Ubuntu is a powerful operating system widely known for enhanced security, ease of use, full-fledged default applications, solid Ubuntu Software Center, etc, and, starting with the latest releases, for Unity.
Unity is Ubuntu's default desktop interface, that presents the user, along with a fancy launcher and a minimalistic top panel, the Dash, a good-looking overlay that houses lenses, "categories" providing numerous informations (files, folders, used applications, shops, Wikipedia-related informations, calendar appointments, graphics items, etc, informations gathered via scopes, items specialized in pushing data into lenses.
Unity -Make it yours- Lenses and Scopes for Ubuntu 12.04 LTS is an in-depth document that takes the user from the beginning to the end as related to lenses and scopes, aiming not only to merely inform the reader but also to carefully guide the interested persons in installing, managing and using lenses ("third-party" included).
The high-quality documents starts by defining lenses and scopes, and carefully plunges into, at first, the Ubuntu 12.04's default lenses, exposing with explanatory images Unity's components, such as the Ubuntu logo/BFB button, filters, search area, lens bar, as well as appropriate manners of finding and launching items (like for instance, via Dash's Global search box).
Next steps are oriented towards familiarizing the newcomer with the easy process of searching and installing (via the Dash) software exposed in the Dash but available in Ubuntu Software Center.
After explaining the default lenses step-by-step, the book shifts to a "third-party" area, where non-default lenses are presented, packed with their functionalities and methods of installations, featuring known and useful lenses, such as Unity Torrents lens, Unity Askubuntu lens, Unity Cooking lens, etc.
A probable reaction, after the user is familiarized with the presented items, is a further looking towards online and/or technical websites, links that are to be located at the ending of the user-friendly book.
The 56 pages ODT book created with LibreOffice and Shutter and edited by Charlene Tessier, Randall Ross, Daniel R. States, is available for free on launchpad
