+For an "until" loop, this loops the program until the specified condition becomes true.

 '''Test the loop at the:'''
-Select whether you wish the loop to be tested at the start or at the end of the loop.
+Select whether you wish the loop's expression to be tested at the start or at the end of the loop. Testing at the end of the loop means that the code within the loop is guaranteed to execute at least once.
 '''Loop count'''
-Sets the loop to loop through a set number of times.
+Sets the loop to loop through a set number of iterations. The value should usually be a whole number between 1 and 99999999.
-Count must be a whole number between 1 and 99999999.
+Note that a variable can be used for the "count" rather than a constant value. But be aware because changing the value of this variable within the loop could cause odd behaviour and make your program's execution difficult to predict.
 '''Count using a variable'''
-Allows one of your existing variables to be used as the count variable.
+Allows an existing variable to be used as the count variable. When active, this resets the count variable to 0 when the loop first begins and automatically increments the variable at the end of each loop iteration. It is best that the value of this variable should not be altered within the loop by user code, otherwise the loop may behave unexpectedly.
