> +# EmulatorPkg - Platform CI
> +
> +This ReadMe.md describes the Azure DevOps based Platform CI for EmulatorPkg and how
> +to use the same Pytools based build infrastructure locally.
> +
> +## Supported Configuration Details
> +
> +This solution for building and running EmulatorPkg has only been validated with Windows 10
> +with VS2019 and Ubuntu 18.04 with GCC5 toolchain. Two different firmware builds are
> +supported and are described below.

> +## Building with Pytools for EmulatorPkg
> +
> +1. [Optional] Create a Python Virtual Environment - generally once per workspace
> +
> +    ``` bash
> +    python -m venv <name of virtual environment>
> +    ```
> +
> +2. [Optional] Activate Virtual Environment - each time new shell opened
> +    - Linux
> +
> +      ```bash
> +      source <name of virtual environment>/bin/activate
> +      ```
> +
> +    - Windows
> +
> +      ``` bash
> +      <name of virtual environment>/Scripts/activate.bat
> +      ```
> +
> +3. Install Pytools - generally once per virtual env or whenever pip-requirements.txt changes
> +
> +    ``` bash
> +    pip install --upgrade -r pip-requirements.txt
> +    ```
> +
> +4. Initialize & Update Submodules - only when submodules updated
> +
> +    ``` bash
> +    stuart_setup -c EmulatorPkg/PlatformCI/PlatformBuild.py TOOL_CHAIN_TAG=<TOOL_CHAIN_TAG> -a <TARGET_ARCH>
> +    ```
> +
> +5. Initialize & Update Dependencies - only as needed when ext_deps change
> +
> +    ``` bash
> +    stuart_update -c EmulatorPkg/PlatformCI/PlatformBuild.py TOOL_CHAIN_TAG=<TOOL_CHAIN_TAG> -a <TARGET_ARCH>
> +    ```
> +
> +6. Compile the basetools if necessary - only when basetools C source files change
> +
> +    ``` bash
> +    python BaseTools/Edk2ToolsBuild.py -t <ToolChainTag>
> +    ```
> +
> +7. Compile Firmware
> +
> +    ``` bash
> +    stuart_build -c EmulatorPkg/PlatformCI/PlatformBuild.py TOOL_CHAIN_TAG=<TOOL_CHAIN_TAG> -a <TARGET_ARCH>
> +    ```
> +
> +    - use `stuart_build -c EmulatorPkg/PlatformCI/PlatformBuild.py -h` option to see additional
> +    options like `--clean`
> +
> +8. Running Emulator
> +    - You can add `--FlashRom` to the end of your build command and the emulator will run after the
> +    build is complete.
> +    - or use the `--FlashOnly` feature to just run the emulator.
> +
> +      ``` bash
> +      stuart_build -c EmulatorPkg/PlatformCI/PlatformBuild.py TOOL_CHAIN_TAG=<TOOL_CHAIN_TAG> -a <TARGET_ARCH> --
> FlashOnly
> +      ```
> +
> +### Notes
> +
> +1. Configuring *ACTIVE_PLATFORM* and *TARGET_ARCH* in Conf/target.txt is **not** required. This
> +   environment is set by PlatformBuild.py based upon the `[-a <TARGET_ARCH>]` parameter.
> +
> +**NOTE:** Logging the execution output will be in the normal stuart log as well as to your console.
> +
> +### Custom Build Options
> +
> +**MAKE_STARTUP_NSH=TRUE** will output a *startup.nsh* file to the location mapped as fs0. This is
> +used in CI in combination with the `--FlashOnly` feature to run the Emulator to the UEFI shell and then execute
> +the contents of *startup.nsh*.
> +
> +### Passing Build Defines
> +
> +To pass build defines through _stuart_build_, prepend `BLD_*_`to the define name and pass it on the
> +command-line. _stuart_build_ currently requires values to be assigned, so add an`=1` suffix for bare defines.
> +For example, to enable the IP6 Network Stack, the stuart_build command-line would be:
> +
> +`stuart_build -c EmulatorPkg/PlatformCI/PlatformBuild.py BLD_*_NETWORK_IP6_ENABLE=1`
