 ## Other Build Options
 
+##### Custom Task Management System
+
+USD uses task-based parallelism to improve scalability and performance. This foundation for this is located in the
+"work" library in pxr/base/work. By default, this library is implemented using the Intel TBB or oneAPI oneTBB
+library.
+
+Users may substitute their own task management system by providing a custom implementation for the work library.
+To do so, set the cmake variable `PXR_WORK_IMPL` to the name of the CMake package providing the custom implementation.
+USD must be able to locate a package with that name via a call to `find_package(${PXR_WORK_IMPL}` CONFIG)`, which
+may require specifying additional CMake variables. The package must provide a library target named
+`${PXR_WORK_IMPL}::${PXR_WORK_IMPL}` that specifies interface definitions (include directories, shared libraries,
+etc.) needed to use that library. The library must implement the required functions and classes and have a header
+named `impl.h` that supplies their declarations (either directly or in header files included in `impl.h`). This
+header must be able to be included via `#include <${PXR_WORK_IMPL}/impl.h>`.
+
+For example, a custom work implementation named `workExample` must provide a `workExampleConfig.cmake` file
+specifying a library target named `workExample::workExample`. This library must at minimum provide an `impl.h`
+header with the required implementations and set up interface include directories so that the header can
+be located via an include statement like `#include <workExample/impl.h>`.
+
 ##### Plugin Metadata Location
 
 Each library in the USD core generally has an associated file named 'plugInfo.json' that contains metadata about that library,
