 This also means that Sideband operates differently than what you might be used to. It does not need a connection to a server on the Internet to function, and you do not have an account anywhere. Please read the Guide section included in the program, to get an understanding of how Sideband differs from other messaging systems.

 # Installation
 
+Sideband can run on most computing devices, but installation methods vary by device type and operating system. For installation instructions, please find the relevant section below.
+
 ## On Android
 
 For your Android devices, you can install Sideband through F-Droid, by adding the [Between the Borders Repo](https://reticulum.betweentheborders.com/fdroid/repo/), or you can download an [APK on the latest release](https://github.com/markqvist/Sideband/releases/latest) page. Both sources are signed with the same release keys, and can be used interchangably.

+## On Raspberry Pi
+
+You can install Sideband on all Raspberry Pi models that support 64-bit operating systems, and can run at least Python version 3.11. Since some of Sideband's dependencies don't have pre-built packages ready for 64-bit ARM processors yet, you'll need to install a few extra packages, that will allow building these while installing.
+
+Aditionally, the `pycodec2` package needs to be installed manually. I have provided a pre-built version, that you can download and install with a single command, or if you don't want to trust my pre-built version, you can [build and install it from source yourself](https://github.com/gregorias/pycodec2/blob/main/DEV.md).
+
+The install instructions below assume that you are installing Sideband on 64-bit Raspberry Pi OS (based on Debian Bookworm). If you're running something else on your Pi, you might need to modify some commands slightly. To install Sideband on Raspberry Pi, follow these steps:
+
+```bash
+# First of all, install the required dependencies:
+sudo apt install python3-pip python3-pyaudio python3-dev python3-cryptography build-essential libopusfile0 libsdl2-dev libavcodec-dev libavdevice-dev libavfilter-dev portaudio19-dev codec2 libcodec2-1.0 xclip xsel
+
+# If you don't want to compile pycodec2 yourself,
+# download the pre-compiled package provided here
+wget https://raw.githubusercontent.com/markqvist/Sideband/main/docs/utilities/pycodec2-3.0.1-cp311-cp311-linux_aarch64.whl
+
+# Install it:
+pip install ./pycodec2-3.0.1-cp311-cp311-linux_aarch64.whl --break-system-packages
+
+# You can now install Sideband
+pip install sbapp --break-system-packages
+
+# Restart your Raspberry Pi
+sudo reboot
+
+# Everything is ready! You can now run Sideband
+# from the terminal, or from the application menu

 When running Sideband for the first time, a default Reticulum configuration file will be created, if you don't already have one. If you don't have any existing Reticulum connectivity available locally, you may want to edit the file, located at `C:\Users\USERNAME\.reticulum\config` and manually add an interface that provides connectivity to a wider network. If you just want to connect over the Internet, you can add one of the public hubs on the [Reticulum Testnet](https://reticulum.network/connect.html).
