-ArduinoJsonParser change log
-============================
+Arduino JSON: change log
+========================
+
+v4.0
+----
+
+* Unified parser and generator API (issue #23)
+* Updated library layout, now requires Arduino 1.0.6 or newer
+
+**BREAKING CHANGE**: API changed significantly, see `doc/Migrating to the new API.md`.
+
+
+v3.4
+----
+
+* Fixed escaped char parsing (issue #16)
+  
+
+v3.3
+----
+
+* Added indented output for the JSON generator (issue #11), see example bellow.
+* Added `IndentedPrint`, a decorator for `Print` to allow indented output
+
+Example:
+
+    JsonOject<2> json;
+    json["key"] = "value";
+    json.prettyPrintTo(Serial);
+
+v3.2
+----
+
+* Fixed a bug when adding nested object in `JsonArray` (bug introduced in v3.1).
+
+v3.1
+----
+
+* Calling `Generator::JsonObject::add()` twice with the same `key` now replaces the `value`
+* Added `Generator::JsonObject::operator[]`, see bellow the new API
+* Added `Generator::JsonObject::remove()` (issue #9)
+
+Old generator API:
+
+	JsonObject<3> root; 
+    root.add("sensor", "gps");
+    root.add("time", 1351824120);
+    root.add("data", array);
+
+New generator API:
+
+	JsonObject<3> root; 
+    root["sensor"] = "gps";
+    root["time"] = 1351824120;
+    root["data"] = array;
+
+v3.0
+----
+
+* New parser API, see bellow
+* Renamed `JsonHashTable` into `JsonObject`
+* Added iterators for `JsonArray` and `JsonObject` (issue #4)
+
+Old parser API:
+
+    JsonHashTable root = parser.parseHashTable(json);
+
+	char*  sensor    = root.getString("sensor");
+	long   time      = root.getLong("time");
+	double latitude  = root.getArray("data").getDouble(0);
+    double longitude = root.getArray("data").getDouble(1);
+
+New parser API:
+
+	JsonObject root = parser.parse(json);
+
+	char*  sensor    = root["sensor"];
+    long   time      = root["time"];
+    double latitude  = root["data"][0];
+    double longitude = root["data"][1];
+
+v2.1
+----
+
+* Fixed case `#include "jsmn.cpp"` which caused an error in Linux (issue #6)
+* Fixed a buffer overrun in JSON Parser (issue #5)
+
+v2.0
+----
+
+* Added JSON encoding (issue #2)
+* Renamed the library `ArduinoJsonParser` becomes `ArduinoJson`
+
+**Breaking change**: you need to add the following line at the top of your program.
+
+	using namespace ArduinoJson::Parser;
+
+v1.2
+----
+
+* Fixed error in JSON parser example (issue #1)
 
 v1.1
 ----
 
-* Example: changed `char* json` into `char json[]` so that the byes are not write protected
+* Example: changed `char* json` into `char[] json` so that the bytes are not write protected
 * Fixed parsing bug when the JSON contains multi-dimensional arrays
 
 v1.0

-An efficient JSON parser for Arduino
-====================================
+Arduino JSON library
+====================
 
-This library is an thin C++ wrapper around the *jsmn* tokenizer: http://zserge.com/jsmn.html
+[![Build Status](https://travis-ci.org/bblanchon/ArduinoJson.svg?branch=master)](https://travis-ci.org/bblanchon/ArduinoJson)
 
-It's design to be very lightweight, works without any allocation on the heap (no malloc) and supports nested objects.
+*An elegant and efficient JSON library for embedded systems.*
 
-It has been written with Arduino in mind, but it isn't linked to Arduino libraries so you can use this library on any other C++ project.
+It's design to have the most intuitive API, the smallest footprint and works without any allocation on the heap (no malloc).
 
+It has been written with Arduino in mind, but it isn't linked to Arduino libraries so you can use this library in any other C++ project.
 
