 This is the default OS that is provided by the Raspberry Pi foundation and comes preinstalled on the micro SD card that the Hackberry ships with.

+If you mount the micro SD card on a computer, it will be located on the ''bootfs'' partition under ''/firmware/config.txt''.\\ If you want to edit the file on a running Raspberry Pi (either through SSH or by attaching an external display via HDMI), it will be located under ''/boot/firmware/config.txt''.
+Screen blanking should be disabled by default, but it is never a bad idea to manually disable it by running ''sudo raspi-config'' and navigating to //Display Options > Screen Blanking.//

 The following image is a clean install of Raspberry Pi OS. It comes with a configured ''config.txt'' to enable the display. Furthermore, it comes with Pi-Apps and Alacritty preinstalled. It also includes the battery voltage script.\\

+=== External Display ===
+If you fail to get an external display working, make sure you're using Wayland. \\
+To do so, run ''sudo raspi-config'' and go to //Advanced Options > Wayland// and choose //Wayfire//, then reboot. The display should now be recognized and work automatically. \\
+Use the Screen Configuration application to configure the orientation and arrangement.
+===== SDR++ =====
+It is recommended to install SDR++ by compiling it from source.
+Do the following:
+<code>
+# Install dependencies
+sudo apt install git cmake libfftw3-dev libglfw3-dev libvolk2-dev libglew-dev portaudio19-dev libzstd1 libzstd-dev libairspyhf-dev libiio-dev libad9361-dev libairspy-dev librtlsdr-dev libcodec2-dev librtaudio-dev libhackrf-dev
+# Download the code
+cd ~/Downloads
+git clone https://github.com/AlexandreRouma/SDRPlusPlus.git
+# Build
+cd SDRPlusPlus
+mkdir build
+cd build
+cmake ..
+make -j4
+# Install
+sudo make install
+</code>
+You can now run SDR++ from the applications' menu or from the terminal with ''sdrpp''.\\
+Make sure you're connected to the bluetooth speakers or any other audio device. In SDR++, scroll down to the Sinks tab, make sure the right audio device is selected, and set the bitrate to 44100.
