+# Dockerfile for pandas development
+#
+# Usage:
+# -------
+#
+# To make a local build of the container, from the 'Docker-dev' directory:
+# docker build  --rm -f "Dockerfile" -t <build-tag> "."
+#
+# To use the container use the following command. It assumes that you are in
+# the root folder of the pandas git repository, making it available as
+# /home/pandas in the container. Whatever changes you make to that directory
+# are visible in the host and container.
+# The docker image is retrieved from the pandas dockerhub repository
+#
+# docker run --rm -it -v $(pwd):/home/pandas pandas/pandas-dev:<image-tag>
+#
+# By default the container will activate the conda environment pandas-dev
+# which contains all the dependencies needed for pandas development
+#
+# To build and install pandas run:
+#               python setup.py build_ext -j 4
+#               python -m pip install -e . --no-build-isolation
+#
+# This image is based on: Ubuntu 20.04 (focal)
+# https://hub.docker.com/_/ubuntu/?tab=tags&name=focal
