 ## Building
-### General Build Requirements
-* Qt 5.9 SDK or later

-### Windows-specific Requirements
+### Windows Build Requirements
+* Qt 5.12.4 SDK or later
 * Windows 7 or later
-* Visual Studio 2015 or later
+* [Visual Studio](https://visualstudio.microsoft.com/downloads/) 2017 (Community edition is fine)
 * Select MSVC Desktop toolchain during Qt installation
-* 7-Zip (only if building installers for non-development PCs)
-* WiX Toolset v3.11 or later (only if building installers for non-development PCs)
+* [DirectX SDK](https://www.microsoft.com/en-us/download/details.aspx?id=6812)
+* [7-Zip](https://www.7-zip.org/) (only if building installers for non-development PCs)
+* [WiX Toolset](http://wixtoolset.org/releases/) v3.11 or later (only if building installers for non-development PCs)

-### Mac-specific Requirements
-* macOS El Capitan (10.11) or later
-* Xcode with High Sierra (10.13) SDK (Mojave SDK not yet supported until Qt 5.12 later this year)
+### macOS Build Requirements
+* Qt 5.14 SDK or later
+* macOS High Sierra (10.13) or later
+* Xcode 11
 * [create-dmg](https://github.com/sindresorhus/create-dmg) (only if building DMGs for use on non-development Macs)

-### Linux-specific Requirements
+### Linux/Unix Build Requirements
+* Qt 5.9 SDK or later
 * GCC or Clang
-* Install your distro equivalents of: `openssl-devel qt5-devel SDL2-devel ffmpeg-devel qt5-qtquickcontrols2-devel libva-devel libvdpau-devel opus-devel`
+* Install your distro equivalents of: `openssl-devel qt5-devel SDL2-devel ffmpeg-devel qt5-qtquickcontrols2-devel libva-devel libvdpau-devel opus-devel pulseaudio-libs-devel alsa-lib-devel SDL2_ttf-devel`
 * 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 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 may also use Homebrew on macOS or your Linux distro's package manager for the Qt SDK as long as the packages are Qt 5.9 or later.
+    * 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`
