Codebook

A codebook is a book, like a photo story book, depicting code snippets on each side of a page. These code snippets can be a hook_form_alter() or an implementation of hook_mail(). A developer can create her/his codebook and can share those code snippets to other developers. Developers can keep a code snippet of the codebook private until the code snippet is ready to be used. Developers can collaborate in testing and evaluating the snippet in the codebook.

Now, what code snippets should be included in the codebook?
Well, of course! Drupal, eh?

A developer should include code snippets related to Drupal only. The reason is, this site is aimed to provide a guidance to Drupal developers. So, adding any other code is strongly discouraged and will be removed from the Developer's network.

Your codebook can be used as reference by newbies and this may help other developers as well in designing their sites.
