Welcome!
Hello and welcome to Wikipedia. Thank you for your contributions. I hope you like the place and decide to stay. The following links will help you begin editing on Wikipedia:
 * The five pillars of Wikipedia
 * Contributing to Wikipedia
 * How to edit a page
 * Editing tutorial
 * Picture tutorial
 * How to write a great article
 * Naming conventions
 * Simplified Manual of Style


 * Please bear these points in mind while editing Wikipedia:
 * Respect copyrights – do not copy and paste text or images directly from other websites.
 * Maintain a neutral point of view – this is one of Wikipedia's core policies.
 * Take particular care while adding biographical material about a living person to any Wikipedia page and follow Wikipedia's Biography of Living Persons policy. Particularly, controversial and negative statements should be referenced with multiple reliable sources.
 * No edit warring or sock puppetry.
 * If you are testing, please use the Sandbox to [ do so].
 * Do not add troublesome content to any article, such as: copyrighted text, libel, advertising or promotional messages, and text that is not related to an article's subject. Deliberately adding such content or otherwise editing articles maliciously is considered vandalism; doing so will result in your account or IP being blocked from editing.
 * Do not use talk pages as discussion or forum pages as Wikipedia is not a forum.

The Wikipedia tutorial is a good place to start learning about Wikipedia. If you have any questions, see the help pages, add a question to the village pump or ask me on my talk page. By the way, you can sign your name on Talk and discussion pages using four tildes, like this: &#126;&#126;&#126;&#126; (the software will replace them with your signature and the date). Again, welcome! Noyster  (talk),  08:58, 12 August 2014 (UTC)

Copyright violation Assa Abloy
Sorry, it can't have been clear enough before. Please do not copy and paste directly from other websites - even if you give attribution. This is called "copyright violation" and is not allowed on Wikipedia. You have to write your own article based on the different sources Noyster  (talk),  18:40, 12 August 2014 (UTC)
