Any hardware and operating system that offers Java 5 and up, so it works on old machines and new machines.

1. Mount .dmg file.
2. Copy Rune.app to Application folder.
3. Double-click Rune.app

I am still working on the installer.

1. Make sure Java is installed. Any version 5 and above will work.
	a. For Intel/AMD you can get it from https://java.sun.com
	b. For ARM you can get it from https://www.microsoft.com/openjdk
2. Run this from the command line: java -jar rune.jar

1. Install a version of openjdk greater than or equal to 5.
2. Run this from the command line: java -jar rune.jar

1. Install Java 6 from https://trac.netlabs.org/java
2. Add the Java bin directory to your PATH
3. You may need to restart
4. Run this from the command line: java -jar rune.jar

Not everything works right. For example, only one file can be opened. I'm not sure it this is caused by bugs in the Haiku Java port, or bugs in Rune that can't be seen on other platforms. I will try to look into it when I have time. There are also issues with memory that require some extra parameters on the Java command line. So it is necessary to create a script to start up Rune.

1. Install any available version of openjdk from HaikuDepot.
2. Add the Java install directory to your PATH. It will be
   something like /system/lib/openjdk/bin
3. You may need to restart
4. Run this from the command line: java -jar rune.jar
