 1. Install the latest Qt SDK (and optionally, the Qt Creator IDE) from https://www.qt.io/download

 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 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`
-    * 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.
