+## Building and Running in Docker
+
+If you don't want to install `hugo` and its dependencies local machine, you can use
+docker to preview locally.  First checkout the `parquet-site` explained above 
+and then run:
+
+```shell
+# run docker container mounting the current directory to /parquet-site and exposing port 1313
+docker run -it -v `pwd`:/parquet-site -p 1313:1313  debian:bullseye-slim  bash
+
+# Install necessary utilities
+apt-get update
+apt-get install wget git -y xz-utils
+
+# Install extended version of hugo to /hugo
+# See releases https://github.com/gohugoio/hugo/releases/tag/v0.124.1
+# Note, if on amd64 use https://github.com/gohugoio/hugo/releases/download/v0.124.1/hugo_extended_0.124.1_linux-amd64.tar.gz
+wget -O - https://github.com/gohugoio/hugo/releases/download/v0.124.1/hugo_extended_0.124.1_linux-arm64.tar.gz  | tar xz
+
+# install golang to /go
