+
+## Installing XEphem
+
+There are XEphem packages available for several operating systems:
 
 * [Gentoo](https://packages.gentoo.org/packages/sci-astronomy/xephem)
 * [openSUSE](https://build.opensuse.org/package/show/Application:Geo/xephem)
 * [Slack](https://slackbuilds.org/repository/13.37/academic/xephem/)
 
-If none of these packages is appropriate for your system,
-the [INSTALL file](https://github.com/XEphem/XEphem/blob/main/INSTALL)
-explains how you can compile XEphem yourself from its source code.
+Or you can try compiling from source code.  XEphem should compile fine
+on modern Linux systems, though perhaps not as well for folks on macOS.
+The source includes an `INSTALL` file with instructions.  There are two
+ways to get the source:
 
-# Documentation
+* Download a recent [release](https://github.com/XEphem/XEphem/releases)
+* Checkout the [git repository](https://github.com/XEphem/XEphem)
 
-* [Home Page](https://xephem.github.io/XEphem/Site/xephem.html)
+If you want to get it running quickly from the source code, the
+repository includes the code for three Docker containers that are each
+capable of compiling and running XEphem.  The commands to launch them
+when sitting at the repository root are:
 
-* [Reference Manual](https://xephem.github.io/XEphem/GUI/xephem/help/xephem.html)
+    $ ./Containers/docker-ubuntu-14.04/run
+    $ ./Containers/docker-ubuntu-20.04/run
+    $ ./Containers/docker-ubuntu-21.04/run
 
-* [Changelog](https://xephem.github.io/XEphem/Site/changes.html)
+Once one of the containers has launched, use the shell command history:
+press up-arrow to ask for the previous command — it will be the correct
+command to compile and run XEphem.
 
-# Project Status
+The repository also includes a `.tito` directory and `xephem.spec` file
+for building an XEphem RPM package.
 
-* Elwood Downey has generously released XEphem under the MIT License!
-  An “XEphem” organization has been created on GitHub
-  to host XEphem’s [source code](https://github.com/XEphem/XEphem).
-
-* The XEphem community hopes to modernize the code
-  to make it easier to compile, package, and run on modern systems.
-  In the meantime,
-  XEphem compiles most readily on older Linux platforms
-  like Ubuntu 14.04.
-
-* If you want to get started immediately,
-  a Docker image
-  that successfully compiles and runs XEphem atop Ubuntu 14.04
-  is available.
-  It’s documented
-  [in its own README file](https://github.com/XEphem/XEphem/blob/main/container/README.md).
-
-* The repository also includes a `.tito` directory
-  and `xephem.spec` file for building an XEphem RPM package.
-
-* Otherwise,
-  if you want to tackle XEphem development on another platform,
-  start with the
-  [INSTALL](https://github.com/XEphem/XEphem/blob/main/INSTALL)
-  file in the `main` branch of the repository.
-
-* Direct questions to the main repository’s
-  [GitHub Discussions](https://github.com/XEphem/XEphem/discussions)
-  by clicking “New discussion” and writing up your question.
