+## Random Number
+
+Random nubmers can be used to do countdowns or other things that are needed. 
+To get a random number, you have to import the randomint class from the random library 
+by adding 
+
+```
+from random import randint
+```
+
+to the top of your Python script. 
+
+Then you can set the random integer to a variable by doing 
+
+```
+myNumber = randint(5,60)
+```
+
+In the example above, 5 is the lower limit of the range and 60 is the upper limit
+of the range. If your range needs to be different, then changes either or both of 
+these values.
