+### Docker image
+
+Those tools are also availble as a Docker image from
+[dockerhub](https://hub.docker.com/r/pelletier/go-toml). For example, to
+use `tomljson`:
+
+```
+docker run -v $PWD:/workdir pelletier/go-toml tomljson /workdir/example.toml
+```
+
+Only master (`latest`) and tagged versions are published to dockerhub. You
+can build your own image as usual:
+
+```
+docker build -t go-toml .
+```