 Features
 --------
 
-* Based on the well-proven [jsmn](http://zserge.com/jsmn.html) tokenizer
-* Supports nested objects
-* Works with fixed memory allocation : no `malloc()`
-* Low footprint
+* JSON decoding
+* JSON encoding (with optional indentation)
+* Elegant API, very easy to use 
+* Fixed memory allocation (no malloc)
+* Small footprint
 * MIT License
 
+Quick start
+-----------
 
-Example
--------
-
-    char json[] = "{\"Name\":\"Blanchon\",\"Skills\":[\"C\",\"C++\",\"C#\"],\"Age\":32,\"Online\":true}";
-
-    JsonParser<32> parser;
-
-    JsonHashTable hashTable = parser.parseHashTable(json);
-
-    if (!hashTable.success())
-    {
-        return;
-    }
-
-    char* name = hashTable.getString("Name");
-
-    JsonArray skills = hashTable.getArray("Skills");
-
-    int age = hashTable.getLong("Age");
-
-    bool online = hashTable.getBool("Online");
-
-
-
-How to  use ?
--------------
-
-### 1. Install the library
-
-Download the library and extract it to:
-
-    <your Arduino Sketch folder>/libraries/ArduinoJsonParser
-
-### 2. Import in your sketch
-
-Just add the following line on the top of your `.ino` file:
-
-    #include <JsonParser.h>
-    
-### 3. Create a parser
-
-To extract data from the JSON string, you need to create a `JsonParser`, and specify the number of token you allocate for the parser itself:
-
-    JsonParser<32> parser;
-    
-> #### How to choose the number of tokens ?
-
-> A token is an element of the JSON object: either a key, a value, an hash-table or an array.
-> As an example the `char json[]` on the top of this page contains 12 tokens (don't forget to count 1 for the whole object and 1 more for the array itself).
-
-> The more tokens you allocate, the more complex the JSON can be, but also the more memory is occupied.
-> Each token takes 8 bytes, so `sizeof(JsonParser<32>)` is 256 bytes which is quite big in an Arduino with only 2KB of RAM.
-> Don't forget that you also have to store the JSON string in RAM and it's probably big.
-
-> 32 tokens may seem small, but it's very decent for an 8-bit processor, you wouldn't get better results with other JSON libraries.
-
-### 4. Extract data
-
-To use this library, you need to know beforehand what is the type of data contained in the JSON string, which is very likely.
-
-The root object has to be either a hash-table (like `{"key":"value"}`) or an array (like `[1,2]`). 
-
-The nested objects can be either arrays, booleans, hash-tables, numbers or strings.
-If you need other type, you can get the string value and parse it yourself.
-
-#### Hash-table
-
-Consider we have a `char json[]` containing to the following JSON string:
-
-    {
-        "Name":"Blanchon",
-        "Skills":[
-            "C",
-            "C++",
-            "C#"],
-        "Age":32,
-        "Online":true
-    }
-
-In this case the root object of the JSON string is a hash-table, so you need to extract a `JsonHashTable`:
+#### Decoding / Parsing
    
-    JsonHashTable root = parser.parseHashTable(json);
-    
-To check if the parsing was successful, you must check:
+    char json[] = "{\"sensor\":\"gps\",\"time\":1351824120,\"data\":[48.756080,2.302038]}";
 
-    if (!root.success())
-    {
-        // Parsing fail: could be an invalid JSON, or too many tokens
-    }
-    
-And then extract the member you need:
-    
-    char* name = hashTable.getString("Name");
+    StaticJsonBuffer<200> jsonBuffer;
 
-    JsonArray skills = hashTable.getArray("Skills");
+    JsonObject& root = jsonBuffer.parseObject(json);
 
-    int age = hashTable.getLong("Age");
+    const char* sensor = root["sensor"];
+    long time          = root["time"];
+    double latitude    = root["data"][0];
+    double longitude   = root["data"][1];
 
-    bool online = hashTable.getBool("Online");
-    
-#### Array
+[See complete guide](/doc/Decoding JSON.md)
 
-Consider we have a `char json[]` containing to the following JSON string:
-
-    [
-        [ 1.2, 3.4 ],
-        [ 5.6, 7.8 ]               
-    ]
-
-In this case the root object of the JSON string is an array, so you need to extract a `JsonArray`:
+#### Encoding / Generating
    
-    JsonArray root = parser.parseArray(json);
-    
-To check if the parsing was successful, you must check:
+    StaticJsonBuffer<200> jsonBuffer;
 
