 The loader will fallback to the default PowerPC processor if the Gekko/Broadway language is not found, but do not expect good results if the program uses any paired single instructions.
 
-# Usage
+## Building
+- Ensure you have ``JAVA_HOME`` set to the path of your JDK 17 installation.
+- Set ``GHIDRA_INSTALL_DIR`` to your Ghidra install directory. This can be done in one of the following ways:
+    - **Windows**: Running ``set GHIDRA_INSTALL_DIR=<Absolute path to Ghidra without quotations>``
+    - **macos/Linux**: Running ``export GHIDRA_INSTALL_DIR=<Absolute path to Ghidra>``
+    - Using ``-PGHIDRA_INSTALL_DIR=<Absolute path to Ghidra>`` when running ``./gradlew``
+    - Adding ``GHIDRA_INSTALL_DIR`` to your Windows environment variables.
+- Run ``./gradlew``
+- You'll find the output zip file inside `/dist`
 
-Install the extension using the `Install Extensions` option inside Ghidra.
+## Installation
+- Copy the zip file to ``<Ghidra install directory>/Extensions/Ghidra``.
+- Start Ghidra and use the "Install Extensions" dialog to finish the installation. (``File -> Install Extensions...``).
 
-Once the extension is installed, you can import a .rpx/.rpl file via `File->Import File...`.
+## Usage 
-
+- Choose the `Gekko/Broadway/Espresso` language if asked
-# Building
-
-```
-cd /path/to/extension
-export GHIDRA_INSTALL_DIR=/path/to/ghidra 
-gradle 
-```
-
-Output goes into `dist`
 
 # Eclipse
 
-To be able open this module in eclipse, you need to create a new Ghidra Module and copy the `.classpath`, `.project` and `.settings` to copy of this repository.

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
