 Support for AVX-512 require a processor with AVX512-VBMI2 support (Ice Lake or better, AMD Zen 4 or better) under a 64-bit system and a recent compiler (LLVM clang 6 or better, GCC 8 or better, Visual Studio 2019 or better). You need a correspondingly recent assembler such as gas (2.30+) or nasm (2.14+): recent compilers usually come with recent assemblers. If you mix a recent compiler with an incompatible/old assembler (e.g., when using a recent compiler with an old Linux distribution), you may get errors at build time because the compiler produces instructions that the assembler does not recognize: you should update your assembler to match your compiler (e.g., upgrade binutils to version 2.30 or better under Linux) or use an older compiler matching the capabilities of your assembler.

 Note:
+- We recommend that you use simdjson by copying the single-header `simdjson.h` file along with the source file `simdjson.cpp` directly in your project, as they are part of [every release](https://github.com/simdjson/simdjson/releases) as assets. In this manner, you only have to compile `simdjson.cpp` as any other source file: it works well in every development environment. However, you may also use simdjson as a git submodule ([example](https://github.com/simdjson/cmakedemo)), using FetchContent ([example](https://github.com/simdjson/cmake_demo_single_file)), with ExternalProject_Add ([example](https://github.com/simdjson/cmakedemo_externalproject)) or with CPM ([example](https://github.com/cpm-cmake/CPM.cmake/tree/master/examples/simdjson)).
 - Users on macOS and other platforms where default compilers do not provide C++11 compliant by default should request it with the appropriate flag (e.g., `c++ -std=c++11 myproject.cpp simdjson.cpp`).

If you need several keys and you cannot predict the order they will appear in, it is recommended to iterate through all keys `for(auto field : object) {...}`.  Keep in mind that On Demand does not buffer or save the result of the parsing: if you repeatedly access `object["foo"]`, then it must repeatedly seek the key and parse the content. The library does not provide a distinct function to check if a key is present, instead we recommend you attempt to access the key: e.g., by doing `ondemand::value val{}; if (!object["foo"].get(val)) {...}`, you have that `val` contains the requested value inside the if clause.

 - To better understand the operation of your On Demand parser, and whether it is performing as well as you think it should be, there is a  logger feature built in to simdjson! To use it, define the pre-processor directive `SIMDJSON_VERBOSE_LOGGING` prior to including the `simdjson.h` header, which enables logging in simdjson. Run your code. It may generate a lot of logging output; adding printouts from your application that show each section may be helpful. The log's output will show step-by-step information on state, buffer pointer position, depth, and key retrieval status. Importantly, unless `SIMDJSON_VERBOSE_LOGGING` is defined, logging is entirely disabled and thus carries no overhead.

 the macro `SIMDJSON_AVX512_ALLOWED` to `0` in C++ prior to importing the headers.

 You may still be worried about which SIMD instruction set is used by simdjson.  Thankfully,  [you can always determine and change which architecture-specific implementation is used](implementation-selection.md) by simdjson. Thus even if your CPU supports AVX2, you do not need to use AVX2. You are in control.
+
+
+Free Padding
+-------
+
+For performance reasons, the simdjson library requires that the JSON input contain at least
+`simdjson::SIMDJSON_PADDING` bytes at the end of the stream. The value `simdjson::SIMDJSON_PADDING` is
+small (e.g., 64 bytes). On modern systems, you can safely read beyond an allocated buffers,
+as long as you remain within an allocated page. Pages on modern systems span at least 4 kilobytes,
+but can be significantly larger. E.g., Apple systems favour pages spanning 16 kilobytes.
+
+In effect, it means that you can almost always read a few bytes beyond your current buffer---without
+allocating extra memory. However, tools such as valgrind or memory sanitizers will flag such behavior as unsafe.
+Nevertheless, you can still make sure of this capability in your code if you are an expert
+programmer and you are willing to silence sanitizer warnings. The following code provides
+a portable example.
+
+
+The conditional compilation checks for the `_MSC_VER` macro (indicating Microsoft Visual Studio)
+and includes platform-specific headers accordingly.
+The `page_size()` function determines the default size of a memory page in bytes on the system.
+On Windows (when `_WIN32` is defined), it uses `GetSystemInfo()` to retrieve system information and obtain the page size.
+On other platforms (non-Windows), it uses `sysconf(_SC_PAGESIZE)` to get the page size.
+The function returns the page size.
+The `need_allocation()` function checks whether the buffer (given by `buf`) plus the specified length (`len`) is near a page boundary.
+If the buffer extends beyond the current page when padded by `simdjson::SIMDJSON_PADDING`, it returns true, indicating that reallocation is needed.
+Otherwise, it returns false.
+The `get_padded_string_view()`  creates a `padded_string_view` from the input buffer.
+If reallocation is needed (unlikely case), it allocates a new padded_string and assigns it to `jsonbuffer`.
+Otherwise (very likely), it creates a `padded_string_view` directly from the buffer.
+The `simdjson::SIMDJSON_PADDING` ensures that there is additional padding for parsing efficiency.
+The calling code just needs to provide `jsonbuffer` (an instance of `simdjson::padded_string`)
+and pass `get_padded_string_view(buf, len, jsonbuffer)` to  `parser.iterate`. Most of the time,
+this code will not allocate new memory.
