+# This Docker image encapsulates the REMnux v7 distro on Ubuntu 20.04 (focal).
+# For details about REMnux, including how you can run it on a physical system
+# or as a virtual machine, see https://REMnux.org.
+#
+# You can run this image as a container using a command such as:
+#
+# docker run --rm -it remnux/remnux-distro /bin/bash
+#
+# To map a local directory into the container's /home/remnux/files directory,
+# you could use a command lile this by supplying the appropriate directory name:
+#
+# docker run --rm -it -v <local_directory>:/home/remnux/files remnux/remnux-distro /bin/bash
+#
+# If you'd like to access the container using SSH,  you can invoke it like this by
+# mapping your local TCP port 22 to the container's internal TCP port 22. In this example,
+# the container will remain active in the background:
+#
+# docker run -d -p 22:22 remnux/remnux-distro
+#
+# If you're going to run this container in a remote cloud, be sure to change the default
+# password and otherwise harden the system according to your requirements.
+#
+# If you're planning to use Cutter inside the container, you'll need to include the
+# --privileged parameter when invoking Docker.
