Is there good and detailed documentation surrounding the use of item description translations

Summary:

We are looking to make available translations of our item descriptions in various languages including German, French, Spanish all from the base English source language.

Content (required):

We noticed the translation editor that is available in PIM where we can enter and store multiple translated versions of our items for languages that we have activated. Unfortunately we do not have any documentation to describe how to utilize this data to pull them into reports, document templates, etc. We also see no way of updating this information. We are looking for some reference material related to this piece of functionality so we can make use of it.