-    if (!root.success())
-    {
-        // Parsing fail: could be an invalid JSON, or too many tokens
-    }
-    
-And then extract the content by its index in the array:
-    
-    JsonArray row0 = root.getArray(0);
-    double a = row0.getDouble(0);
-    
-or simply:
+    JsonObject& root = jsonBuffer.createObject();
+    root["sensor"] = "gps";
+    root["time"] = 1351824120;

-Common pitfalls
----------------
+[See complete guide](/doc/Encoding JSON.md)
 
-### 1. Not enough tokens
-
-By design, the library has no way to tell you why `JsonParser::parseArray()` or `JsonParser::parseHashTable()` failed.
-
-There are basically two reasons why they may fail:
-
-1. the JSON string is invalid
-2. the JSON string contains more tokens that the parser can store
-
-So, if you are sure the JSON string is correct and you still can't parse it, you should slightly increase the number of token of the parser.
-
-### 2. Not enough memory
-
-You may go into unpredictable trouble if you allocate more memory than your processor really has.
-It's a very common issue in embedded development. 
-
-To diagnose this, look at every big objects in you code and sum their size to check that they fit in RAM.
-
-For example, don't do this:
-
-    char json[1024];        // 1 KB
-    JsonParser<64> parser;    // 512 B
-
-because it may be too big for a processor with only 2 KB: you need free memory to store other variables and the call stack.
-
-That is why an 8-bit processor is not able to parse long and complex JSON strings.
-
-### 3. JsonParser not in memory
-
-To reduce the memory consumption, `JsonArray` and `JsonHashTable` contains pointer to the token that are inside the `JsonParser`. This can only work if the `JsonParser` is still in memory.
-
-For example, don't do this:
-
-    JsonArray getArray(char* json)
-    {
-        JsonParser<16> parser;
-        return parser.parseArray(parser); 
-    }
-
-because the local variable `parser` will be *removed* from memory when the function `getArray()` returns, and the pointer inside `JsonArray` will point to an invalid location.
-
-### 4. JSON string is altered
-
-This will probably never be an issue, but you need to be aware of this feature.
-
-When you pass a `char[]` to `JsonParser::parseArray()` or `JsonParser::parseHashTable()`, the content of the string will be altered to add `\0` at the end of the tokens.
-
-This is because we want functions like `JsonArray::getString()` to return a null-terminating string without any memory allocation.

