+* FFmpeg 4.0 or later is required to build. If your distro doesn't package FFmpeg 4.0 or later, you can build and install it from source on https://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
 
-**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 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.
+    * 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 5.14.
-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.
+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\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.
+    * To build from the command line for development use on macOS or Linux, run `qmake moonlight-qt.pro` then `make debug` or `make release`
+    * To create an embedded build for a single-purpose device, use `qmake "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.
+        * For platforms with poor GL performance, add `"CONFIG+=glslow"` to prefer direct KMSDRM rendering over EGL/GLES renderers. Direct KMSDRM rendering can use dedicated YUV/RGB conversion and scaling hardware rather than slower GPU shaders for these operations.

-				<ul>
-					<li>Ctrl+Alt+Shift+K has been added to toggle system keyboard grab</li>
-					<li>Added support for DualSense adaptive triggers (requires a compatible host)</li>
-					<li>Gamepads with a second trackpad can now be passed to the host (requires host support)</li>

-					<li>The cursor is now also locked to the video area in single display borderless windowed scenarios. This was previously only done in true full-screen mode.</li>
-					<li>The cursor is no longer captured by default in windowed mode. Clicking on the streaming window or pressing Ctrl+Alt+Shift+Z will capture the cursor.</li>
-					<li>GPUs on non-x86 Linux platforms are now assumed to be slow by default, which enables a number of optimizations for improved performance. GL_IS_SLOW=0/VULKAN_IS_SLOW=0 can be set at runtime to override this.</li>

-					<li>Video bitrate no longer resets when adjusting resolution or frame rate if it's already been manually adjusted</li>
-				</ul>

-					<li>Fixed broken overlay rendering on PowerVR systems using the proprietary driver</li>
-					<li>Fixed automatic selection of AV1 on systems where HEVC is not available</li>
-					<li>Fixed instability when using VAAPI decoding under X11</li>
-					<li>Fixed small deviations in chroma co-siting and color conversion</li>
-					<li>Fixed suboptimal format selection on some V4L2 decoders</li>
-					<li>Fixed handling of some non-US keyboard layouts</li>
-					<li>Fixed stale app list being displayed when using CLI commands</li>
-					<li>Fixed handling of IPv6 literals that are not URL-escaped</li>
-					<li>Fixed AV1 Vulkan Video decoding on newer versions of FFmpeg</li>
-					<li>Fixed Ctrl+C/SIGTERM when running from the console</li>
-					<li>Fixed several GUI interoperability issues with Qt 6.9 and later</li>
-					<li>Fixed the IME or software keyboard being unexpectedly displayed in various situations</li>
-					<li>Fixed launching in a new VT while a Wayland compositor is running</li>
-					<li>Fixed moving focus from the app grid into the toolbar via the gamepad or keyboard</li>
-					<li>Fixed a possible crash in the Vulkan renderer when disabling an overlay</li>
-					<li>Fixed keyboard grab not working under sdl2-compat on Wayland compositors that lack support for keyboard-shortcuts-inhibit-unstable-v1</li>
-					<li>Fixed CLI stream launch causing the saved manual address to be overwritten</li>
-					<li>Fixed distinguishing between Enter and Numpad Enter keys (requires updated host software)</li>
-					<li>Fixed mDNS discovering unexpected devices after running for a period of time</li>
-					<li>Fixed libdecor-gtk window decorations not being displayed on the streaming window</li>
-					<li>Updated community-contributed translations from Weblate</li>
