+**READ ME FIRST!**
+If you're here because something basic is not working (like gamepad input, video, or similar), it's probably something specific to your setup, so make sure you've gone through the Troubleshooting Guide first: https://github.com/moonlight-stream/moonlight-docs/wiki/Troubleshooting
+
+If you still have trouble with basic functionality after following the guide, join our Discord server where there are many other volunteers who can help (or direct you back here if it looks like a Moonlight bug after all). https://moonlight-stream.org/discord

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

-### Windows-specific Requirements
-* Windows 7 or later
-* Visual Studio 2015 or later
-* 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)
+### Windows Build Requirements
+* Qt 6.7 SDK or later (earlier versions may work but are not officially supported)
+* [Visual Studio 2022](https://visualstudio.microsoft.com/downloads/) (Community edition is fine)
+* Select **MSVC** option during Qt installation. MinGW is not supported.
+* [7-Zip](https://www.7-zip.org/) (only if building installers for non-development PCs)
+* Graphics Tools (only if running debug builds)
+  * Install "Graphics Tools" in the Optional Features page of the Windows Settings app.
+  * Alternatively, run `dism /online /add-capability /capabilityname:Tools.Graphics.DirectX~~~~0.0.1.0` and reboot.

-### 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 6.7 SDK or later (earlier versions may work but are not officially supported)
+* Xcode 14 or later (earlier versions may work but are not officially supported)
 * [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 6 is recommended, but Qt 5.12 or later is also supported (replace `qmake6` with `qmake` when using Qt 5).
 * 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`
-* 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/
+* FFmpeg 4.0 or later
+* Install the required packages:
+  * Debian/Ubuntu:
+    * Base Requirements: `libegl1-mesa-dev libgl1-mesa-dev libopus-dev libsdl2-dev libsdl2-ttf-dev libssl-dev libavcodec-dev libavformat-dev libswscale-dev libva-dev libvdpau-dev libxkbcommon-dev wayland-protocols libdrm-dev`
+    * Qt 6 (Recommended): `qt6-base-dev qt6-declarative-dev libqt6svg6-dev qt6-wayland qml6-module-qtquick-controls qml6-module-qtquick-templates qml6-module-qtquick-layouts qml6-module-qtqml-workerscript qml6-module-qtquick-window qml6-module-qtquick`
+    * Qt 5: `qtbase5-dev qt5-qmake qtdeclarative5-dev qtquickcontrols2-5-dev qml-module-qtquick-controls2 qml-module-qtquick-layouts qml-module-qtquick-window2 qml-module-qtquick2 qtwayland5`
+  * RedHat/Fedora (RPM Fusion repo required):
+    * Base Requirements: `openssl-devel SDL2-devel SDL2_ttf-devel ffmpeg-devel libva-devel libvdpau-devel opus-devel pulseaudio-libs-devel alsa-lib-devel libdrm-devel`
+    * Qt 6 (Recommended): `qt6-qtsvg-devel qt6-qtdeclarative-devel`
+    * Qt 5: `qt5-qtsvg-devel qt5-qtquickcontrols2-devel`
+* Building the Vulkan renderer requires a `libplacebo-dev`/`libplacebo-devel` version of at least v7.349.0 and FFmpeg 6.1 or later.
+
+### 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
+
+**Steam Link Hardware Limitations**  
+Moonlight builds for Steam Link are subject to hardware limitations of the Steam Link device:
+* Maximum resolution: **1080p (1920x1080)**
+* Maximum framerate: **60 FPS**
+* Maximum video bitrate: **40 Mbps**
+* **HDR streaming is not supported** on the original hardware
+
+### Docker containers
+If you want to use Docker for building, look at [this repo](https://github.com/cgutman/moonlight-packaging) containing canonical containers
+for different architectures, which handle building deps and extra linking for you.

 ### 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.
-2. Run `git submodule update --init --recursive` from within `moonlight-qt/`
+    * 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 5.12 or later.
+    * This step is not required for building on Steam Link, because the Steam Link SDK includes Qt 5.14.
+2. Download submodules and dependencies
+    * Run `git submodule update --init --recursive` from within `moonlight-qt/`.
+    * On Windows and macOS, you must also run `setup-deps.ps1` (Windows) or `setup-deps.py` (macOS).
+    * Perform these steps each time you pull new changes from the Git repository.
 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 Windows builds, use `scripts\build-arch.bat` and `scripts\generate-bundle.bat`. Execute these scripts from the root of the repository within a Qt command prompt. Ensure  7-Zip binary directory is on 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 on macOS or Linux, run `qmake6 moonlight-qt.pro` then `make debug` or `make release`.
+        * The final binary will be placed in `app/moonlight`.
+    * To create an embedded build for a single-purpose device, use `qmake6 "CONFIG+=embedded" moonlight-qt.pro` and build normally.
+        * This build will lack windowed mode, Discord/Help links, and other features that don't make sense on an embedded device.
+        * For platforms with poor GPU performance, add `"CONFIG+=gpuslow"` to prefer direct KMSDRM rendering over GL/Vulkan renderers. Direct KMSDRM rendering can use dedicated YUV/RGB conversion and scaling hardware rather than slower GPU shaders for these operations.
