 # Run-REDUCE Install and Run Guide
 
-## Francis Wright, December 2020
-
 Run-REDUCE is an open-source JavaFX GUI to run the REDUCE Computer
 Algebra System.  REDUCE must be obtained from
 [SourceForge](https://sourceforge.net/projects/reduce-algebra/) and
 installed separately.  Run-REDUCE should find a standard REDUCE
 installation automatically and not **require** any initial
-configuration, at least on Microsoft Windows and Linux.  With
+configuration, at least on Microsoft Windows and Gnu/Linux.  With

+it **should** run on any platform that supports JavaFX, but I can only
+test on 64-bit Windows, Ubuntu and Fedora.
+
+I recommend that you use the appropriate installer but you can also
+use the platform-independent JAR, although this is considerably more
+complicated.  Please note that: the installers are quite large, around
+50 MB, whereas the JAR is well under 1 MB; I may release installers
+less frequently than JARs.
+
+
+## Using an Installer
+
+I provide installers for 64-bit Windows and Gnu/Linux, which include
+customised versions of Java and JavaFX (but not REDUCE).  The
+appropriate installer will have a name of the following form, where
+*\<version\>* represents the version of Run-REDUCE:
+
+Platform                             | Installer Filename
+-------------------------------------|-------------------
+Microsoft Windows                    | Run-REDUCE-*\<version\>*.msi
+Debian-based Gnu/Linux, e.g. Ubuntu  | run-reduce\_*\<version\>*-1_amd64.deb
+Red Hat-based Gnu/Linux, e.g. Fedora | run-reduce-*\<version\>*-1.x86\_64.rpm
+
+Download the latest available installer file for your platform from
+the [GitHub releases
+page](https://github.com/fjwright/Run-REDUCE/releases) and run it,
+e.g. by double-clicking on it.
+
+### Microsoft Windows
+
+The Run-REDUCE package will be installed in the folder `C:\Program
+Files\Run-REDUCE` by default, but you can change this.  It will appear
+as an installed app in *Settings* under *Apps & features*, which can
+be used to uninstall it.  It will also appear in the *Start Menu* in
+the *Reduce* folder, which provides the recommended way to run it.  To
+update the Run-REDUCE package you just need to run the installer for
+the new version.
+
+### Gnu/Linux
 
-You need to have a Java Runtime Environment (JRE) and JavaFX libraries
-installed, both version 11 or later (preferably the latest release);
-see below for details.
+The Run-REDUCE package will be installed in the directory
+`/opt/run-reduce` and will appear as an installed app in *Software*,
+which can be used to uninstall it.  It will also appear in
+*Applications* in the *Unknown/Other* category, which provides the
+easiest way to run it.
+
+To update the Run-REDUCE package you need to uninstall the old version
+and then install the new version.  One way to do this is to run the
+installer for the new version **twice**; the first run just invites
+you to uninstall the old version, but does not install the new
+version.
+
+The executable is actually installed as
+`/opt/run-reduce/bin/Run-REDUCE` and you can use this full pathname as
+a shell command to run Run-REDUCE if you want, but the directory is
+not automatically added to your PATH.  Note that if you run Run-REDUCE
+this way then you will probably see a GDK warning message, which you
+can ignore.  (It is not displayed when you run Run-REDUCE from
+*Applications*.)
+
+
+## Using the JAR
+
+To run the JAR, you need to have a Java Runtime Environment (JRE) and
+JavaFX libraries installed, both version 11 or later (preferably the
+latest release); see below for details.
