+### Arbitrary types conversions
+
+Every type can be serialized in JSON, not just STL-containers and scalar types. Usually, you would do something along those lines:
+
+```cpp
+namespace ns {
+    // a simple struct to model a person
+    struct person {
+        std::string name;
+        std::string address;
+        int age;
+    };
+}
+
+ns::person p = {"Ned Flanders", "744 Evergreen Terrace", 60};
+
+// convert to JSON: copy each value into the JSON object
+json j;
+j["name"] = p.name;
+j["address"] = p.address;
+j["age"] = p.age;
+
+// ...
+
+// convert from JSON: copy each value from the JSON object
+ns::person p {
+    j["name"].get<std::string>(),
+    j["address"].get<std::string>(),
+    j["age"].get<int>()
+};
+```
+
+It works, but that's quite a lot of boilerplate... Fortunately, there's a better way:
+
+```cpp
+// create a person
+ns::person p {"Ned Flanders", "744 Evergreen Terrace", 60};
+
+// conversion: person -> json
+json j = p;
+
+std::cout << j << std::endl;
+// {"address":"744 Evergreen Terrace","age":60,"name":"Ned Flanders"}
+
+// conversion: json -> person
+ns::person p2 = j;
+
+// that's it
+assert(p == p2);
+```
+
+#### Basic usage
+
+To make this work with one of your types, you only need to provide two functions:
+
+```cpp
+using nlohmann::json;
+
+namespace ns {
+    void to_json(json& j, const person& p) {
+        j = json{{"name", p.name}, {"address", p.address}, {"age", p.age}};
+    }
+
+    void from_json(const json& j, person& p) {
+        p.name = j["name"].get<std::string>();
+        p.address = j["address"].get<std::string>();
+        p.age = j["age"].get<int>();
+    }
+} // namespace ns
+```
+
+That's all! When calling the `json` constructor with your type, your custom `to_json` method will be automatically called.
+Likewise, when calling `get<your_type>()`, the `from_json` method will be called.
+
+Some important things:
+
+* Those methods **MUST** be in your type's namespace (which can be the global namespace), or the library will not be able to locate them (in this example, they are in namespace `ns`, where `person` is defined).
+* When using `get<your_type>()`, `your_type` **MUST** be [DefaultConstructible](http://en.cppreference.com/w/cpp/concept/DefaultConstructible). (There is a way to bypass this requirement described later.)
+
+#### How do I convert third-party types?
+
+This requires a bit more advanced technique. But first, let's see how this conversion mechanism works:
+
+The library uses **JSON Serializers** to convert types to json.
+The default serializer for `nlohmann::json` is `nlohmann::adl_serializer` (ADL means [Argument-Dependent Lookup](http://en.cppreference.com/w/cpp/language/adl)).
+
+It is implemented like this (simplified):
+
+```cpp
+template <typename T>
+struct adl_serializer {
+    static void to_json(json& j, const T& value) {
+        // calls the "to_json" method in T's namespace
+    }
+
+    static void from_json(const json& j, T& value) {
+        // same thing, but with the "from_json" method
+    }
+};
+```
+
+This serializer works fine when you have control over the type's namespace. However, what about `boost::optional`, or `std::filesystem::path` (C++17)? Hijacking the `boost` namespace is pretty bad, and it's illegal to add something other than template specializations to `std`...
+
+To solve this, you need to add a specialization of `adl_serializer` to the `nlohmann` namespace, here's an example:
+
+```cpp
+// partial specialization (full specialization works too)
+namespace nlohmann {
+    template <typename T>
+    struct adl_serializer<boost::optional<T>> {
+        static void to_json(json& j, const boost::optional<T>& opt) {
+            if (opt == boost::none) {
+                j = nullptr;
+            } else {
+              j = *opt; // this will call adl_serializer<T>::to_json which will
+                        // find the free function to_json in T's namespace!
