+############################
 
-The format for edX problems is based on the `LONCAPA XML format`_,
-although the two are not quite compatible. In the edX variant, problems are
-composed of four types of tags:
+Use the chapters in this section to understand how to create exercises and
+tools in your course.
 
-* **inputtypes** are similar to XBlocks. They define ways for users to enter
-  input into the problem.
-* **responsetypes** are graders. They define how inputs are mapped to grades. 
-* **hinters** are used to provide feedback to problems. 
-* Standard HTML tags are used for formatting. 
+For information on how to develop your course content in the Studio Outline
+page, see :ref:`Developing Your Course Index`.
 
-OLX is designed to allow mixing-and-matching of inputtypes,
-responsetypes, and hinters. For example, a numerical grader could match
-7+-0.1%. It would be okay to use this with any inputtype which output a number,
-whether this was a text box, equation input, slider, or multiple choice
-question. In practice, this doesn't always work. For example, in the former
-case, a multiple choice question would not give an output in a format a
-numerical grader could handle.
+For information on building specific course component types, see :ref:`Creating
+Course Content Index`.
 
-In addition, in many cases, there is a 1:1 mapping between graders and inputs.
-For some types of inputs (especially discipline-specific specialized ones), it
-simply does not make sense to have more than one grader.
-
-The most general grader is ``customresponse``. This uses Python code
-to evaluate the input. By design, this ought to work with any inputtype,
-although there are bugs mixing this with a small number of the newer
-inputtypes.
-
-Like LON-CAPA, OLX allows embedding of code to generate parameterized problems.
-Unlike LON-CAPA, edX supports Python (and not Perl). Otherwise, the syntax is
-approximately identical.
