+## Change History
+__4.0.0:__
+* GhidraDev has been upgraded to be compatible with Ghidra 11.2 and later. It is not backwards
+  compatible with versions of Ghidra prior to 11.2. Older versions of GhidraDev will report an 
+  error when trying to link against Ghidra 11.2 or later.
+* GhidraDev now requires Eclipse 2023-12 4.30 or later.
+* GhidraDev now requires JDK 21.
+* Fixed an issue that could result in a `GhidraHelpService` exception when launching
+  Ghidra. GhidraDev now properly enforces that Ghidra is only launched with `Utility.jar` on the
+  initial classpath.
+  
+__3.1.0:__
+* GhidraDev has been upgraded to be compatible with Ghidra 11.1 and later. Older versions of
+  GhidraDev will report an error when trying to link against Ghidra 11.1 or later.
+* GhidraDev now supports importing a Ghidra module source directory. This will work best with Ghidra
+  module projects created from Ghidra 11.1 or later.
+* GhidraDev will now fail to launch Ghidra if a top-level `build` directory is detected. Presence of
+  this intermediate build artifact can cause Ghidra to have runtime/debugging issues.
+
+__3.0.2:__
+* GhidraDev no longer throws an IOException when performing a `Link Ghidra` action on a Ghidra 
+  project whose original Ghidra installation moved.
+* GhidraDev now prevents unsupported versions of PyDev from being used.
+
+__3.0.1:__
+* Exporting a Ghidra Module Extension produces an intermediate `build<` directory within the 
+  project. This `build` directory now gets automatically cleaned up to avoid Ghidra 
+  runtime/debugging issues.
+* GhidraDev now prevents unsupported Ghidra source repositories from being added as a Ghidra
+  installations.
+
+__3.0.0:__
+* GhidraDev now requires Eclipse 2021-12 4.22 or later.
+* GhidraDev now requires JDK 17.
+* Fixed an issue that could cause old extensions to incorrectly remain on the Ghidra project 
+  classpath after performing a `Link Ghidra`.
+
+__2.1.5:__
+* Eclipse Python breakpoints now work when Eclipse installs PyDev in .p2 bundle pool directory.
+
+__2.1.4:__
+* Fixed exception that occurred when performing a `Link Ghidra` on projects  that use a Gradle 
+  classpath container.
+
+__2.1.3:__
+* Fixed a bug that prevented Ghidra projects from recognizing extensions installed in the user's 
+  `~/.ghidra/.ghidra_<version>/Extensions` directory.
+
+__2.1.2:__
+* Fixed exception that occurred when creating a new Ghidra scripting project if a `~/ghidra_scripts`
+  directory does not exist.
+
+__2.1.1:__
+* Python debugging now works when PyDev is installed via the Eclipse `dropins` directory.
+* Fixed a bug in the check that prevents Ghidra projects from being created within the Ghidra 
+  installation directory.
+  
+__2.1.0:__
+* Added support for Ghidra 9.1.  GhidraDev 2.1.0 will be unable to create new Eclipse projects for
+  versions of Ghidra earlier than 9.1.
+* Prevented Ghidra projects from being created inside of a Ghidra installation directory.
+* Added an `Environments` tab to the Ghidra run configuration for setting environment variables
+  when launching Ghidra.
+
+__2.0.1:__
+* Fixed exception that occurred when performing certain actions on a Ghidra project that was 
+  imported from a previously exported Archive File.
+
+__2.0.0:__
+* Improved Ghidra module project starting templates for Analyzer and Plugin and added new templates
+  for Loader, Exporter, and FileSystem.
+* When creating a new Ghidra project, there is now an option to automatically create a Ghidra run
+  configuration for the project with a customizable amount of maximum Java heap space.
+* When creating a new Ghidra project, the project root directory now defaults to the workspace
+  directory if a project root directory has never been set.
+* When creating a new Ghidra project, the add button in the Python Support wizard page now
+  automatically adds the Jython interpreter found in the Ghidra installation directory to PyDev if
+  PyDev does have any Jython interpreters configured.
+* A Ghidra project's dependencies that are also projects are now passed along to a launched Ghidra
+  so Ghidra can discover those projects as potential modules.
+* The GhidraDev popup menu is now visible from within the Project Explorer (it was previously only
+  visible in the Package Explorer).
+* A new page has been added to the Export Ghidra Module Extension wizard that allows the user to 
+  point to a specific Gradle installation.
+
+__1.0.2:__
+* Fixed exception that occurred when performing a `Link Ghidra` on projects that specify other 
+  projects on their build paths.
