+json11
+------
+
+json11 is a tiny JSON library for C++11, providing JSON parsing and serialization.
+
+The core object provided by the library is json11::Json. A Json object represents any JSON
+value: null, bool, number (int or double), string (std::string), array (std::vector), or
+object (std::map).
+
+Json objects act like values. They can be assigned, copied, moved, compared for equality or
+order, and so on. There are also helper methods Json::dump, to serialize a Json to a string, and
+Json::parse (static) to parse a std::string as a Json object.
+
+It's easy to make a JSON object with C++11's new initializer syntax:
+
+    Json my_json = Json::object {
+        { "key1", "value1" },
+        { "key2", false },
+        { "key3", Json::array { 1, 2, 3 } },
+    };
+    std::string json_str = my_json.dump();
+
+There are also implicit constructors that allow standard and user-defined types to be
+automatically converted to JSON. For example:
+
+    class Point {
+    public:
+        int x;
+        int y;
+        Point (int x, int y) : x(x), y(y) {}
+        Json to_json() const { return Json::array { x, y }; }
+    };
+
+    std::vector<Point> points = { { 1, 2 }, { 10, 20 }, { 100, 200 } };
+    std::string points_json = Json(points).dump();
+
+JSON values can have their values queried and inspected:
+
+    Json json = Json::array { Json::object { { "k", "v" } } };
+    std::string str = json[0]["k"].string_value();
+
+More documentation is still to come. For now, see json11.hpp.
