 ### Setting up
  * ``mkdir build`` & ``cd build`` in the root of the plugin folder.
  * Open the [MSVC developer console](https://learn.microsoft.com/en-us/cpp/build/building-on-the-command-line) with the correct platform (x86 or x86_64) that you plan on targetting.
- * Run ``python3 ../configure.py --plugin-name={PLUGIN_NAME} --plugin-alias={PLUGIN_ALIAS} -s {SDKNAME} --targets={TARGET} --mms_path={MMS_PATH} --hl2sdk-root {HL2SDKROOT} `` where:
+ * Run ``python3 ../configure.py --plugin-name={PLUGIN_NAME} --plugin-alias={PLUGIN_ALIAS} -s {SDKNAME} --targets={TARGET} --mms_path={MMS_PATH} --hl2sdk-root {HL2SDKROOT} --hl2sdk-manifests {HL2SDKMANIFESTS} `` where:
    * ``{PLUGIN_NAME}`` should be the plugin name which is used for the resulting binary name and folder naming scheme (this doesn't affect the plugin name you'd see in the plugin list if you don't modify the base plugin functions);
    * ``{PLUGIN_ALIAS}`` should be used to set the plugin alias that is used as a short hand version to load, unload, list info etc via the metamod-source menu (example being ``meta unload sample``, where ``sample`` is the alias);
    * ``{SDKNAME}`` should be the hl2sdk game name that you are building for;
    * ``{TARGET}`` should be the target platform you are targeting (``x86`` or ``x86_64``);
    * ``{MMS_PATH}`` should point to the root of the metamod-source folder;
-   * ``{HL2SDKROOT}`` should point to the root of the hl2sdk's folders, note that it should not point to the actual ``hl2sdk-GAME`` folder but a root parent of it;
+   * ``{HL2SDKROOT}`` should point to the root of the hl2sdk's folders, note that it should **not** point to the actual ``hl2sdk-GAME`` folder but a root parent of it;
+   * ``{HL2SDKMANIFESTS}`` should point to the root of a clone of the https://github.com/alliedmodders/hl2sdk-manifests repository. It is suggested that you use a submodule for this, as this folder must live within your project for AMBuild to be able to consume the helper script within;
    * Alternatively ``{MMS_PATH}`` & ``{HL2SDKROOT}`` could be put as a ``PATH`` environment variables, like ``MMSOURCE112=D:\mmsource-1.12`` & ``HL2SDKCS2=D:\hl2sdks\hl2sdk-cs2`` (note the metamod version and that here hl2sdk environment variable should point directly to the game's hl2sdk folder and not to the root of it!)
    * Example: ``python3 ../configure.py --plugin-name=sample_mm --plugin-alias=sample -s cs2 --targets=x86_64 --mms_path=D:\mmsource-1.12 --hl2sdk-root=D:\hl2sdks``
  * If the process of configuring was successful, you should be able to run ``ambuild`` in the ``\build`` folder to compile the plugin.
