Very good request. You could post this question on this thread: https://talk.maemo.org/showthread.ph...este+pre-alpha

But Maemo Leste is not yet ready and it is more for testers and those who know how to do things. Many things do not yet work and you have to know many tweaks to get things work. I'm sure that when Leste is ready for new users and public it will have good and thorough instructions how to install it. At the moment I do not think it is wise for you spend time with it. You may just get frustrated.

But maybe someone will make a thorough instructions explaining everythig in detail. I still suggest that you could drop it for now and wait untill it is made ready.