+Avoiding common pitfalls in Arduino JSON
+========================================
+
+As `StaticJsonBuffer` is the corner stone of this library, you'll see that every pitfall listed here are related to a wrong understanding of the memory model.
+
+Make sure you read [Arduino JSON memory model](Memory model.md) before going further.
+
+## 1. Make `StaticJsonBuffer` big enough
+
+By design, the library has no way to tell you why `parseArray()` or `parseObject()` failed.
+
+There are basically two reasons why they may fail:
+
+1. the JSON string is invalid,
+2. the JSON string contains more values that the buffer can store.
+
+So, if you are sure the JSON string is correct and you still can't parse it, you should try to increase the size of the `StaticJsonBuffer`.
+
+## 2. Make sure everything fits in memory
+
+You may go into unpredictable trouble if you allocate more memory than your processor really has.
+It's a very common issue in embedded development.
+
+To diagnose this, look at every big objects in you code and sum their size to check that they fit in RAM.
+
+For example, don't do this:
+
+    char json[1024];                // 1 KB
+    StaticJsonBuffer<512> buffer;   // 514 B
+
+because it may be too big for a processor with only 2 KB: you need free memory to store other variables and the call stack.
+
+That is why an 8-bit processor is not able to parse long and complex JSON strings.
+
+## 3. Keep the `StaticJsonBuffer` in memory long enough
+
+Remember that `StaticJsonBuffer`'s function return references.
+References don't contain data, they are just pointer to the actual.
+So they can only work if the actual data is in memory.
+
+For example, don't do this:
+
+    JsonArray& getArray(char* json)
+    {
+        StaticJsonBuffer<200> buffer;
+        return buffer.parseArray(json); 
+    }
+
+because the local variable `buffer` will be *removed* from memory when the function `parseArray()` returns, and the `JsonArray&` will point to an invalid location.
+
+## 4. Don't reuse the same `StaticJsonBuffer`
+
+During is lifetime a `StaticJsonBuffer` growth until it's discarded. If you try to reuse the same instance several time, it will rapidly get full.
+
+For this reason, you should not use a global variable for your `StaticJsonBuffer`. I don't think there is any scenario in which a global `StaticJsonBuffer` would be a valid option.
+
+The best practice is to declare it in a local scope, so that it's discarded as soon as possible. My advice it to declare it in a function which unique role is to handle the JSON serialization.
+
+## 5. Keep the JSON string in memory long enough
+
+The library never make memory duplication.
+This has an important implication on string values, it means that the library will return pointer to chunks of the string.
+
+For instance, let's imagine that you parse `["hello","world"]`, like this:
+
+    char[] json = "[\"hello\",\"world\"]";
+    StaticJsonBuffer<32> buffer;
+    JsonArray& array = buffer.parseArray(json);
+
+    const char* first = array[0];
+    const char* second = array[1];
+
+In that case, both `first` and `second` are pointers to the content of the original string `json`.
+So this will only work if `json` is still in memory.
+
+## 6. JSON string is altered
+
+If you read carefully the previous section, you may have come to the conclusion that the JSON parser modifies the JSON string.
+
+Indeed, the parser modifies the string for two reasons:
+
+1. it inserts `\0` to terminate substrings,
+2. it translate escaped characters like `\n` or `\t`.
+
+Most of the time this wont be an issue, but there are some corner cases that can be problematic.
+
+Let take the example bellow:
+
+    char[] json = "[\"hello\",\"world\"]";
+    StaticJsonBuffer<32> buffer;
+    JsonArray& array = buffer.parseArray(json);
+
+If you replace it by:
+
+    char* json = "[\"hello\",\"world\"]";
+    StaticJsonBuffer<32> buffer;
+    JsonArray& array = buffer.parseArray(json);
+
+Depending on your platform, you may have an exception because the parser tries to write at a location that is read-only.
+In the first case `char json[]` declares an array of `char` initialized to the specified string.
+In the second case `char* json` declares a pointer to a read-only string, in fact it should be a `const char*` instead of a `char*`.

