+# CityDoctor2 Extensions
+Extension modules to the core functionality of CityDoctor2.
+
+# Loading
+
+Except for CityDoctorGUI, all extension modules are not loaded into the Maven project by default.
+If you wish to load an extension, you can either import the respective Maven module directly, or adjust the CityDoctorParent
+pom.xml and move the respective modules out of the comment-block in the module list found at the end of the file.
+
+# Building
+
+All loaded modules will also be built upon building of the CityDoctorParent.
+
+# Module Information
+
+## CityDoctorAutoPro
+
+
+
+The AutoPro (short for automated processing) module is an interface for the conversion of the internal data model to a C++
+representation, to allow use of advanced functionalities of CGAL with CityDoctor2.
+
+### Usage
+
+The AutoPro module is deprecated and will be removed in a future release, once the C++ functionalities have been ported to Java.
+
+AutoPro requires a collection of .dll files to run, some of which are not available as open source projects. Access to the collection is only granted upon request. Contact a Maintainer for further information.
+
+## CityDoctorGUI
+
+
+The GUI module offers a graphical user interface for CityDoctor2, including a model viewer allowing for visual
+inspection of validation results and found errors.
+
+### View Plugins
+
+The GUI is expandable via plugins, enabling the creation of views for custom functionalities or extensions of the CityDoctor2 core.
+Custom views can be created by extending the Abstract class `View` of the CityDoctorGUI and need to be registered by calling
+`ViewRegistration.registerView(View view);` before starting the GUI.
+
+### Usage
+
+> âš CityDoctorGUI requires a JDK/JRE containing the JavaFX library to run.
+
+Prebuilt binaries for the GUI are available in [CityDoctorReleases](https://transfer.hft-stuttgart.de/gitlab/citydoctor/citydoctorreleases).
+After extracting the archive the GUI can be started with **start.bat**.
+
+Binaries can be built with Maven using the create-binaries profile from the CityDoctorParent directory:
+```
+mvn install -P create-binaries
+```
+
+Lastly, the GUI can also be started by calling `MainWindow.main(args[])`.
+
+
+## CityDoctorHealer
+
+
+CityDoctorHealer implements functionalities for the automated repair of geometries containing errors.
+The healer uses naive approaches to fix geometrical errors, and thus, it cannot be guaranteed that semantical
+correctness is maintained after the healing process.
+
+
+### Usage
+
+Usage of CityDoctorHealer is similar to [CityDoctor](https://transfer.hft-stuttgart.de/gitlab/citydoctor/citydoctor2/-/tree/dev_GUI#usage).
+An example start command looks like this:
+```
+java -classpath libs/*;plugins/*;CityDoctorHealer-<version>.jar de.hft.stuttgart.citydoctor2.CityDoctorHealer -in <path-to-gml-file>.gml -config <path-to-validation-config>.yml -xmlReport <path-to-xml-output>.xml -pdfReport <path-to-pdf-output>.pdf -out <path-to-output-gml>.gml
+```
+Note: Unlike the CityDoctor core, the _-out_ argument is required
+
+To prevent infinite loops the `Healer` class has a limit for the number of healing iterations (default: 200). This limit
+can be changed by calling `Healer.setNumberOfIterations(int limit)`.
+
+## CityDoctorHealerGenetic
+
+
+CityDoctorHealerGenetic uses a genetical algorithm to establish an optimal CityDoctorHealer healing-plan for geometries containing errors.
+
+### Usage
+> âš This module has been abandoned. As of writing the module is still functional, but it may break at any time.
+>Issues, bug reports and suggestions for this module will not be processed. Use at your own discretion.
+
+Usage is nearly identical to CityDoctorHealer, only requiring changing the classpath to the HealerGenetic jar.
+
+A View for usage with CityDoctorGUI is included.
+
+## CityDoctorHealerGUI
+
+
+CityDoctorGUI-view for CityDoctorHealer.
+
+### Usage
+
+See [CityDoctorGUI](#view-plugins)
+
+
+## CityDoctorWebService
+
+
+Web service API for CityDoctor.
+
+### Usage
+> âš This module has been abandoned. As of writing the module is still functional, but it may break at any time.
+>Issues, bug reports and suggestions for this module will not be processed. Use at your own discretion.
+
+Run on a Tomcat Server.
+
+
+# Build
+
+Use [Maven](https://maven.apache.org/) to build CityDoctor2.
+
+```bash
+cd CityDoctorParent
+mvn install
+```
