+
+## Building
+
+Both CMake and Meson tools are capable of generating a variety of build environments for you preferred development environment.
+Using cmake or meson you can generate an XCode, Visual Studio, Unix Makefile, Ninja, or other environment that fits your needs.
+
+An example of a common Meson/Ninja environment is described next.
+
+## Building and testing with Meson/Ninja
+Thanks to David Seifert (@SoapGentoo), we (the maintainers) now use
+[meson](http://mesonbuild.com/) and [ninja](https://ninja-build.org/) to build
+for debugging, as well as for continuous integration (see
+[`./.travis_scripts/meson_builder.sh`](./.travis_scripts/meson_builder.sh) ). Other systems may work, but minor
+things like version strings might break.
+
+First, install both meson (which requires Python3) and ninja.
+If you wish to install to a directory other than /usr/local, set an environment variable called DESTDIR with the desired path:
+    DESTDIR=/path/to/install/dir
+
+Then,
+```sh
+    cd jsoncpp/
+    BUILD_TYPE=debug
+    #BUILD_TYPE=release
+    LIB_TYPE=shared
+    #LIB_TYPE=static
+    meson --buildtype ${BUILD_TYPE} --default-library ${LIB_TYPE} . build-${LIB_TYPE}
+    ninja -v -C build-${LIB_TYPE}
+
+    ninja -C build-static/ test
+
+    # Or
+    #cd build-${LIB_TYPE}
+    #meson test --no-rebuild --print-errorlogs
+
+    sudo ninja install
+```
+
+## Building and testing with other build systems
+See https://github.com/open-source-parsers/jsoncpp/wiki/Building
+
+## Running the tests manually
+
+You need to run tests manually only if you are troubleshooting an issue.
+
+In the instructions below, replace `path/to/jsontest` with the path of the
+`jsontest` executable that was compiled on your platform.
+
+    cd test
+    # This will run the Reader/Writer tests
+    python runjsontests.py path/to/jsontest
+
+    # This will run the Reader/Writer tests, using JSONChecker test suite
+    # (http://www.json.org/JSON_checker/).
+    # Notes: not all tests pass: JsonCpp is too lenient (for example,
+    # it allows an integer to start with '0'). The goal is to improve
+    # strict mode parsing to get all tests to pass.
+    python runjsontests.py --with-json-checker path/to/jsontest
+
+    # This will run the unit tests (mostly Value)
+    python rununittests.py path/to/test_lib_json
+
+    # You can run the tests using valgrind:
+    python rununittests.py --valgrind path/to/test_lib_json
+
+## Building the documentation
+
+Run the Python script `doxybuild.py` from the top directory:
+
+    python doxybuild.py --doxygen=$(which doxygen) --open --with-dot
+
+See `doxybuild.py --help` for options.
+
+## Adding a reader/writer test
+
+To add a test, you need to create two files in test/data:
+
+* a `TESTNAME.json` file, that contains the input document in JSON format.
+* a `TESTNAME.expected` file, that contains a flatened representation of the
+  input document.
+
+The `TESTNAME.expected` file format is as follows:
+
+* Each line represents a JSON element of the element tree represented by the
+  input document.
+* Each line has two parts: the path to access the element separated from the
+  element value by `=`. Array and object values are always empty (i.e.
+  represented by either `[]` or `{}`).
+* Element path `.` represents the root element, and is used to separate object
+  members. `[N]` is used to specify the value of an array element at index `N`.
+
+See the examples `test_complex_01.json` and `test_complex_01.expected` to better understand element paths.
+
+## Understanding reader/writer test output
+
+When a test is run, output files are generated beside the input test files. Below is a short description of the content of each file:
+
+* `test_complex_01.json`: input JSON document.
+* `test_complex_01.expected`: flattened JSON element tree used to check if
+  parsing was corrected.
+* `test_complex_01.actual`: flattened JSON element tree produced by `jsontest`
+  from reading `test_complex_01.json`.
+* `test_complex_01.rewrite`: JSON document written by `jsontest` using the
+  `Json::Value` parsed from `test_complex_01.json` and serialized using
+  `Json::StyledWritter`.
+* `test_complex_01.actual-rewrite`: flattened JSON element tree produced by
+  `jsontest` from reading `test_complex_01.rewrite`.
+* `test_complex_01.process-output`: `jsontest` output, typically useful for
+  understanding parsing errors.
