+If you are interested in wrapping the dehyrdated script in a Docker container, you can use the following Dockerfile as a reference.
+
+```
+FROM alpine:latest
+
+RUN apk add --update \
+    bash \
+    curl \
+    openssl \
+    && rm -rf /var/cache/apk/*
+
+WORKDIR dehydrated
+COPY . .
+
+ENTRYPOINT ["bash", "dehydrated"]
+```
+
+This builds a minimal Docker image (around 33mb) with all of the dependencies that dehyrdated needs to run and executes the script as an entrypoint.
+
+To build this, make sure you are in the root directory of the dehydrated project, then run the following command:
+
+```
+docker build -t dehydrated .
+```
+
+To run this, try the following command:
+
+```
+docker run -it --rm dehydrated
+```
+
+It should print out the default help message.  If you want to write the certs onto the host use a volume mount, like this:
+
+```
+docker run -it --rm -v $(pwd):/dehydrated dehydrated
+```
