 * GCC or Clang

 * FFmpeg 4.0 is required to build. If your distro doesn't package FFmpeg 4.0, you can build and install it from source on http://ffmpeg.org/
 
+### Steam Link-specific Build Requirements
+* [Steam Link SDK](https://github.com/ValveSoftware/steamlink-sdk) cloned on your build system
+* STEAMLINK_SDK_PATH environment variable set to the Steam Link SDK path
+
 ### Build Setup Steps
 1. Install the latest Qt SDK (and optionally, the Qt Creator IDE) from https://www.qt.io/download
     * You can install Qt via Homebrew on macOS, but you will need to use `brew install qt --with-debug` to be able to create debug builds of Moonlight.
     * You may also use your Linux distro's package manager for the Qt SDK as long as the packages are Qt 5.9 or later.
+    * This step is not required for building on Steam Link, because the Steam Link SDK includes Qt 5.9.
 2. Run `git submodule update --init --recursive` from within `moonlight-qt/`
 3. Open the project in Qt Creator or build from qmake on the command line.
     * To build a binary for use on non-development machines, use the scripts in the `scripts` folder.
         * For Windows builds, use `scripts\generate-installers.bat`. Execute this script from the root of the repository within a Qt command prompt. Ensure WiX and 7-Zip binary directories are in your `%PATH%`.
         * For macOS builds, use `scripts/generate-dmg.sh`. Execute this script from the root of the repository and ensure Qt's `bin` folder is in your `$PATH`.
+        * For Steam Link builds, run `scripts/build-steamlink-app.sh` from the root of the repository.
     * To build from the command line for development use, run `qmake moonlight-qt.pro` then `make debug` or `make release`