+
+__1.0.1:__
+* Initial Release.
+
+## Minimum Requirements
+* Eclipse 2023-12 4.30 or later
+* Ghidra 11.2 or later
+
+## Optional Requirements
+* PyDev 6.3.1 - 9.3.0 ([more info](#pydev-support))
+* Gradle - required version(s) specified by linked Ghidra release 
+  ([more info](#export-ghidra-module-extension))
+
+## Installing
+GhidraDev can be installed either manually into Eclipse or automatically by Ghidra, depending on
+your uses cases. The following two sections outline both procedures.
+
+### Manual Installation in Eclipse
+GhidraDev can be installed into an existing installation of Eclipse the same way most Eclipse
+plugins are installed.  From Eclipse:
+1. Click `Help -> Install New Software...`
+2. Click `Add...`
+3. Click `Archive...`
+4. Select GhidraDev zip file from `<GhidraInstallDir>/Extensions/Eclipse/GhidraDev/`
+5. Click `OK` (name field can be blank)
+6. Check `Ghidra` category (or `GhidraDev` entry)
+7. Click `Next`
+8. Click `Next`
+9. Accept the terms of the license agreement
+10. Click `Finish`
+11. Check `Unsigned` table entry
+12. Click `Trust Selected`
+13. Click `Restart Now`
+
+### Automatic Installation through Ghidra
+Ghidra has the ability to launch an externally linked Eclipse when certain actions are performed,
+such as choosing to edit a Ghidra script by clicking the Eclipse icon in the Ghidra Script Manager.
+Ghidra requires knowledge of where Eclipse is installed before it can launch it, and will prompt the
+user to enter this information if it has not been defined.  Before Ghidra attempts to launch
+Eclipse, it will attempt to install GhidraDev into Eclipse's `dropins` directory if GhidraDev
+is not already installed.
+
+## GhidraDev Features
+GhidraDev provides a variety of features for creating and interacting with Ghidra-related
+projects in Eclipse.  GhidraDev supports creating both Ghidra script and Ghidra module projects.
+Ghidra scripts are typically designed as a single Java source file that is compiled by Ghidra at
+runtime and run through Ghidra's Script Manager or passed to the Headless Analyzer on the command
+line for execution.  Ghidra modules are intended to represent larger, more complex features such as
+Analyzers or Plugins.  When Ghidra modules are ready for production, they can be exported and
+installed into Ghidra as an "extension".
+
+#### New Ghidra Script
+Opens a wizard that creates a new Ghidra script with the provided metadata in the specified 
+location.  Ghidra scripts can be created in both Ghidra script and Ghidra module projects.
+
+#### New Ghidra Script Project
+Opens a wizard that creates a new Ghidra scripting project that is linked
+against a specified Ghidra installation.  The project can be set up to develop scripts in both the 
+user's home `ghidra_scripts` directory, as well as any scripts found in the Ghidra installation.
+
+#### New Ghidra Module Project
+Opens a wizard that creates a new Ghidra module project that is linked against a specified Ghidra
+installation.  The project can be initialized with optional template source files that provide a 
+good starting point for implementing advanced Ghidra features such as Analyzers, Plugins, Loaders, 
+etc.
+
+#### Import Ghidra Module Source
+Opens a wizard that imports a Ghidra module source directory as a new Ghidra module project.
+
+#### Export Ghidra Module Extension
+Opens a wizard that exports a Ghidra module project as a Ghidra extension to the project's `dist` 
+folder. The exported extension archive file can be distributed to other users and imported via 
+Ghidra's front-end GUI. The export process requires Gradle, which is configured in the wizard. Note
+that the Gradle version to use is specified in the linked Ghidra release's 
+`<GhidraInstallDir>/Ghidra/application.properties` file.
+
+#### Link Ghidra
+Links a Ghidra installation to an existing Java project, which enables Ghidra script/module
+development for the project. If a Ghidra installation is already linked to the project when this 
+operation is performed, the project will be relinked to the specified Ghidra installation, which can
+be used to build the project for a different version of Ghidra, discover new Ghidra extensions that
+were later added to a Ghidra installation, or repair a corrupted project.
+
+#### Preferences
+* __Ghidra Installations:__ Add or remove Ghidra installations. Certain features such as creating
+  Ghidra script/module projects require linking against a valid installation of Ghidra.
+* __Script Editor:__ The port used by Ghidra to open a script in Eclipse. Must match the
+  corresponding port in Ghidra's `Eclipse Integration` tool options. Disable this preference to 
+  prevent GhidraDev from listening on a port for this feature.
