 ### @description code to detect States of Matter 
 
-## Step 1: Make temperature simulation
-
 Have you ever tried to represent the states of matter? Let's try to visually represent various states of matter based on atmospheric temperatures!

-## Step 2: Variables.
 
+## Step 1: Variables.
 
 In order for States of Matter to follow the rules for determining the  atmospheric temperature, we need to add variables that will store data. Then we will assign (set) the value of the variables. We want to name the two (2) variables as follows: “atmos_temperature” and “temperature”. Set the value of the variables to 100.  Modify your code so that your code looks like this.
