+Requirements
+------------
+
+All you need is Docker (
+https://docs.docker.com/install/#supported-platforms ) or podman (
+https://podman.io/getting-started/installation ) and some means of
+running bash scripts.  This means you can run this on a MacOS box,
+even though it's very much a Linux build process.  Windows should
+also be possible, albeit with some difficulty (because you have to
+get bash).
+
+You really need at least 2GiB of free RAM; Prince will swap like
+crazy otherwise.
+
+The builds will run in a podman (preferred) or docker container,
+depending on what you have available.
+
+Usage
+-----
+
 To make all the versions do:
 
   ./run_container.sh
 
+Note that this takes a while, proportionate to available CPU; on an
+AWS t2.micro I gave up after over 2 hours due to it running out of
+RAM.  On an AWS t2.medium it took about an hour.  RAM is a
+significant consideration; it needs at least 2GiB free (and possibly
+more).
+
 The final results will end up under the build/ directory, scattered
 about in various places.  If you would like the final outputs only
 to be copied to another directory, i.e. for web display, you can use
