
+Now you can read the code and its comments and see the result, experiment with
+it, and hopefully quickly grasp how things work.
+
+If you find a problem, incorrect comment, obsolete or improper code or such,
+please search for an issue about it at http://drupal.org/project/issues/examples
+If there isn't already an issue for it, please create a new one.
