-**5\.** Install the appropriate 1.6 Freedesktop Platform/SDK for your CPU architecture:
+**5\.** Invoke the build command to build for your CPU architecture:
 
 ```bash
-flatpak --user install --no-related flathub "org.freedesktop.Platform/$(flatpak --default-arch)/1.6"
-flatpak --user install --no-related flathub "org.freedesktop.Sdk/$(flatpak --default-arch)/1.6"

-**6\.** This step is not mandatory, but highly recommended for `x86_64` users (`aarch64` users should skip this):
-
-It's about building the `i386` driver, which is necessary for 32-bit 3D apps and games to work.
-
-If you want to proceed, [these steps](https://github.com/guihkx/freedesktop-sdk-1.6-i386/releases/latest) will guide you on how to download and set up a third-party build (because it's not available on Flathub anymore) of the i386 1.6 Freedesktop SDK.
-
-Once you finish doing that, you can continue following the steps below.

-
-```bash
-make ARCH=i386 FB_ARGS='--user'
-flatpak build-update-repo --no-summary-index repo/
