 Installation
 ------------
 PdfJumbler requires a Java Runtime Environment (JRE).
-You can download one at <http://www.java.com>.
-(Linux users should use their package management
-system and install, for example, the packages
-`default-jre` and `libopenjfx-java`,
-MacOS usually comes with a preinstalled JRE).
+You can download one at <http://www.java.com> or <https://adoptopenjdk.net/>.
 
-Windows users can simply download and run the
-installer (setup-pdfjumbler.exe), which
-creates a start menu entry for PdfJumbler.
+Windows users can simply download and run the installer (setup-pdfjumbler.exe),

-Alternatively, there is a runnable jar file (just
-doubleclick), pdfjumbler.jar.
-
-
-Plugins
--------
-Both the installer and the runnable jar include
-the iText editor and the JPedal renderer.
-
-In the rare case that these standard plugins can't
-handle a particular file, other plugins can be
-installed simply by putting the respective jar files
-in the installation directory (often something like
-`C:\users\<user>\Local Settings\Application Data\
-PdfJumbler`, or wherever you put the main jar file --
-when in doubt search for files named `pdfjumbler-*.jar`).
+Alternatively, there is a runnable jar file (just double-click), pdfjumbler.jar.
