+HJSON is an attempt to make [JSON](https://learnxinyminutes.com/docs/json/) more human readable.
+
+HJSON is a syntax extension to JSON. 
+It's NOT a proposal to replace JSON or to incorporate it into the JSON spec itself. 
+It's intended to be used like a user interface for humans, 
+to read and edit before passing the JSON data to the machine.
+
+Let's take a look at examples to see the key syntax differences!
+
+```hjson
+{
+    # Comments are totally supported!
+    
+    // With forward slashes too!
+    
+    /*
+        Even block style comments, neat!
+    /*
+    
+    # Strings do not require quotes!
+    # Just keep it to a single line
+    human: readable
+    quotes: "are fine too"
+    
+    # Notice that commas are also not required!
+    # If using commas, strings DO require quotes!

+        with_commas: [
+            "quoted",

+            "quote"
+        ]
+        details: ["this", "is", "fine", "too"]
+    }
+    
+    # Multiline quotes with proper whitespace handling are supported!

+        I wish JSON was more human readable.
+        If only there was a JSON for my needs!
+        Oh wait.. there is! It's called HJSON.

+    
+    # Backslashes are interpretted as an escape character ONLY in quoted strings
+    slash: This will not have a new line\n

+
+    # Make sure to use quotes when mixing whitespace with important punctuation
+    example1: "If, you're, going, to, comma in a string, use, quotes!"
+    example2: "Also if you want to use {} or [] or any JSON relevant punctuation!"