+Decoding JSON with Arduino JSON
+===============================
+
+Before writing any code, don't forget to include the header:
+
+    #include <ArduinoJson.h>
+
+For instructions on how to install the library, please read [Using the library with Arduino](Using the library with Arduino.md) or [Using the library without Arduino](Using the library without Arduino.md).
+
+## Example
+
+Here an example that parse the string `{"sensor":"gps","time":1351824120,"data":[48.756080,2.302038]}`:
+
+    char json[] = "{\"sensor\":\"gps\",\"time\":1351824120,\"data\":[48.756080,2.302038]}";
+    
+    //
+    // Step 1: Reserve memory space
+    //
+    StaticJsonBuffer<200> jsonBuffer;
+    
+    //
+    // Step 2: Deserialize the JSON string
+    //
+    JsonObject& root = jsonBuffer.parseObject(json);
+
+    if (!root.success())
+    {
+      Serial.println("parseObject() failed");
+      return;
+    }
+
+    //
+    // Step 3: Retrieve the values
+    //
+    const char* sensor    = root["sensor"];
+    long        time      = root["time"];
+    double      latitude  = root["data"][0];
+    double      longitude = root["data"][1];
+
+## Step 1: Reserve memory space
+
+Arduino JSON uses a preallocated memory pool to store the object tree, this is done by the `StaticJsonBuffer`.
+
+Before continuing please read the page [Arduino JSON memory model](Memory model.md) that explains everything you need to know about `StaticJsonBuffer`.
+
+## Step 2: Parse the JSON string
+
+You invoke the JSON parser through the instance of `StaticJsonBuffer`.
+It exposes two functions for parsing JSON:
+
+1. `parseArray()` that returns a reference to a `JsonArray`
+2. `parseObject()` that returns a reference to a `JsonObject`
+
+Let's see an example.
+Say we want to parse `{"sensor":"gps","time":1351824120,"data":[48.756080,2.302038]}`, it's an object so we call `parseObject()` as follows:
+
+    char json[] = "{\"sensor\":\"gps\",\"time\":1351824120,\"data\":[48.756080,2.302038]}";
+
+    JsonObject& root = jsonBuffer.parseObject(json);
+
+As you can see `parseObject()` takes a `char*` as a parameter.
+Be careful, it's not a `const char*`, the memory must be writable.
+Indeed, the parser will modify the string in two cases:
+
+1. to insert string endings (character `\0`),
+2. to translate escaped characters (like `\n` or `\t`).
+
+Another thing that you must keep in mind is that the string (`char json[]` in the example above) must stay in memory during the whole parsing process.
+That is because the in memory object tree will store pointer to chunks of the string, so as to avoid any memory duplication. 
+
+Now, to check if the parsing was successful, you can call `JsonObject::success()`:
+
+    if (!root.success())
+    {
+        // Parsing fail
+    }
+
+The result can be `false` for tree reasons:
+
+1. the JSON string is invalid,
+2. the JSON string doesn't represent an object,
+3. the `StaticJsonBuffer` is too small.
+
+We just saw how to parse an object, there is nothing more to say for arrays, the procedure is exactly the same.
+
+## Step 3: Retrieve the values
+
+Now that the object or array is in memory, you can extract the data very easily.
+
+In this section, we'll see how to do it with a `JsonObject`.
+Once again, there is nothing more to say about arrays, `JsonArray` works exactly the same as `JsonObject`.
+
+#### Subscript operator
+
+The simplest way is to use the subscript operator of `JsonObject`:
+    
+    const char* sensor = root["sensor"];
+    long time = root["time"];
+
+You can chain the subscript operator if you have nested arrays or objects:
+
+    double latitude  = root["data"][0];
+    double longitude = root["data"][1];
+
+But alternatively, you can get a reference to the nested array:
+
+    JsonArray& nestedArray = root["data"];
+
+#### Casting values
+
+In the previous examples, the values were implicitly casted to the target type.
+You can also do this explicitly
+
+    const char* sensor = root["sensor"].asString();
+    long time = root["time"].as<long>();
+    JsonArray& nestedArray = root["data"].asArray();
+
+If the actual value doesn't match the target type, a default value will be return:
+
+1. `false` for boolean values
+2. `0` for integer values
+3. `NULL` for string values
+4. `JsonArray::invalid()` for nested arrays
+5. `JsonObject::invalid()` for nested object
+
+#### Check values
+
+If you want to know if some value is present, call `containsKey()`:
+
+    if (root.contains("extra"))
+    {
+        // root["extra"] is valid
+    }
+
+If you want to check the type value has a certain type, call `is<T>()`:
+
+    if (root["extra"].is<JsonArray&>())
+    {
+        // root["extra"] is an array
+    }
+
+You can also iterate through the key-value pairs of the object:
+
+    for (JsonObject::itertor it=root.begin(); it!=root.end(); ++it)
+    {
+      Serial.println(it->key);
+      Serial.println(i->value.asString());
+    }

+
+For instructions on how to install the library, please read [Using the library with Arduino](Using the library with Arduino.md) or [Using the library without Arduino](Using the library without Arduino.md).
+
+## Example
+
+Here is an example to generate `{"sensor":"gps","time":1351824120,"data":[48.756080,2.302038]}`
+
+    //
+    // Step 1: Reserve memory space

