Please help me understand blueprint

Hey everybody 

no matter how hard I try I cannot get my head around blueprint. 

All I want to do is to have states 

I want tasks created and completed in between states as transitions. 

Example: 

not qualified 

Task: phone client 
auto email: welcome to my company

client contacted 

auto send client booking email 
call client to confirm meeting booking 

meeting booked 

convert to deal
