-Once we've created the model function, we can add it to the [[host]] object we created earlier, at the bottom of our code.
+The '@part' decorator marks the function defines a **model**. Inside the function, we can define which specific inputs, outputs, constants and calculations we need.
-This defines our (currently empty) model, and adds that model to our running system with the name 'Tank'.
+The human readable name for our model is 'Online Tank Model'.

 For example, the function here will be...
-<code>(LevelPerc.num() / 100) * Capacity.num()</code>
+<code>(float(LevelPerc) / 100) * float(Capacity)</code>
-//Note that the 'num' function converts a DataPoint to a floating-point number. Some points will be strings, so it's important to always cast the value to a number if you're using it as one.//.
+//Note that data points aren't simple numbers - you'll need to cast them to floats or integers if you want to use them as numeric values. If you need to access the raw value, use **.value**.//.
