 null vs undefined in JSON

-Since it is not valid to set `undefined` in JSON, calling `db.set('x')` is the same as `db.remove('x')`.
+These notes do not reflect a bugs or defects in this library,
+they're simply to inform you of a few 'gotchas' inherent in JSON / DOMStorage conversion.
 
-However, `null`, and `"null"` both parse as `null` the "object", but the string (which would be `"\"null\""`).
+99.999% of the time these gotchas shouldn't effect you in any way.
+If they do, you're probably doing something wrong in the first place.
 
-Therefore, setting a key to `undefined` will remove it from the db, but setting it to `null` will save it.
 
-Yet both values that exist as `null` and values that don't exist will return `null`.
+It is not valid to set `undefined` in JSON. So setting a key to `undefined` will remove it from the db.
 
-Also `{ "foo": null, "bar": "null" }` will parse as `foo` being `null` but `bar` being `"null"`, much unlike the value `"null"` being parsed on its own.
+This means that `db.set('x')` is the same as `db.remove('x')`.
+
+To save `undefined`, use `null` instead.
+
+
+Note that both values that exist as `null` and values that don't exist at all will return `null`.

+    db.set('existing-key', null);
+    null === db.get('existing-key');
+    null === db.get('non-existant-key');

+The special case of `null` as `"null"`, aka `"\"null\""`:
+
+`null`, and `"null"` both parse as `null` the "object", instead of one being the string (which would be `"\"null\""`).
+
+Objects containing `null`, however, parse as expected `{ "foo": null, "bar": "null" }` will parse as `foo` being `null` but `bar` being `"null"`, much unlike the value `"null"` being parsed on its own.