+## Step 1: Reserve memory space
+
+Arduino JSON uses a preallocated memory pool to store the object tree, this is done by the `StaticJsonBuffer`.
+
+Before continuing please read the page [Arduino JSON memory model](Memory model.md) that explains everything you need to know about `StaticJsonBuffer`.
+
+## Step 2: Build object tree in memory
+
+Now that you have enough memory hold by the `StaticJsonBuffer`, you can use it to build your in-memory representation of the JSON string.
+
+#### Arrays
+
+You create an array like this:
+
+    JsonArray& array = jsonBuffer.createArray();
+
+Don't forget the `&` after `JsonArray`, it needs to be a reference to the array.
+
+Then you can add strings, integer, booleans, etc:
+
+    array.add("bazinga!");
+    array.add(42);
+    array.add(true);
+
+There are two syntaxes for floating point values:
+
+	array.add(3.1415, 4);  // 4 digits: "3.1415"
+    array.add(3.1415);	   // 2 digits: "3.14"
+
+> ##### About floating point precision
+> The overload of `add()` with 2 parameters allows you to specify the number of decimals to save in the JSON string.
+> When you use the overload with one parameter, you use the default number of decimals which is 2.
+> Note that this behavior is the exact same as Arduino's `Print::print(double,int);` which is implemented by `Serial`, so you may already be familiar with this behavior.
+
+You can add a nested array or object if you have a reference to it.
+Or simpler, you can create nested array or nested objects from the array:
+
+    JsonArray&  nestedArray  = array.createNestedArray();
+    JsonObject& nestedObject = array.createNestedObject();
+
+#### Objects
+
+You create an object like this:
+
+    JsonObject& object = jsonBuffer.createObject();
+
+Again, don't forget the `&` after `JsonObject`, it needs to be a reference to the object.
+
+Then you can add strings, integer, booleans, etc:
+
+    object["key1"] = "bazinga!";
+    object["key2"] = 42;
+    object["key3"] = true;
+
+As for the arrays, there are two syntaxes for the floating point values:
+
+	object["key4"].set(3.1415, 4);  // 4 digits "3.1415"
+    object["key5"] = 3.1415;	    // default: 2 digits "3.14"
+
+You can add a nested array or object if you have a reference to it.
+Or simpler, you can create nested array or nested objects from the object:
+
+    JsonArray&  nestedArray  = object.createNestedArray("key6");
+    JsonObject& nestedObject = object.createNestedObject("key7");
+
+> ##### Other JsonObject functions
+> * `object.add(key, value)` is a synonym for `object[key] = value`
+> * `object.containsKey(key)` returns `true` is the `key` is present in `object`
+> * `object.remove(key)` removes the `value` associated with `key`
+
+## Step 3: Generate the JSON string
+
+There are two ways tho get the resulting JSON string.
+
+Depending on your project, you may need to dump the string in a classic `char[]` or send it to a `Print` implementation like `Serial` or `EthernetClient `.
+
+Both ways are the easy way :-)
+
+#### Use a classic `char[]`
+
+Whether you have a `JsonArray&` or a `JsonObject&`, simply call `printTo()` with the destination buffer, like so:
+
+	char buffer[256];
+    array.printTo(buffer, sizeof(buffer));
+
+> ##### Want an indented output?
+> By default the generated JSON is as small as possible. It contains no extra space, nor line break.
+> But if you want an indented, more readable output, you can.
+> Simply call `prettyPrintTo` instead of `printTo()`:
+> 
+>     array.prettyPrintTo(buffer, sizeof(buffer));
+
+#### Send to a `Print` implementation
+
+It's very likely that the generated JSON will end up in a stream like `Serial` or `EthernetClient `, so you can save some time and memory by doing this:
+
+    array.printTo(Serial);
+
+And, of course if you need an indented JSON string:
+
+    array.prettyPrintTo(Serial);
+
+> ##### About the Print interface
+> The library is designed to send the JSON string to an implementation of the `Print` interface that is part of Arduino.
+> In the example above we used `Serial`, but they are many other implementations that would work as well, including: `HardwareSerial`,  `SoftwareSerial`, `LiquidCrystal`, `EthernetClient`, `WiFiClient`, `Wire`...
+> When you use this library out of the Arduino environment, it will use it's own implementation of `Print` and everything will be the same.

