 Though the ZIP file contains everything necessary to run Sideband, it is also recommended to install the Reticulum command line utilities separately, so that you can use commands like `rnstatus` and `rnsd` from the command line.

+# Creating Plugins
+
+Sideband features a flexible and extensible plugin system, that allows you to hook all kinds of control, status reporting, command execution and telemetry collection into the LXMF messaging system. Plugins can be created as either *Telemetry*, *Command* or *Service* plugins, for different use-cases.
+
+To create plugins for Sideband, you can find a variety of [code examples](https://github.com/markqvist/Sideband/tree/main/docs/example_plugins) in this repository, that you can use as a basis for writing your own plugins. The example plugins include:
+
+- [Custom telemetry](https://github.com/markqvist/Sideband/blob/main/docs/example_plugins/telemetry.py)
+- [Getting BME280 temperature, humidity and pressure](https://github.com/markqvist/Sideband/blob/main/docs/example_plugins/bme280_telemetry.py)
+- [Basic commands](https://github.com/markqvist/Sideband/blob/main/docs/example_plugins/basic.py)
+- [Location telemetry from GPSd on Linux](https://github.com/markqvist/Sideband/blob/main/docs/example_plugins/gpsd_location.py)
+- [Location telemetry from Windows Location Provider](https://github.com/markqvist/Sideband/blob/main/docs/example_plugins/windows_location.py)
+- [Getting statistics from your LXMF propagation node](https://github.com/markqvist/Sideband/blob/main/docs/example_plugins/lxmd_telemetry.py)
+- [Viewing cameras and streams](https://github.com/markqvist/Sideband/blob/main/docs/example_plugins/view.py)
+- [Fetching an XKCD comic](https://github.com/markqvist/Sideband/blob/main/docs/example_plugins/comic.py)
+- [Creating a service plugin](https://github.com/markqvist/Sideband/blob/main/docs/example_plugins/service.py)
+
+For creating telemetry plugins, Sideband includes 20+ built-in sensor types to chose from, for representing all kinds telemetry data. If none of those fit your needs, there is a `Custom` sensor type, that can include any kind of data.
+
+Command plugins allow you to define any kind of action or command to be run when receiving command messages from other LXMF clients. In the example directory, you will find various command plugin templates, for example for viewing security cameras or webcams through Sideband.
+
+Service plugins allow you to integrate any kind of service, bridge or other system into Sideband, and have that react to events or state changes in Sideband itself.

 # Paper Messaging Example
 
 You can try out the paper messaging functionality by using the following QR-code. It is a paper message sent to the LXMF address `6b3362bd2c1dbf87b66a85f79a8d8c75`. To be able to decrypt and read the message, you will need to import the following base32-encoded Reticulum Identity into the app:
