+BUILDING A GHIDRA JAR FILE
+--------------------------
+
+This file contains directions for building Ghidra into a single jar file and how to use that jar
+file to run Ghidra. 
+
+Normally, Ghidra is installed as an entire directory structure that allows
+modular inclusion or removal of feature sets and also provides many files that can be extended
+or configured. However, there are times when it would be useful to have all or some subset of
+Ghidra compressed into a single jar file at the expense of configuration options.  This makes Ghidra
+easier to run from the command line for headless operation or to use as a library of reverse 
+engineering capabilities for another Java application.
+
+Using the buildGhidraJar scripts, as described below, will build a minimal Ghidra 
+jar file that is suitable for running Ghidra or including in the class path for use with
+other Java applications (e.g., hadoop).  To have more control over which feature/extension modules
+are included in the ghidra.jar file, there is also a Ghidra script that you can customize and run
+from within Ghidra (BuildGhidraJarScript).
+
+Use of other non-Java scripting languages such as Python is not supported when running 
+from a single Ghidra jar configuration.
+
+To build the default ghidra.jar file run the appropriate buildGhidraJar script from the command
+line:
+
+Windows:
+	buildGhidraJar.bat [-srczip singleSrcZipFileName]
+
+Linux or Mac:
+	buildGhidraJar [-srczip singleSrcZipFileName]
+		
+The script creates a ghidra.jar file in the current directory. 
+
+If you specify the optional -srczip parameter, a single zip file containing all Ghidra source
+will be created that is useful for debugging.  Of course, you must have installed/unzipped the Ghidra
+source distribution into your install directory for the srczip option to work.
+
+
+To run Ghidra using the resulting ghidra.jar file, execute the following from the command line:
+
+GUI mode:
+
+	java -Xmx1024M -jar ghidra.jar -gui
+	
+Headless Analyzer:
+
+	java -Xmx1024M -jar ghidra.jar <headless-analyzer-args...>
+	
+To see full headless analyzer usage enter the following without any additional arguments:
+
+	java -Xmx1024M -jar ghidra.jar
+	
+*The above commands assume that a JDK 8 is installed on your system and is contained
+within your execution path.  
+
+**The -Xmx1024M specifies the amount of memory java is allowed to use. The 1024 sets the max
+Java VM memory to 1 gigabyte. 
+
+If you want to include more modules than the bare minimum, run Ghidra and then
+customize and run the BuildGhidraJarScript from within Ghidra.  The script has commented out
+example code indicating how to add additional modules.  If you want everything in your
+distribution, uncomment the "addAllModules()" call and then run the script.
