+## Installation
+
+```sh
+docker build -t hasufell/alpine-umurmur .
+```
+
+## Configuration
+
+All configuration variables (except channel configuration)
+from the [config file](https://code.google.com/p/umurmur/wiki/Configuring02x)
+can simply be set when starting the container via the `-e` switches. E.g.
+if you want to set `password = "abc";` in `umurmur.conf` you just pass
+`-e password=abc` to the `docker run` command.
+
+If you don't like the `-e`-foo just modify `config/umurmur.conf` and
+`config/channels.conf` in-place in this repository or mount them into
+the container from the host.
+
+### Channels
+
+Either modify `config/channels.conf` directly or mount your own `channels.conf`
+in from the host. It must be in the container at the location
+`/umurmurconfig/channels.conf`! So e.g.:
+
+```sh
+	-v /var/lib/umurmurconf/channels.conf:/umurmurconfig/channels.conf
+```
+
+### Certificates
+
+Mount in your private key and certificate from the host into the container,
+e.g. at `/etc/ssl/` and then pass the environment variables `certificate`
+and `private_key` to `docker run`.
+
+E.g.:
+
+```sh
+	-v /ets/ssl/mydomain:/etc/ssl/mydomain \
+	-e certificate=/etc/ssl/mydomain/foo.crt \
+	-e private_key=/etc/ssl/mydomain/foo.key
+```
+
+## Running
+
+A full command could look like this:
+
+```sh
+docker run -ti -d \
+	--name=umurmur \
+	-v /var/lib/umurmurconf/channels.conf:/umurmurconfig/channels.conf \
+	-v /ets/ssl/mydomain:/etc/ssl/mydomain \
+	-e certificate=/etc/ssl/mydomain/foo.crt \
+	-e private_key=/etc/ssl/mydomain/foo.key \
+	-e password=blah \
+	-e admin_password=foo \
+	-e username=murmur \
+	-e groupname=murmur \
+	-p 64738:64738 \
+	hasufell/alpine-umurmur
+```
