 # docker-rpi-homebridge
-Work in progress Docker image for running homebridge on a Raspberry Pi
+Docker image for running [Homebridge](https://github.com/nfarina/homebridge) on a Raspberry Pi
+
+## Homebridge
+Here is what the author has to say about Homebridge:
+
+> Homebridge is a lightweight NodeJS server you can run on your home network that emulates the iOS HomeKit API. It supports Plugins, which are community-contributed modules that provide a basic bridge from HomeKit to various 3rd-party APIs provided by manufacturers of "smart home" devices.
+
+This project is just a Docker container that makes it easy to deploy Homebridge on your Raspberry Pi.
+
+## Getting Docker on your Raspberry Pi
+I recommend checking out [Hypriot](http://blog.hypriot.com/) and their [Getting Started](http://blog.hypriot.com/getting-started-with-docker-on-your-arm-device/) guide
+
+## Configuration
+There are two files that need to be provided in order for Homebridge to run.
+
+ * `config.json`: For a quick start, you can copy `config-sample.json` and modify it to your needs. For detailed explanation of this file, check out the [documentation](https://github.com/nfarina/homebridge#installation) provided by Homebridge
+ * `plugins.txt`: in order to do anything, Homebridge needs to install plugins for your accessories and platforms. You can list them here with each npm package on a new line. See `plugins-sample.txt` for an example and, again, check out the [documentation](https://github.com/nfarina/homebridge#installing-plugins) provided by Homebridge for more details.
+
+## Running
+This image is hosted on Docker Hub tagged as [vividboarder/rpi-homebridge](https://hub.docker.com/r/vividboarder/rpi-homebridge/), so you can feel free to use the `docker-compose.yaml` and change `build: .` to `image: vividboarder/rpi-homebridge`. After that, `docker-compose up` should get you started.
+
+Alternately, you can compile the image yourself by cloning this repo and using `docker-compose`
+
+```
+docker-compose up
+```
+
+If you want a little more control, you can use any of the make targets:
+
+```
+make build  # builds a new image
+make run    # builds and runs container using same parameters as compose
+make shell  # builds and runs an interractive container
+make tag    # tags image to be pushed to docker hub
+make push   # pushes image to docker hub
+```