+            }
+        }
+
+        static void from_json(const json& j, boost::optional<T>& opt) {
+            if (j.is_null()) {
+                opt = boost::none;
+            } else {
+                opt = j.get<T>(); // same as above, but with 
+                                  // adl_serializer<T>::from_json
+            }
+        }
+    };
+}
+```
+
+#### How can I use `get()` for non-default constructible/non-copyable types?
+
+There is a way, if your type is [MoveConstructible](http://en.cppreference.com/w/cpp/concept/MoveConstructible). You will need to specialize the `adl_serializer` as well, but with a special `from_json` overload:
+
+```cpp
+struct move_only_type {
+    move_only_type() = delete;
+    move_only_type(int ii): i(ii) {}
+    move_only_type(const move_only_type&) = delete;
+    move_only_type(move_only_type&&) = default;
+    
+    int i;
+};
+
+namespace nlohmann {
+    template <>
+    struct adl_serializer<move_only_type> {
+        // note: the return type is no longer 'void', and the method only takes
+        // one argument
+        static move_only_type from_json(const json& j) {
+            return {j.get<int>()};
+        }
+        
+        // Here's the catch! You must provide a to_json method! Otherwise you
+        // will not be able to convert move_only_type to json, since you fully
+        // specialized adl_serializer on that type
+        static void to_json(json& j, move_only_type t) {
+            j = t.i;
+        }
+    };
+}
+```
+
+#### Can I write my own serializer? (Advanced use)
+
+Yes. You might want to take a look at [`unit-udt.cpp`](https://github.com/nlohmann/json/blob/develop/test/src/unit-udt.cpp) in the test suite, to see a few examples.
+
+If you write your own serializer, you'll need to do a few things:
+
+* use a different `basic_json` alias than `nlohmann::json` (the last template parameter of `basic_json` is the `JSONSerializer`)
+* use your `basic_json` alias (or a template parameter) in all your `to_json`/`from_json` methods
+* use `nlohmann::to_json` and `nlohmann::from_json` when you need ADL
+
+Here is an example, without simplifications, that only accepts types with a size <= 32, and uses ADL.
+
+```cpp
+// You should use void as a second template argument
+// if you don't need compile-time checks on T
+template<typename T, typename SFINAE = typename std::enable_if<sizeof(T) <= 32>::type>
+struct less_than_32_serializer {
+    template <typename BasicJsonType>
+    static void to_json(BasicJsonType& j, T value) {
+        // we want to use ADL, and call the correct to_json overload
+        using nlohmann::to_json; // this method is called by adl_serializer,
+                                 // this is where the magic happens
+        to_json(j, value);
+    }
+    
+    template <typename BasicJsonType>
+    static void from_json(const BasicJsonType& j, T& value) {
+        // same thing here
+        using nlohmann::from_json;
+        from_json(j, value);
+    }
+};
+```
+
+Be **very** careful when reimplementing your serializer, you can stack overflow if you don't pay attention:
+
+```cpp
+template <typename T, void>
+struct bad_serializer
+{
+    template <typename BasicJsonType>
+    static void to_json(BasicJsonType& j, const T& value) {
+      // this calls BasicJsonType::json_serializer<T>::to_json(j, value);
+      // if BasicJsonType::json_serializer == bad_serializer ... oops!
+      j = value;
+    }
+    
+    template <typename BasicJsonType>
+    static void to_json(const BasicJsonType& j, T& value) {
+      // this calls BasicJsonType::json_serializer<T>::from_json(j, value);
+      // if BasicJsonType::json_serializer == bad_serializer ... oops!
+      value = j.template get<T>(); // oops!
+    }
+};
+```
+
 ### Binary formats (CBOR and MessagePack)
 
 Though JSON is a ubiquitous data format, it is not a very compact format suitable for data exchange, for instance over a network. Hence, the library supports [CBOR](http://cbor.io) (Concise Binary Object Representation) and [MessagePack](http://msgpack.org) to efficiently encode JSON values to byte vectors and to decode such vectors.