+Arduino JSON memory model
+=========================
+
+## Fixed memory allocation
+
+### Introducing `StaticJsonBuffer`
+
+Arduino JSON uses a preallocated memory pool to store the object tree, this is done by the `StaticJsonBuffer` class.
+
+Before using any function of the library you need to create a `StaticJsonBuffer`. Then you can use this instance to create arrays and objects, or parse a JSON string.
+
+`StaticJsonBuffer` has a template parameter that determines its capacity. For example, the following line create a `StaticJsonBuffer` with a capacity of 200 bytes:
+
+    StaticJsonBuffer<200> jsonBuffer;
+
+The bigger the buffer is, the more complex the object tree can be, but also the more memory you need.
+
+### How to determine the buffer size?
+
+So the big question you should have in mind right now is *How can I determine the size?*.
+
+There are basically two approaches here:
+
+1. either you can predict the content of the object tree,
+2. or, you know how much memory is available.
+
+In the first case, you know some constraints on the object tree. For instance, let's say that your know in advance (and by that I mean "at compilation time") that you want to generate an object with 3 values, one of them being an array with 2 values, like the following:
+
+    {"sensor":"gps","time":1351824120,"data":[48.756080,2.302038]}
+
+To determine the memory usage of this object tree, you use the two macros `JSON_ARRAY_SIZE(n)` and `JSON_OBJECT_SIZE(n)`, both take the number of elements as an argument.
+For the example above, it would be:
+
+    const int BUFFER_SIZE = JSON_OBJECT_SIZE(3) + JSON_ARRAY_SIZE(2);
+    StaticJsonBuffer<BUFFER_SIZE> jsonBuffer;
+
+In the second case, let's say you dynamically generate a JSON object tree of a random complexity so you can't put a limit based on that. But on the other hand, you don't want your program to crash because the object tree doesn't fit in memory.
+The solution here is to determine how much memory is available, or in other words how much memory you can afford for the JSON object tree.
+
+### Why choosing fixed allocation?
+
+This fixed allocation approach may seem a bit strange, especially if your a desktop application developer used to dynamic allocation, but it make a lot of sense in an embedded context:
+
+1. the code is smaller
+2. it uses less memory
+3. it doesn't create memory fragmentation
+4. it predictable
+
+Don't forget that the memory is "freed" as soon as the `StaticJsonBuffer` is out of scope, like any other variable. It only hold the memory for a short amount of time.
+
+## Memory usage
+
+#### Object size for 8-bit AVR
+
+| Type                    | Size       |
+|-------------------------|------------|
+| JsonArray of N element  | 4 + 8 * N  |
+| JsonObject of N element | 4 + 10 * N |

+Migrating code written for Arduino JSON v3 to v4
+================================================
+
+Arduino JSON v4 was a major rewrite of the library, and the API changed significantly.
+
+## Includes
+
+Arduino JSON v3 had two include files:
+
+    #include <JsonParser.h>
+    #include <JsonGenerator.h>
+
+Arduino JSON v4 only has one:
+
+	#include <ArduinoJson.h>
+
+## Namespaces
+
+Arduino JSON v3 had two namespaces:
+
+	using namespace ArduinoJson::Parser;
+	using namespace ArduinoJson::Generator;
+
+Arduino JSON v4 doesn't require the `using namespace` statement.
+It has a namespace but the `using namespace` is done in the header file.
+
+## StaticJsonBuffer
+
+Arduino JSON v3 had different memory allocation models for the parser:
+
+	JsonParser<16> parser; // 16 being the capacity in "tokens"
+
+and for the generator:
+
+	JsonArray<4> array; // 4 being the number of element
+	JsonObject<4> object;
+
+Arduino JSON v4 only has one memory allocation model:
+
+	StaticJsonBuffer<128> buffer; // 128 being the capacity in bytes
+
+## Return values for the parser
+
+Arduino JSON v3 returned value types:
+
+	JsonArray array = parser.parseArray(json);
+	JsonObject object = parser.parseObject(json);
+
+Arduino JSON v4 returns references types:
+
+	JsonArray& array = buffer.parseArray(json);
+	JsonObject& object = buffer.parseObject(json);
+
+Everything else is compatible
+
+## Creating arrays and objects
+
+Arduino JSON v3 allowed to create `JsonArray` and `JsonObject` directly:
+
+	JsonArray<4> array;
+	JsonObject<4> object;
+
+Arduino JSON v4 requires that you use a `StaticJsonBuffer` for that:
+
+	JsonArray& array = buffer.createArray();
+	JsonObject& object = buffer.createObject();
+
+Note: you don't have to specify the capacity anymore.
+
+## Printable interface
+
+Arduino JSON v3 used to implement the Printable interface, which allowed statements like:
+
+    Serial.print(array);
+
+But Arduino JSON v4 doesn't, instead you need to write this:
+
+	array.printTo(Serial);
+
+Note: there was a good reason for removing that feature, and it's reducing the size of `JsonArray` and `JsonObject`.
