+## Building the Engine
+### Build Requirements and redistributables
+
+*   Visual Studio 2019 16.9.2 (All versions supported, including Community): [https://visualstudio.microsoft.com/downloads/](https://visualstudio.microsoft.com/downloads/)
+    *   Install the following workloads:
+        *   Game Development with C++
+        *   MSVC v142 - VS 2019 C++ x64/x86
+*   Visual C++ redistributable: [https://visualstudio.microsoft.com/downloads/#other-family](https://visualstudio.microsoft.com/downloads/#other-family)
+*   FBXSDK for VS2015: [https://www.autodesk.com/developer-network/platform-technologies/fbx-sdk-2016-1-2](https://www.autodesk.com/developer-network/platform-technologies/fbx-sdk-2016-1-2)
+*   WWise - 2019.2.8.7432: [https://www.audiokinetic.com/download/](https://www.audiokinetic.com/download/)
+*   CMake 3.19.1: [https://cmake.org/files/LatestRelease/cmake-3.19.1-win64-x64.msi](https://cmake.org/files/LatestRelease/cmake-3.19.1-win64-x64.msi)
+
+### Build Steps
+
+1.  Download the 3rdParty zip file from here: **[https://d2c171ws20a1rv.cloudfront.net/3rdParty-windows-no-symbols-rev7.zip](https://d2c171ws20a1rv.cloudfront.net/3rdParty-windows-no-symbols-rev7.zip)**
+2.  Unzip this file into a writable folder. This will also act as a cache location for the 3rdParty downloader by default (configurable with the `LY_PACKAGE_DOWNLOAD_CACHE_LOCATION` environment variable)
+3.  Install the following redistributables to the following:
+    - Visual Studio and VC++ redistributable can be installed to any location
+    - FBXSDK should be installed to `<3rdParty path>\FbxSdk\2016.1.2-az.1`. See the README in this folder for details
+    - WWise should be installed to: `<3rdParty Path>\Wwise\2019.2.8.7432`
+    - CMake should be installed to: `<3rdParty Path>\CMake\3.19.1`
+4.  Add the following environment variables through the command line
+    ```
+    set LY_3RDPARTY_PATH=<Location of the unzipped 3rdParty zip>
+    set LY_PACKAGE_SERVER_URLS="https://d2c171ws20a1rv.cloudfront.net"
+    ```
+    
+5.  Configure the source into a solution using this command line, replacing <your build location> to a path you've created
+    ```
+    cmake -B <your build location> -S <source-dir> -G "Visual Studio 16 2019" -DLY_3RDPARTY_PATH=%LY_3RDPARTY_PATH% -DLY_UNITY_BUILD=ON -DLY_PROJECTS=AutomatedTesting -DLY_MONOLITHIC_GAME=1
+    ```
+
+6.  Alternatively, you can do this through the CMake GUI:
+    
+    1.  Start `cmake-gui.exe`
+    2.  Select the local path of the repo under "Where is the source code"
+    3.  Select a path where to build binaries under "Where to build the binaries"
+    4.  Click "Configure"
+    5.  Wait for the key values to populate. Fill in the fields that are relevant, including `LY_3RDPARTY_PATH`, `LY_PACKAGE_SERVER_URLS`, and `LY_PROJECTS`
+    6.  Click "Generate"
+    
+7.  The configuration of the solution is complete. To build the Editor and AssetProcessor to binaries, run this command inside your repo:
+    ```
+    cmake --build <your build location> --target AutomatedTesting.GameLauncher AssetProcessor Editor --config profile -- /m
+    ```
+   
+8.  This will compile after some time and binaries will be available in the build path you've specified
+
+### Setting up new projects    
+1. Setup new projects using this command
+    ```
+    <Repo path>\scripts\o3de.bat create-project --project-path <New project path>
+    ```
+2.  Once you're ready to build the project, run the same set of commands to configure and build:
+    ```
+    cmake -B <your build location> -S <source-dir> -G "Visual Studio 16 2019" -DLY_3RDPARTY_PATH=%LY_3RDPARTY_PATH% -DLY_PROJECTS=<New project name> -DLY_MONOLITHIC_GAME=1
+
+    cmake --build <your build location> --target <New Project Name> --config profile -- /m
+    ```
