+A container for the motsognir gopher server http://motsognir.sourceforge.net/
+
+## Running locally
+
+**x86_64**
+
+```
+$> docker run -p 70:70 -v /path/to/you/local/gopherfolder:/gopher dragonchaser/motsognir:latest 
+```
+
+**arm32v7**
+
+```
+$> docker run -p 70:70 -v /path/to/you/local/gopherfolder:/gopher dragonchaser/motsognir:latest-arm32v7 
+```
+
+**Notes:** 
+- `motsognir.conf` needs to live in `/gopher`
+- I suggest serving files from a subdirectory of `/gopher`
+- I suggest also to use the `gopher` user in the `RunAsUser` variable in `/gopher/motsognir.conf`
+- the container uses a bare minimal of an operating system needed to run
+  motsognir, for debugging it might make sense to run `apt-get install procps`
+  in the container
