hi
i am trying to open my new website although i dont know much abt coding or any sort of other stuffs. google tutorials and help from forums are my main help source  

i was looking for a good CMS system and while i was looking around i found this site. looked around a bit and liked it. so i have installed it in my hosting

i am pretty familiar with the forum options as i have already used them in other forums but i have trouble understanding the home page block options. how do i create and modify a block is a mystery to me. although i think i know how to create a block but how to modify a block, what files to modify how to add texts and colors and other stuffs is something i really dont get.  
i was looking around for any previous post (perhaps tutorials) for doing those (i.e. modify and create blocks) but i couldn't find any. maybe there is but i wasnt being able to find them out or they were too complicated for me to understand  
so will anyone help me here on how to modify or create blocks in a simple and easy way? or if there is already an understandable tutorial kindly paste the url here
 thanks in advance
