 Simplifications
 ---------------
 
 After having unit tests for the parser function in place, I started refactoring the parser functions (as well as others) and making them easier to read and maintain.

-- Use goto-fail in several parser functions (#100)
-- Rewrite/restructure all of the parsing functions to be easier to understand and have less code paths doing the same as another. (#109)
-- Simplify the buffer allocation strategy to always doubling the needed amount (9f6fa94c91a87b71e4c6868dbf2ce431a48517b0)

 There are several ways to incorporate cJSON into your project.
 
 #### copying the source
+
 Because the entire library is only one C file and one header file, you can just copy `cJSON.h` and `cJSON.c` to your projects source and start using it.
 
 cJSON is written in ANSI C (C89) in order to support as many platforms and compilers as possible.
 
 #### CMake
+
 With CMake, cJSON supports a full blown build system. This way you get the most features. CMake with an equal or higher version than 2.8.5 is supported. With CMake it is recommended to do an out of tree build, meaning the compiled files are put in a directory separate from the source files. So in order to build cJSON with CMake on a Unix platform, make a `build` directory and run CMake inside it.

 And install it with `make install` if you want. By default it installs the headers `/usr/local/include/cjson` and the libraries to `/usr/local/lib`. It also installs files for pkg-config to make it easier to detect and use an existing installation of CMake. And it installs CMake config files, that can be used by other CMake based projects to discover the library.
 
 You can change the build process with a list of different options that you can pass to CMake. Turn them on with `On` and off with `Off`:
+
 * `-DENABLE_CJSON_TEST=On`: Enable building the tests. (on by default)
 * `-DENABLE_CJSON_UTILS=On`: Enable building cJSON_Utils. (off by default)
 * `-DENABLE_TARGET_EXPORT=On`: Enable the export of CMake targets. Turn off if it makes problems. (on by default)

 On Windows CMake is usually used to create a Visual Studio solution file by running it inside the Developer Command Prompt for Visual Studio, for exact steps follow the official documentation from CMake and Microsoft and use the online search engine of your choice. The descriptions of the the options above still generally apply, although not all of them work on Windows.
 
 #### Makefile
+
+**NOTE:** This Method is deprecated. Use CMake if at all possible. Makefile support is limited to fixing bugs.

 If you don't have CMake available, but still have GNU make. You can use the makefile to build cJSON:

+cd vcpkg
+./bootstrap-vcpkg.sh
+./vcpkg integrate install
+vcpkg install cjson
+```
+
+The cJSON port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please [create an issue or pull request](https://github.com/Microsoft/vcpkg) on the vcpkg repository.
 
 ### Including cJSON
+
 If you installed it via CMake or the Makefile, you can include cJSON like this:
 
 ```c
@@ -169,39 +190,43 @@ An item of this type represents a JSON value. The type is stored in `type` as a
 To check the type of an item, use the corresponding `cJSON_Is...` function. It does a `NULL` check followed by a type check and returns a boolean value if the item is of this type.
 
 The type can be one of the following:
+
 * `cJSON_Invalid` (check with `cJSON_IsInvalid`): Represents an invalid item that doesn't contain any value. You automatically have this type if you set the item to all zero bytes.
 * `cJSON_False` (check with `cJSON_IsFalse`): Represents a `false` boolean value. You can also check for boolean values in general with `cJSON_IsBool`.
 * `cJSON_True` (check with `cJSON_IsTrue`): Represents a `true` boolean value. You can also check for boolean values in general with `cJSON_IsBool`.
 * `cJSON_NULL` (check with `cJSON_IsNull`): Represents a `null` value.
 * `cJSON_Number` (check with `cJSON_IsNumber`): Represents a number value. The value is stored as a double in `valuedouble` and also in `valueint`. If the number is outside of the range of an integer, `INT_MAX` or `INT_MIN` are used for `valueint`.
 * `cJSON_String` (check with `cJSON_IsString`): Represents a string value. It is stored in the form of a zero terminated string in `valuestring`.
-* `cJSON_Array` (check with `cJSON_IsArray`): Represent an array value. This is implemented by pointing `child` to a linked list of `cJSON` items that represent the values in the array. The elements are linked together using `next` and `prev`, where the first element has `prev == NULL` and the last element `next == NULL`.
+* `cJSON_Array` (check with `cJSON_IsArray`): Represent an array value. This is implemented by pointing `child` to a linked list of `cJSON` items that represent the values in the array. The elements are linked together using `next` and `prev`, where the first element has `prev.next == NULL` and the last element `next == NULL`.
 * `cJSON_Object` (check with `cJSON_IsObject`): Represents an object value. Objects are stored same way as an array, the only difference is that the items in the object store their keys in `string`.
 * `cJSON_Raw` (check with `cJSON_IsRaw`): Represents any kind of JSON that is stored as a zero terminated array of characters in `valuestring`. This can be used, for example, to avoid printing the same static JSON over and over again to save performance. cJSON will never create this type when parsing. Also note that cJSON doesn't check if it is valid JSON.
 
 Additionally there are the following two flags:
-* `cJSON_IsReference`: Specifies that the item that `child` points to and/or `valuestring` is not owned by this item, it is only a reference. So `cJSON_Delete` and other functions will only deallocate this item, not it's children/valuestring.

 * `cJSON_StringIsConst`: This means that `string` points to a constant string. This means that `cJSON_Delete` and other functions will not try to deallocate `string`.
 
 ### Working with the data structure
 
 For every value type there is a `cJSON_Create...` function that can be used to create an item of that type.
 All of these will allocate a `cJSON` struct that can later be deleted with `cJSON_Delete`.
-Note that you have to delete them at some point, otherwise you will get a memory leak.
-**Important**: If you have added an item to an array or an object already, you **mustn't** delete it with `cJSON_Delete`. Adding it to an array or object transfers its ownership so that when that array or object is deleted, it gets deleted as well.

 #### Basic types
+
 * **null** is created with `cJSON_CreateNull`
 * **booleans** are created with `cJSON_CreateTrue`, `cJSON_CreateFalse` or `cJSON_CreateBool`
 * **numbers** are created with `cJSON_CreateNumber`. This will set both `valuedouble` and `valueint`. If the number is outside of the range of an integer, `INT_MAX` or `INT_MIN` are used for `valueint`
-* **strings** are created with `cJSON_CreateString` (copies the string) or with `cJSON_CreateStringReference` (directly points to the string. This means that `valuestring` won't be deleted by `cJSON_Delete` and you are responsible for it's lifetime, useful for constants)

 #### Arrays
 
 You can create an empty array with `cJSON_CreateArray`. `cJSON_CreateArrayReference` can be used to create an array that doesn't "own" its content, so its content doesn't get deleted by `cJSON_Delete`.
 
 To add items to an array, use `cJSON_AddItemToArray` to append items to the end.
-Using `cJSON_AddItemReferenceToArray` an element can be added as a reference to another item, array or string. This means that `cJSON_Delete` will not delete that items `child` or `valuestring` properties, so no double frees are occuring if they are already used elsewhere.

 `return_parse_end` returns a pointer to the end of the JSON in the input string or the position that an error occurs at (thereby replacing `cJSON_GetErrorPtr` in a thread safe way). `require_null_terminated`, if set to `1` will make it an error if the input string contains data after the JSON.
