+## \-\-- Day 12: JSAbacusFramework.io \-\--
+
+Santa\'s Accounting-Elves need help balancing the books after a recent
+order. Unfortunately, their accounting software uses a peculiar storage
+format. That\'s where you come in.
+
+They have a [JSON](http://json.org/) document which contains a variety
+of things: arrays (`[1,2,3]`), objects (`{"a":1, "b":2}`), numbers, and
+strings. Your first job is to simply find all of the *numbers*
+throughout the document and add them together.
+
+For example:
+
+-   `[1,2,3]` and `{"a":2,"b":4}` both have a sum of `6`.
+-   `[[[3]]]` and `{"a":{"b":4},"c":-1}` both have a sum of `3`.
+-   `{"a":[-1,1]}` and `[-1,{"a":1}]` both have a sum of `0`.
+-   `[]` and `{}` both have a sum of `0`.
+
+You will not
+encounter
+any strings containing numbers.
+
+What is the *sum of all numbers* in the document?
+
+Your puzzle answer was `191164`.
+
+The first half of this puzzle is complete! It provides one gold star: \*
+
+## \-\-- Part Two \-\-- {#part2}
+
+Uh oh - the Accounting-Elves have realized that they double-counted
+everything *red*.
+
+Ignore any object (and all of its children) which has any property with
+the value `"red"`. Do this only for objects (`{...}`), not arrays
+(`[...]`).
+
+-   `[1,2,3]` still has a sum of `6`.
+-   `[1,{"c":"red","b":2},3]` now has a sum of `4`, because the middle
+    object is ignored.
+-   `{"d":"red","e":[1,2,3,4],"f":5}` now has a sum of `0`, because the
+    entire structure is ignored.
+-   `[1,"red",5]` has a sum of `6`, because `"red"` in an array has no
+    effect.
+
+Answer:
+
+Although it hasn\'t changed, you can still [get your puzzle
+input](12/input).