+
+## Versioning rules
+
+Consumers of this library require a strict approach to incrementing versioning of the JsonCpp library. Currently, we follow the below set of rules:
+
+* Any new public symbols require a minor version bump.
+* Any alteration or removal of public symbols requires a major version bump, including changing the size of a class. This is necessary for
+consumers to do dependency injection properly.
+
+## Preparing code for submission
+
+Generally, JsonCpp's style guide has been pretty relaxed, with the following common themes:
+
+* Variables and function names use lower camel case (E.g. parseValue or collectComments).
+* Class use camel case (e.g. OurReader)
+* Member variables have a trailing underscore
+* Prefer `nullptr` over `NULL`.
+* Passing by non-const reference is allowed.
+* Single statement if blocks may omit brackets.
+* Generally prefer less space over more space.
+
+For an example:
+
+```c++
+bool Reader::decodeNumber(Token& token) {
+  Value decoded;
+  if (!decodeNumber(token, decoded))
+    return false;
+  currentValue().swapPayload(decoded);
+  currentValue().setOffsetStart(token.start_ - begin_);
+  currentValue().setOffsetLimit(token.end_ - begin_);
+  return true;
+}
+```
+
+Before submitting your code, ensure that you meet the versioning requirements above, follow the style guide of the file you are modifying (or the above rules for new files), and run clang format. Meson exposes clang format with the following command:
+```
+ninja -v -C build-${LIB_TYPE}/ clang-format
+```
+
+For convenience, you can also run the `reformat.sh` script located in the root directory.

+[JSON][json-org] is a lightweight data-interchange format. It can represent
+numbers, strings, ordered sequences of values, and collections of name/value
+pairs.
+
+[json-org]: http://json.org/
+
+JsonCpp is a C++ library that allows manipulating JSON values, including
+serialization and deserialization to and from strings. It can also preserve
+existing comment in unserialization/serialization steps, making it a convenient
+format to store user input files.
+
+
+## Documentation
+
+[JsonCpp documentation][JsonCpp-documentation] is generated using [Doxygen][].
+
+[JsonCpp-documentation]: http://open-source-parsers.github.io/jsoncpp-docs/doxygen/index.html
+[Doxygen]: http://www.doxygen.org
+
+
+## A note on backward-compatibility
+
+* `1.y.z` is built with C++11.
+* `0.y.z` can be used with older compilers.
+* `00.11.z` can be used both in old and new compilers.
+* Major versions maintain binary-compatibility.
+
+### Special note
+The branch `00.11.z`is a new branch, its major version number `00` is to show that it is
+different from `0.y.z` and `1.y.z`, the main purpose of this branch is to make a balance
+between the other two branches. Thus, users can use some new features in this new branch
+that introduced in 1.y.z, but can hardly applied into 0.y.z.
+
+## Using JsonCpp in your project
+
+### The vcpkg dependency manager
+You can download and install JsonCpp using the [vcpkg](https://github.com/Microsoft/vcpkg/) dependency manager:

+
+The JsonCpp 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.
+
+### Amalgamated source
+https://github.com/open-source-parsers/jsoncpp/wiki/Amalgamated-(Possibly-outdated)
+
+### The Meson Build System
+If you are using the [Meson Build System](http://mesonbuild.com), then you can get a wrap file by downloading it from [Meson WrapDB](https://wrapdb.mesonbuild.com/jsoncpp), or simply use `meson wrap install jsoncpp`.

+/**
+\mainpage
+\section _intro Introduction
+
+<a HREF="http://www.json.org/">JSON (JavaScript Object Notation)</a>
+ is a lightweight data-interchange format.
+
+Here is an example of JSON data:
+\verbatim
+{
+    "encoding" : "UTF-8",
+    "plug-ins" : [
+        "python",
+        "c++",
+        "ruby"
+        ],
+    "indent" : { "length" : 3, "use_space": true }
+}
+\endverbatim
+<b>JsonCpp</b> supports comments as <i>meta-data</i>:
+\code
+// Configuration options
+{
+    // Default encoding for text
+    "encoding" : "UTF-8",
+
+    // Plug-ins loaded at start-up
+    "plug-ins" : [
+        "python",
+        "c++",  // trailing comment
+        "ruby"
+        ],
+
+    // Tab indent size
+    // (multi-line comment)
+    "indent" : { /*embedded comment*/ "length" : 3, "use_space": true }
+}
+\endcode
+
+\section _features Features
+- read and write JSON document
+- attach C++ style comments to element during parsing
+- rewrite JSON document preserving original comments
+
+Notes: Comments used to be supported in JSON but were removed for
+portability (C like comments are not supported in Python). Since
+comments are useful in configuration/input file, this feature was
+preserved.
