+Problem Builder Usage
+=====================
+
+When you add the **Problem Builder** component to a course in the studio, the
+built-in editing tools guide you through the process of configuring the block
+and adding individual questions.
+
+See [Question Types](Questions.md) to learn about the various types of question
+that can be added to a Problem Builder block.
+
+
+Configuration Options
+---------------------
+
+### Maximum Attempts
+
+You can limit the number of times students are allowed to complete a
+Mentoring component by setting the **Max. attempts allowed** option.
+
+Before submitting an answer for the first time:
+
+![Max Attempts Before](img/max-attempts-before.png)
+
+After submitting a wrong answer two times:
+
+![Max Attempts Reached](img/max-attempts-reached.png)
+
+### Custom Window Size for Tip Popups
+
+You can specify **Width** and **Height** attributes of any Tip
+component to customize the popup window size. The value of those
+attributes should be valid CSS (e.g. `50px`).

+Questions and Other Components
+==============================
+
+These are the types of questions that can be added to Problem Builder and Step
+Builder:
+
+
+### Free-form Questions
+
+Free-form questions are represented by a **Long Answer** component.
+
+Example screenshot before answering the question:
+
+![Answer Initial](img/answer-1.png)
+
+Screenshot after answering the question:
+
+![Answer Complete](img/answer-2.png)
+
+You can add **Long Answer Recap** components to problem builder blocks later on
+in the course to provide a read-only view of any answer that the student entered
+earlier.
+
+The read-only answer is rendered as a quote in the LMS:
+
+![Answer Read-Only](img/answer-3.png)
+
+### Multiple Choice Questions (MCQs)
+
+Multiple Choice Questions can be added to a problem builder component and have
+the following configurable options:
+
+* **Question** - The question to ask the student
+* **Message** - A feedback message to display to the student after they have
+  made their choice.
+* **Weight** - The weight is used when computing total grade/score of the
+  problem builder block. The larger the weight, the more influence this question
+  will have on the grade. Value of zero means this question has no influence on
+  the grade (float, defaults to `1`).
+* **Correct Choice[s]** - Specify which choice[s] are considered correct. If a
+  student selects a choice that is not indicated as correct here, the student
+  will get the question wrong.
+
+Using the Studio editor, you can add **Custom Choice** blocks to an MCQ. Each
+Custom Choice represents one of the options from which students will choose
+their answer.
+
+You can also add **Tip** entries. Each Tip must be configured to link it to one
+or more of the choices. If the student selects a choice, the tip will be
+displayed.

+![MCQ Success](img/mcq-3.png)
+
+#### Rating Questions
+
+When constructing questions where the student rates some topic on the scale from
+`1` to `5` (e.g. a Likert Scale), you can use the Rating question type, which
+includes built-in numbered choices from 1 to 5. The `Low` and `High` settings
+specify the text shown next to the lowest and highest valued choice.
+
+Rating questions are a specialized type of MCQ, and the same instructions apply.
+You can also still add **Custom Choice** components if you want additional
+choices to be available such as "I don't know".
+
+### Multiple Response Questions (MRQs)
+
+Multiple Response Questions are set up similarly to MCQs. The answers are
+rendered as checkboxes. Unlike MCQs where only a single answer can be selected,
+MRQs allow multiple answers to be selected at the same time.
+
+MRQ questions have these configurable settings:
+
+* **Question** - The question to ask the student
+* **Required Choices** - For any choices selected here, if the student does
+  *not* select that choice, they will lose marks.
+* **Ignored Choices** - For any choices selected here, the student will always
+  be considered correct whether they choose this choice or not.
+* Message - A feedback message to display to the student after they have made
+  their choice.
+* **Weight** - The weight is used when computing total grade/score of the
+  problem builder block. The larger the weight, the more influence this question
+  will have on the grade. Value of zero means this question has no influence on
+  the grade (float, defaults to `1`).
+* **Hide Result** - If set to `True`, the feedback icons next to each choice
+  will not be displayed (This is `False` by default).
+
+The **Custom Choice** and **Tip** components work the same way as they do when
+used with MCQs (see above).

+
+Other Components
+================
+
+### Tables
+
+Tables allow you to present answers to multiple free-form questions in a concise
+way. Once you create an **Answer Recap Table** inside a Mentoring component in
+Studio, you will be able to add columns to the table. Each column has an
+optional **Header** setting that you can use to add a header to that column.
+Each column can contain one or more **Answer Recap** elements, as well as HTML
+components.
