+### 1. Counter
 
-This is a very empowering tutorial with its 13 operators covered.
+In this chapter you learn 1 of 2 operators that can count.
-Have a look into the directory `tutorials/2_scopehero/`.
+
+* `C` - Count (rate / modulo)

+### 2. Track
+
+The track lets us store a list and access its elements.
+
+* `T` - Track (index, length / list)
+
+You guessed it, using a counter you can now iterate the elements of a list
+
+### 3. Variables
+
+In this chapter you learn all the operators related to variables:
+
+* `V` - Variable, r/w single (Write: name / val | Read: - / name)
+* `K` - Kontakt, read multiple (Read: count / names)

+### 4. CakeTracker

+**Putting it all together**
+Using the values of our list (in track) as note-numbers, we are now the new-age melody heroes.   
+Enjoy the eternal bleeps of the spotless beethoven.
