 ## HttpStress
 
-Provides stress testing scenaria for System.Net.Http.HttpClient, with emphasis on the HTTP/2 implementation of SocketsHttpHandler.
+Provides stress testing scenaria for System.Net.Http.HttpClient and the underlying SocketsHttpHandler.
 
 ### Running the suite locally
 
-Using the command line,
+Prerequisite: the runtime and the libraries should be [live-built](https://github.com/dotnet/runtime/tree/main/docs/workflow/building/libraries) with `build.cmd`/`build.sh`.
+
+Use the script `build-local.sh` / `build-local.ps1` to build the stress project against the live-built runtime. This will acquire the latest daily SDK, which is TFM-compatible with the live-built runtime.
+
+```bash
+$ build-local.sh [StressConfiguration] [LibrariesConfiguration]
+```
+
+The build script will also generate the runscript that runs the stress suite using the locally built testhost in the form of `run-stress-<StressConfiguration>-<LirariesConfiguration>.sh`. To run the tests with the script, assuming that both the stress project and the libraries have been built against Release configuration:
 
 ```bash
-$ dotnet run -- <stress suite args>
+$ run-stress-Release-Release.sh [stress suite args]
 ```
 
 To get the full list of available parameters:
 
 ```bash
-$ dotnet run -- -help
+$ run-stress-Release-Release.sh -help
 ```
 
-### Running with local runtime builds
+### Building and running with Docker
 
-Note that the stress suite will test the sdk available in the environment,
-that is to say it will not necessarily test the implementation of the local runtime repo.
-To achieve this, we will first need to build a new sdk from source. This can be done [using docker](https://github.com/dotnet/runtime/blob/main/eng/docker/Readme.md).
+A docker image containing the live-built runtime bits and the latest daily SDK is created with the [`build-docker-sdk.sh/ps1` scripts](https://github.com/dotnet/runtime/blob/main/eng/docker/Readme.md).
 
-### Running using docker-compose
+It's possible to manually `docker build` a docker image containing the stress project based on the docker image created with `build-docker-sdk.sh/ps1`, however the preferred way is to use docker-compose, which can be used to target both linux and windows containers.
 
-The preferred way of running the stress suite is using docker-compose,
-which can be used to target both linux and windows containers.
 Docker and compose-compose are required for this step (both included in [docker for windows](https://docs.docker.com/docker-for-windows/)).

 ### Running the suite locally
 
-Using the command line,
+Prerequisite: the runtime and the libraries should be [live-built](https://github.com/dotnet/runtime/tree/main/docs/workflow/building/libraries) with `build.cmd`/`build.sh`.
+
+Use the script `build-local.sh` / `Build-Local.ps1` to build the stress project against the live-built runtime.
+
+```bash
+$ build-local.sh [StressConfiguration] [LibrariesConfiguration]
+```
+
+The build script will also generate the runscript that runs the stress suite using the locally built testhost in the form of `run-stress-<StressConfiguration>-<LirariesConfiguration>.sh`. To run the tests with the script, assuming that both the stress project and the libraries have been built against Release configuration:
 
 ```bash
-$ dotnet run -- <stress suite args>
+$ run-stress-Release-Release.sh [stress suite args]
 ```
 
 To get the full list of available parameters:
 
 ```bash
-$ dotnet run -- -help
+$ run-stress-Release-Release.sh.sh -help
 ```
 
-### Running with local runtime builds
+### Building and running with Docker
 
-Note that the stress suite will test the sdk available in the environment,
-that is to say it will not necessarily test the implementation of the local runtime repo.
-To achieve this, we will first need to build a new sdk from source. This can be done [using docker](https://github.com/dotnet/runtime/blob/main/eng/docker/Readme.md).
+A docker image containing the live-built runtime bits and the latest daily SDK is created with the [`build-docker-sdk.sh/ps1` scripts](https://github.com/dotnet/runtime/blob/main/eng/docker/Readme.md).
 
-### Running using docker-compose
+It's possible to manually `docker build` a docker image containing the stress project based on the docker image created with `build-docker-sdk.sh/ps1`, however the preferred way is to use docker-compose, which can be used to target both linux and windows containers.
 
-The preferred way of running the stress suite is using docker-compose,
