 ## What does it do ?
 Rusteek will help you if you had to display a sentence containing data stored somewhere and data resulting from processing. 
 Let's take the BMI usecase (body mass index) to illustrate what can be done with Rusteek.
 The BMI is calculated with your height (H) and your weight (W) and the formula is : BMI = W / (H*H)
 That said, our need is to display the sentence : 
 
-"Hello ! your weight : **[WEIGHT]** kg, your height : **[HEIGHT]** meter so your BMI is **[BMI CALCULATION]**"
+> "Hello ! your weight : **[WEIGHT]** kg, your height : **[HEIGHT]** meter so your BMI is **[BMI CALCULATION]**"
 
 [WEIGHT], [HEIGHT]  are variables which we assume pre-exist somewhere and are accessible to us\
 [BMI CALCULATION] is the result of a calculation that take [WEIGHT] and [HEIGHT] as input.
 
 In Rusteek, the sentence  would be writtent like this :
 
-> Hello  **$'{'name}**, your weight : ${weight} means we dont know the value of tjhe
- 
- Hello  ${server.name}   your weight : ${weight} kg, your height : **${height}** meter so your BMI is **@calculateBMI(${weight}, ${height})**
+> Hello ! your weight : **${weight}** kg, your height : **${height}** meter so your BMI is **@calculateBMI**(**${weight}**, **${height}**)
 
 ### Variable
 In the world of "Configuration software" you can find a lot of tools to manage "placeholder".

 In this exemple, we want to set a value for the "server.name" parameter but as this may depend on a number of factor, we dont know yet this value. We use the special syntax - ${...} -  to indicate that it is a VARIALBLE that must be replaced at the right time and in the right context.
 
-That's pretty classic and if you're already familiar with the placeholder principle, good news : Ruteek work exactly the same. We won't talk about a Placeholder but about a Variable instead.
