 ### Multiline examples
 
+For multiline puzzles there are two important things:
+- **prefix** - any optional text followed by space before puzzle keyword (todo). 
+It should be the same for all lines of puzzle description.
+- \ symbol can be used to logically divide puzzle description.
+prefix should be presented with it.
+
+Examples:
+
 ```xml
 <!-- 
  ~ if comment should be started and closed by special symbols, then place them in
- ~ a separate lines without any text
- ~ Any symbol can be used as a prefix, it will be excluded from the text
+ ~ a separate lines
+ ~ Any symbol can be used as a prefix, it will be excluded from the text.
+ ~ But do not forget about the space before puzzle keyword.
  ~
- ~ @todo #34 Description can not be created in one line with comment
- ~ symbols. Just use at least the same amount of the spaces, as on the first line. 
+ ~ @todo #34 Description can be as long as needed.
+ ~  Just use at least the same amount of the spaces, as on the first line. 
+ ~  It will be added to description.
