+#Documentation
+
+Documentation is an important part of writing software. Learning how to properly read and write documentation is almost as important as being able to write the actual programming language. 
+
+### RDOC tests
+
+1 As a student I know how to create a comment so that I can make explain my code properly
+
+2 As a beginner programmer I know how to read RDOC comments to identify the return value of a method so I can understand what a method will return.
+
+3 As a beginner programmer I know how to read RDOC comments to identify the input value of a method so I can understand what parameters a method expects.

+### Stories are ideas. 
+
+When you're writing a story remember that it will need to be understandable by both the students, the teacher and the developer writing the test.
+
+We use an adoptation of traditional [Agile user stories][1] that stories should be short, from your own perspective, easy to read and understand. Most importantly to learning coding, stories should explain the value of learning a particular concept.
+
+Commonly, user stories follow the format below:
+
+```As a <type of user>, I want <some goal> so that <some reason>.```
+
+A realistic example:
+
+```As a beginner ruby programmer I want to write syntaxtually correct Ruby code so that I can learn how be a good developer.```

+
+### Basic math
+MATH1 As a beginner programmer I should be able to add numbers together so that I understand how ruby can be used to add numbers.
+
+MATH2 As a beginner programmer I should be able to subtract numbers so that I understand how ruby can be used to subtract numbers.
+
+MATH3 As a beginner programmer I should be able to multiply numbers so that I understand how ruby can be used to multiply numbers.
+
+MATH4 As a beginner programmer I should be able to divide numbers so that I understand how ruby can be used to multiply numbers.

+### Tests shouldn't be hard
+
+Tests should be written to determine if a particular set of stories have been satisfied. Tests are used to prove if a student has correctly coded an element of an assignment. As students progress, their assignments will be exposed to more tests.
+
+### Assigning tests to stories
+
+Test documentation should be correctly associated with a test. Remember that the tests can be run locally by students and by teachers to grade assignments.
