+# ControlPi Plugin for Pi Camera Module
+This distribution package contains a plugin for the
+[ControlPi system](https://docs.graph-it.com/graphit/controlpi), that
+uses a connected Pi camera module to create snapshots at configurable
+intervals and announce them on the message bus.
+
+Documentation (in German) can be found at [doc/index.md](doc/index.md) in
+the source repository and at
+[https://docs.graph-it.com/graphit/controlpi-camera/](https://docs.graph-it.com/graphit/controlpi-camera/).
+Code documentation (in English) including doctests is contained in the
+source files.
+An API documentation generated by pdoc3 can be found at
+[doc/controlpi_plugins/index.html](doc/controlpi_plugins/index.html) in the source
+repository and at
+[https://docs.graph-it.com/graphit/controlpi-camera/controlpi_plugins/](https://docs.graph-it.com/graphit/controlpi-camera/controlpi_plugins/).

+# ControlPi-Plugin für Pi-Camera-Modul
+Dieses Paket enthält ein Plugin für das ControlPi-System, mit dem
+Einzelbilder eines angeschlossenen Pi-Camera-Modul regelmäßig in einem
+gegegebenen Pfad abgelegt werden können.
+
+## Installation
+Eine ausführliche Dokumentation ist in der Dokumentation der
+[ControlPi-Infrastruktur](https://docs.graph-it.com/graphit/controlpi) zu
+finden.
+
+Der Code dieses Plugins kann mit git geclonet werden:
+```sh
+$ git clone git://git.graph-it.com/graphit/controlpi-camera.git
+```
+(Falls Zugang zu diesem Server per SSH besteht und Änderungen gepusht
+werden sollen, sollte stattdessen die SSH-URL benutzt werden.)
+
+Dann kann es editierbar in ein virtuelles Environment installiert werden:
+```sh
+(venv)$ pip install --editable <Pfad zum Code-Repository>
+```
+
+Auf dem Raspberry Pi (oder wenn keine Code-Änderungen gewünscht sind) kann
+es auch direkt, ohne einen git-Clone installiert werden:
+```sh
+(venv)$ pip install git+git://git.graph-it.com/graphit/controlpi-camera.git
+```
