Joomla reconstruction, creating own mod

MVC model not clear

[OrlandoM]

Hello to everyone, how can I configure Joomla to work with my own modules? Where I can read more detailed about MVC model? I've read their "Hello world", but don't catch the main advantage of MVC, maybe someone has read more complicated tutorials? When enabling other mods why they are displayed on the left nav bar instead of where main text goes, maybe, fixing HTML helps me?
And one more question is there a guide how to write own template?

This should help you with the template creation or at least point you in the right direction. [docs.joomla.org...]

Best way to make a module and make it fit anywhere is to use the Jumi extension. You then embed the code and put it in any position you want, if no positions exist you make one.
