+## Introduction and Library Instances
+
+`StackCheckLib` contains the required functionality for initializing the stack cookie
+value, checking the value, and triggering an interrupt when a mismatch occurs.
+The stack cookie is a random value placed on the stack between the stack variables
+and the return address so that continuously writing past the stack variables will
+cause the stack cookie to be overwritten. Before the function returns, the stack
+cookie value will be checked and if there is a mismatch then `StackCheckLib` handles
+the failure.
+
+Because UEFI doesn't use the C runtime libraries provided by MSVC, the stack
+check code is written in assembly within this library. GCC and Clang compilers
+have built-in support for stack cookie checking, so this library only handles failures.
+
+### StackCheckLibStaticInit
+
+`StackCheckLibStaticInit` is an instance of `StackCheckLib` which does not update the
+stack cookie value for the module at runtime. It's always preferable to use
+`StackCheckLibDynamicInit` for improved security but there are cases where the stack
+cookie global cannot be written to such as in execute-in-place (XIP) modules and during
+the Cache-as-RAM (CAR) phase of the boot process. The stack cookie value is initialized
+at compile time via updates to the AutoGen process. Each module will define
+`STACK_COOKIE_VALUE` which is used for the module stack cookie value.
+
+### StackCheckLibDynamicInit
+
+This section is future work. The below is the proposed instance.
+
+`StackCheckLibDynamicInit` is an instance of `StackCheckLib` which updates the stack
+cookie value for the module at runtime. This is the preferred method for stack cookie
+initialization as it provides improved security. The stack cookie value is initialized
+at runtime by calling `GetRandomNumber32()` or `GetRandomNumber64()` to generate a random
+value via the platform's random number generator protocol. If the random number generator
+returns an error, then the value will still have the build-time randomized value to fall
+back on.
+
+### StackCheckLibNull
+
+`StackCheckLibNull` is an instance of `StackCheckLib` which does not perform any stack
+cookie checks. This is useful for modules which will fail if stack cookie checks are
+inserted. Of course, this is not recommended for production code.
+
+## How Failures are Handled
+
+When a stack cookie check fails, the `StackCheckLib` library will first call into a hook
+function `StackCheckFailureHook()` which only has a NULL implementation in edk2.
+The NULL implementation will simply print the failure address and return, but a platform
+can implement their own instance of this library which can perform additional actions
+before the system triggers an interrupt.
+
+After `StackCheckFailureHook()` returns, the library will trigger an interrupt with
+PcdStackCookieExceptionVector.
+
+- On IA32 and X64 platforms, PcdStackCookieExceptionVector is used as an index into the
+Interrupt Descriptor Table.
+- On ARM platforms, a software interrupt (`SWI`) is called with the value of
+PcdStackCookieExceptionVector. The value can be retrieved by the handler by reading
+bits [7:0] of the instruction opcode which will allow the handler to determine if the
+interrupt was triggered by the stack cookie check. Reference:
+[Arm A64 Instruction Set Architecture Version 2024-3](https://developer.arm.com/documentation/ddi0597/2024-03/Base-Instructions/SVC--Supervisor-Call-?lang=en)
+- On AARCH64 platforms, a supervisor call (`SVC`) is called with the value
+of PcdStackCookieExceptionVector. This value can similarly be retrieved by the
+handler to determine if the interrupt was triggered by the stack cookie check. Reference:
+[Arm A64 Instruction Set Architecture Version 2024-3](https://developer.arm.com/documentation/ddi0602/2024-03/Base-Instructions/SVC--Supervisor-Call-?lang=en)
+
+## Debugging Stack Cookie Check Failures
+
+Tracking down the origin of stack cookie failures can be difficult. Programmers may attempt
+printf debugging to determine which function has an overflow only to find that the failure
+disappears on the next boot. This curiosity is usually due to the black-box heuristic used
+by compilers to determine where to put stack cookie checks or compiler optimization features
+removing the failing check. The address where the failed stack cookie check occurred will
+be printed using DebugLib. If .map files are available, the address combined with the image
+offset can be used to determine the function which failed.
+
+GNU-based compilers have the `-fstack-protector-all` flag to force stack cookie checks on
+all functions which could create a more consistent environment for debugging assuming an
+earlier failure doesn't mask the targeted one and the flash space can accommodate the
+increased size.
+
+The Visual Studio (MSVC) toolchain has the ability to generate `.cod` files during compilation
+which interleave C and the generated assembly code. These files will contain the stack cookie
+checks and are useful for determining where the checks are placed. To generate these files,
+append `/FAcs` to the build options for each target module. The easiest way to do this is to
+update the tools_def file so the `<TARGET>_<TOOLCHAIN>_<ARCH>_CC_FLAGS` includes `/FAcs`.
+
+## Usage
+
+edk2 updated the tools_def to add `/GS` to VS2022 and VS2019 IA32/X64 builds and
+`-fstack-protector` to GCC builds. This will cause stack cookie references to be inserted
+throughout the code. Every module should have a `StackCheckLib` instances linked to satisfy
+these references. So every module doesn't need to add `StackCheckLib` to the LibraryClasses
+section of the INF file, `StackCheckLib` instances should be linked as NULL in the platform
+DSC fies. The only exception to this is host-based unit tests as they will be compiled with
+the runtime libraries which already contain the stack cookie definitions and will collide
+with `StackCheckLib`.
+
+SEC and PEI_CORE modules should always use `StackCheckLibNull` and pre-memory modules
+should use `StackCheckLibStaticInit`. All other modules should use `StackCheckLibDynamicInit`.
+Below is an **example** of how to link the `StackCheckLib` instances in the platform DSC file
+but it may need customization based on the platform's requirements:
