title: Understanding Impex Syntax Statement in Hybris
body: <p>Hello I'm trying to learn Hybris and since I don't have access to Wiki site its difficult for me to understand the basics behind the code. Can someone please help me understand the below Impex statements for a text "Welcome to home page" in the home page. </p>
  
  <p>My questions from the below code are ; actually, I have more but don't want to put burden but if you can help me in most basics of Impex statement I will greatly appreciate it.  </p>
  
  <p>1) In some place more than one semicolon is used, why?<br>
  2) What is uid?<br>
  3) It seems values of parameters defined in starts begins after two semicolons (;;) in each statement, let me know I'm correct?</p>