+* __Symbol Lookup:__ The project name and port used by Ghidra to perform symbol lookup in
+  Eclipse. Must match the corresponding port in Ghidra's `Eclipse Integration` tool options. Disable
+  this preference to prevent GhidraDev from listening on a port for this feature. Symbol lookup
+  requires the Eclipse CDT plugin to be installed 
+  (see [optional requirements](#optional-requirements) for supported versions).
+
+Most GhidraDev features can also be accessed by right-clicking on appropriate project elements in
+Eclipse's Project/Package Explorer. For example, the [Link Ghidra](#link-ghidra) feature can be 
+accessed by right-clicking on an existing Java project, and then clicking
+`Ghidra -> Link Ghidra...`.
+
+## Launching and Debugging Ghidra
+GhidraDev introduces two new run configurations to Eclipse which are capable of launching the
+installation of Ghidra that an Eclipse Ghidra project is linked to:
+* __Ghidra:__ Launches the Ghidra GUI.
+* __Ghidra Headless:__ Launches Ghidra in headless mode. By default, this run configuration will not
+  have any program arguments associated with it, which are required to tell headless Ghidra what 
+  project to open, what scripts to run, etc.  Newly created `Ghidra Headless` run configurations
+  will have to be modified with the desired headless program arguments. For more information on 
+  headless command line arguments, see `<GhidraInstallDir>/support/analyzeHeadlessREADME.html`.
+
+There are two ways to create Ghidra run configurations:
+1. Click `Run -> Run Configurations...`
+2. Right-click on `Ghidra` (or `Ghidra Headless`), and click `New`
+3. In the `Main` tab, click `Browse...` and select the Ghidra project to launch
+4. Optionally rename the new run configuration by editing the `Name` field at the top
+
+Alternatively, you can right-click on any Ghidra project in the Eclipse package explorer, and then
+click `Run As -> Ghidra`.
+
+To debug Ghidra, click `Debug As -> Ghidra`. GhidraDev will automatically switch Eclipse to the 
+debug perspective.
+
+__NOTE:__ Ghidra can only be launched/debugged from an existing Eclipse Ghidra project. Launching
+Ghidra from Eclipse independent of a project is not supported.
+
+## PyDev Support
+GhidraDev is able to integrate with PyDev to conveniently configure Python support into Ghidra
+script and module projects.
+
+### Installing PyDev
+From Eclipse:
+1. Download PyDev (see [optional requirements](#optional-requirements) for supported versions)
+2. Unzip PyDev
+3. Click `Help -> Install New Software...`
+4. Click `Add...`
+5. Click `Local...`
+6. Select unzipped PyDev directory
+7. Click `OK` (name field can be blank)
+8. Uncheck `Group items by category` (if applicable)
+9. Check `PyDev for Eclipse`
+10. Click `Next`
+11. Click `Next`
+12. Accept the terms of the license agreement
+13. Click `Finish`
+14. Click `Restart Now`
+
+### Configuring PyDev
+GhidraDev can add Python support to a Ghidra project when:
+* Creating a new Ghidra module project
+* Creating a new Ghidra script project
+* Linking a Ghidra installation to an existing Java project
+
+In order for GhidraDev to add in Python support, PyDev must have a Jython interpreter configured.
+GhidraDev will present a list of detected Jython interpreters that it found in PyDev's preferences.
+If no Jython interpreters were found, one can be added from GhidraDev by clicking the `+` icon.
+When the `+` icon is clicked, GhidraDev will attempt to find the Jython interpreter bundled with the
+selected Ghidra installation and automatically configure PyDev to use it.  If for some reason 
+GhidraDev was unable to find a Jython interpreter in the Ghidra installation, one will have to be 
+added manually in the PyDev preferences.
+
+## Upgrading
+GhidraDev is upgraded differently depending on how it was installed.  If GhidraDev was
+[manually installed in Eclipse](#manual-installation-in-eclipse), it can be upgraded the same was it
+was installed.
+
+If GhidraDev was [automatically installed through Ghidra](#automatic-installation-through-ghidra), 
+it can be upgraded by simply removing the GhidraDev file from Eclipse's `dropins` directory before
+following one of the two techniques described in the [Installing](#installing) section.