+
+\section _example Code example
+
+\code
+Json::Value root;   // 'root' will contain the root value after parsing.
+std::cin >> root;
+
+// You can also read into a particular sub-value.
+std::cin >> root["subtree"];
+
+// Get the value of the member of root named 'encoding',
+// and return 'UTF-8' if there is no such member.
+std::string encoding = root.get("encoding", "UTF-8" ).asString();
+
+// Get the value of the member of root named 'plug-ins'; return a 'null' value if
+// there is no such member.
+const Json::Value plugins = root["plug-ins"];
+
+// Iterate over the sequence elements.
+for ( int index = 0; index < plugins.size(); ++index )
+   loadPlugIn( plugins[index].asString() );
+
+// Try other datatypes. Some are auto-convertible to others.
+foo::setIndentLength( root["indent"].get("length", 3).asInt() );
+foo::setIndentUseSpace( root["indent"].get("use_space", true).asBool() );
+
+// Since Json::Value has an implicit constructor for all value types, it is not
+// necessary to explicitly construct the Json::Value object.
+root["encoding"] = foo::getCurrentEncoding();
+root["indent"]["length"] = foo::getCurrentIndentLength();
+root["indent"]["use_space"] = foo::getCurrentIndentUseSpace();
+
+// If you like the defaults, you can insert directly into a stream.
+std::cout << root;
+// Of course, you can write to `std::ostringstream` if you prefer.
+
+// If desired, remember to add a linefeed and flush.
+std::cout << std::endl;
+\endcode
+
+\section _advanced Advanced usage
+
+Configure *builders* to create *readers* and *writers*. For
+configuration, we use our own `Json::Value` (rather than
+standard setters/getters) so that we can add
+features without losing binary-compatibility.
+
+\code
+// For convenience, use `writeString()` with a specialized builder.
+Json::StreamWriterBuilder wbuilder;
+wbuilder["indentation"] = "\t";
+std::string document = Json::writeString(wbuilder, root);
+
+// Here, using a specialized Builder, we discard comments and
+// record errors as we parse.
+Json::CharReaderBuilder rbuilder;
+rbuilder["collectComments"] = false;
+std::string errs;
+bool ok = Json::parseFromStream(rbuilder, std::cin, &root, &errs);
+\endcode
+
+Yes, compile-time configuration-checking would be helpful,
+but `Json::Value` lets you
+write and read the builder configuration, which is better! In other words,
+you can configure your JSON parser using JSON.
+
+CharReaders and StreamWriters are not thread-safe, but they are re-usable.
+\code
+Json::CharReaderBuilder rbuilder;
+cfg >> rbuilder.settings_;
+std::unique_ptr<Json::CharReader> const reader(rbuilder.newCharReader());
+reader->parse(start, stop, &value1, &errs);
+// ...
+reader->parse(start, stop, &value2, &errs);
+// etc.
+\endcode

+***NOTE***
+
+If you get linker errors about undefined references to symbols that involve types in the `std::__cxx11` namespace or the tag
+`[abi:cxx11]` then it probably indicates that you are trying to link together object files that were compiled with different
+values for the _GLIBCXX_USE_CXX11_ABI marco. This commonly happens when linking to a third-party library that was compiled with
+an older version of GCC. If the third-party library cannot be rebuilt with the new ABI, then you need to recompile your code with
+the old ABI,just like:
+**g++ stringWrite.cpp -ljsoncpp -std=c++11 -D_GLIBCXX_USE_CXX11_ABI=0 -o stringWrite**
+
+Not all of uses of the new ABI will cause changes in symbol names, for example a class with a `std::string` member variable will
+have the same mangled name whether compiled with the older or new ABI. In order to detect such problems, the new types and functions
+are annotated with the abi_tag attribute, allowing the compiler to warn about potential ABI incompatibilities in code using them.
+Those warnings can be enabled with the `-Wabi-tag` option.
