+# Renderable JSON Format
+This covers the JSON format this library expects in order to properly render Parsons Problems
+
+## Status
+- Draft | Proposed | Final (pick one)
+- Version: 0.1.0
+- Last updated: YYYY-MM-DD
+
+## Table of contents
+- Overview

+
+## Overview
+Explain what this format represents, intended consumers, and high-level constraints.
+
+## Format / Schema
+
+### Top Level Schema
+
+Example skeleton:
+```json
+{
+    "question_text": "",
+    "options": {},
+    "blocks": []
+}
+```
+
+## Fields
+
+### Question Text
+The instructions for for the exercise
+
+key : `"question_text"`  <br>
+type: string
+
+### Options
+Contains the configuration of features necessary for the proper rendering of the Parsons Problem
+
+key : `"options"` <br>
+type : map
+
+```json
+{
+    "grader": {
+        "type": "dag",
+        "show_feedback": true
+    },
+    "maxdist": 0,
+    "indent": {
+        "active":true,
+        "mode":"", // prescribed or free
+        "max_indents":3 //Defaults to 3 if not specified
+    },
+    "adaptive": true,
+    "numbered": false,
+    "language": "math"
+}
+```
+-  `"grader"`
+    - Types are `dag` for order-graded exercises and `execute` for execution-based assignments
+    - Show Feedback is booloean to determine whether students get feedback after checking their answer
+- `"maxdist"` macimum number of distractors allowed. (Deprecated)
+- `"indent"`
+    - `active`: Boolean. If false, the `mode` and `max_indents` should not be provided.
+    - `mode`: String. Options are `prescribed` and `free`.
+        - `free` will not allow block level indent specifications. Block level indent specifications should be ignored if present. Users should be allowed to indent blocks as they wish. Two main use cases are: exercises that allow indentation but do not rely on the indents for correctness; execution-based exercises.
+        - `prescribed` requires all blocks to include an `"indent"` key for specifying its correct indent level. This is especially useful for grading order-graded exercises that have indents.
+    - `max_indents`: Number. The number of indent levels to be provided to the user. The **default** value will be set to 3 if not specified.
+       
+- `"adaptive"`: Boolean. Is it an adaptive parsons problem or not. This is `true` by **default**
+- `"numbered"`: Boolean. Attaches numbers to the blocks when set to **true**
+- `"language"`: String. Determines how the block text is displayed. It may also determine how code is extracted for execution provided the language has certain quirks. Supported options are:
+    - `"math'`, `"natural"` - Renders text as if it were Git Flavored Markdown and handles latex. This should be the default mode.
+    - `"python"`, `"java"`, `"javascript"`, `"html"`, `"c"`, `"c++"`, `"cpp"`,`"ruby"`.
+
+<!-- - `"runnable"`: DEPRECATED, should go. -->
+
+### Blocks
+Contains the list of blocks to be displayed.
+
+key : `"blocks"`  <br>
+type: []blocks (list of blocks)
+
+Structure of a block:
+```json
+{
+    "text": "",
+    "type": "",
+    "tag": "fixed",
+    "depends": "",
+    "indent": "",
+    "displaymath": true,
+    "feedback": ""
+}
+```
+
+
+## Examples
+Full example:
+```json

+    - required: no  
+    - options: "distractor", "fixed", "toggle", "textbox"  
+    - notes: Defines the type of block.

+- tag

+    - required: no
+    - example: any unique string
+    - notes: Identifier used by depends to describe correct orderings
+
+- depends  
+    - type: string or array[string]  
+    - required: yes, for order-grading only
+    - example: "randomg1b1" or ["a","b"]
