A new guide for newbies

Hello Everyone. I am a newbie, and unfortunately, have been a newbie for a very long time now. The two biggest hurdles that are stopping me from making any progress are 1. I am afraid I might break something 2. I can't figure out where I can fit in the docs team. To solve the first problem, I want to ask if it is possible to start a "Hello World" doc: A doc meant exclusively for newbies, that never gets published for any release, where everyone is welcome to jump in and get comfortable with the process without worrying about breaking something. Every newbie who joins can be asked to create a chapter in his name, where he can post information about himself, what he likes to work on, and to say "hello world". This will be a good place to get familiar with the system. Further, the doc can be about the process, where to start, what tools to use and all instructions that a newbie will need. This will have the added bonus that a newbie who reads it and doesn't understand something will be able to correct it from his own experience, without bothering everyone else. Taking this one step further, this doc can also act as a guinea pig for all changes in the publishing process. In the current discussions about the QA process, a suggestion was put forward to try out a new method on one doc and see if it scales up. This can be the guide to be experimented upon for all such trials. Can this be done? --Dilip
