If you are new to Drupal, you will want to learn more about Drupal issue queues.
Drupal Commerce is an actively maintained project, and oftentimes you'll be able to search its Issue Queue to find an answer to a question or a solution to a problem/bug. Solutions are usually presented in the form of a patch. See the Patching section of this documentation guide for information about applying patches.
Drupal Answers is a question and answer site for Drupal developers and administrators. To search for information specific to Drupal Commerce, tag your queries with
