+## Building for Multithreaded packages
+
+This is a work in progress and far from functional.  Currentlty there exists just enough infrastucture to build packages for mutlithreaded runtime and libs, but they are not functional in the sense that they support multithreaded programs yet.  To build the WASI packages:
+```
+build clr.aot+libs+nativeaot.packages -c Debug -a wasm -os wasi -cmakeargs -DCLR_CMAKE_TARGET_OS_SUBGROUP=multithread '/p:WasmEnableThreads=true'
+```
+To build the browser multithreaded packages:
+```
+build clr.aot+libs+nativeaot.packages -c Debug -a wasm -os browser -cmakeargs -DCLR_CMAKE_TARGET_OS_SUBGROUP=multithread '/p:WasmEnableThreads=true'
+```
+To build the runtime tests for WASI
+```
+src\tests\build nativeaot Debug wasm tree nativeaot wasi /p:LibrariesConfiguration=debug /p:TestWrapperTargetsWindows=true /p:FeatureWasmManagedThreads=true
+```
+To build the runtime tests for browser
+```
+src\tests\build nativeaot Debug wasm tree nativeaot browser /p:LibrariesConfiguration=debug /p:TestWrapperTargetsWindows=true /p:FeatureWasmManagedThreads=true /p:WasmEnableThreads=true

 ### Using built binaries
 
 In this workflow, you have a project file that you want to `dotnet publish`, but you want to use your own build of the compiler/runtime/framework. You need to be using a daily build of the .NET SDK downloaded from the dotnet/sdk repo. It's typically enough to just download the daily build ZIP file, unpack it, and make sure the unpacked directory is the first thing in your PATH. Don't forget to add a NuGet.config as specified by the dotnet/sdk repo- you'll hit restore issues otherwise.