+
+## Uninstalling
+GhidraDev is uninstalled differently depending on how it was installed. If GhidraDev was
+[manually installed in Eclipse](#manual-installation-in-eclipse), it can be uninstalled as follows
+from Eclipse:
+1. Click `Help -> About Eclipse`
+    * For macOS: `Eclipse -> About Eclipse`
+2. Click `Installation Details`
+3. Select `GhidraDev`
+4. Click `Uninstall...`
+5. Select `GhidraDev`
+6. Click `Finish`
+7. Click `Restart Now`
+
+If GhidraDev was [automatically installed through Ghidra](#automatic-installation-through-ghidra), 
+it can be uninstalled by simply removing the GhidraDev file from Eclipse's `dropins` directory and
+restarting Eclipse.  The `dropins` directory can be found at the top level of Eclipse's
+installation directory.
+
+## Frequently Asked Questions
+* __I've created a Ghidra script project. Where should I create my new scripts?__
+    * The best place to create your scripts in is your home `~/ghidra_scripts` directory because 
+      Ghidra will automatically find them there without any additional configuration. By default,
+      your Ghidra script project will have a folder named `Home scripts` which is linked to your 
+      home `~/ghidra_scripts` directory. Either right-click on this folder in Eclipse and do 
+      `GhidraDev -> New -> GhidraScript...` or from the menu bar do `GhidraDev -> New -> 
+      GhidraScript...` and populate the `Script folder` box with your project's `Home scripts` 
+      folder.
+* __How do I launch Ghidra in headless mode from Eclipse?__
+    * GhidraDev provides custom run configurations to launch Ghidra installations both in GUI mode
+      and headlessly.  See the [Launching](#launching-and-debugging-ghidra) section for information
+      on how to launch Ghidra from Eclipse.
+* __Why doesn't my Ghidra module project know about the Ghidra extension I installed into my Ghidra
+  installation?__
+    * You most likely installed the Ghidra extension after the Ghidra installation was linked
+      to your Ghidra module project, which automatically happens when the project is created.
+      Simply [relink](#link-ghidra) your Ghidra installation to the project, and your project will 
+      pick up any newly discovered Ghidra extensions.
+* __Why doesn't GhidraDev support PyDev 10.0 or later?__
+    * PyDev dropped support for Python 2 in their 10.0 release. Ghidra currently does not support 
+      Python 3.
+

+please see the __Ghidra Scripting slide deck__
+at `<GhidraInstallDir>/docs/GhidraClass/Intermediate/Scripting.html`.
+
+## Building
+GhidraDev is currently built from Eclipse and distributed with Ghidra manually. Ideally we will use
+Gradle one day, but we aren't there yet. We do rely on `gradle prepDev` to generate the Eclipse 
+project and build GhidraDev's dependencies though.
+
+__NOTE:__ Only "Eclipse for RCP and RAP Developers" has the ability to do the below instructions. 
+The following instructions assume that you are using this version of Eclipse.
+
+#### Importing GhidraDev Eclipse projects (they are deactivated by default):
+1. Run `gradle eclipse -PeclipsePDE`
+2. From Eclipse, `File -> Import -> General -> Existing Projects into Workspace`
+3. From the ghidra repo, import `Eclipse GhidraDevFeature` and `Eclipse GhidraDevPlugin`
+
+#### Changing version number (GhidraDev is versioned independently of Ghidra):
+1. Open `plugin.xml` in the GhidraDevPlugin project
+2. In the `Overview` tab, update the `Version` field to `x.y.z.qualifier` and save
+3. Open `feature.xml`in the `GhidraDevFeature` project
+4. In the `Overview` tab, update the `Version` field to `x.y.z.qualifier` and save
+5. Open `category.xml` in the `GhidraDevFeature` project
+6. Highlight `ghidra.ghidradev (x.y.z.qualifier)`, and click `Remove`
+7. Highlight `ghidra.ghidradev` and click `Add Feature`
+8. Select `ghidra.ghidradev (x.y.z.qualifer)`, click `OK`, and save
+9. Update the [Change History](#change-history) section if necessary
+
+#### Building from Eclipse:
+1. Do a `gradle prepDev` to ensure GhidraDev's dependencies are up-to-date
+2. `File -> Export -> Plug-in Development -> Deployable features`
+3. Check `ghidra.ghidradev (x.y.z.qualifier)`
+4. Select `Archive file` and choose a directory to save it to. Name it `GhidraDev-x.y.z.zip`.
+5. In the `Options` tab make sure things look like this:
+    * Export source: UNCHECKED
+    * Package as individual JAR archives: CHECKED
+    * Generate p2 repository: CHECKED
+    * Categorize repository: CHECKED + Browse to category.xml file in the GhidraDevFeature project
+    * Qualifier replacement: CHECKED + clear field so default is used
+    * Save as Ant script: UNCHECKED
+    * Allow for binary cycles in target platform: CHECKED
+    * Use class files compiled in the workspace: UNCHECKED
+6. Finish
