-## Setup
+![Kalamar-Plugin-Export Screenshot](https://raw.githubusercontent.com/KorAP/Kalamar-Plugin-Export/misc/kalamar-export-screenshot.png)
 
-The jar file is located in the ```target/``` folder
+## Description
 
-## Customizing KalamarExportPlugin configuration
+Kalamar-Plugin-Export is a web service that integrates in the plugin framework of
+[Kalamar](https://github.com/KorAP/Kalamar), to export matches for the
+[KorAP Corpus Analysis Platform](http://korap.ids-mannheim.de/) in various formats.
 
-Copy the default  configuration file ```plugin/src/main/resources/exportPlugin.conf``` to the same  folder as the KalamarExportPlugin jar file  (```/target```). Please do not change the name of the configuration file.
+Currently supported are **RTF**, **CSV**, and **JSON**.
+
+Kalamar-Plugin-Export is meant to be a basic export plugin and should
+demonstrate and evaluate the plugin capabilities of Kalamar.
+
+
+## Prerequisites
+
+Java 8 (OpenJDK or Oracle JDK),
+[Git](http://git-scm.com/),
+[Maven 3](https://maven.apache.org/).
+Further dependencies are resolved using Maven.
+
+
+## Build
+
+To build the latest version of Kalamar-Plugin-Export, do ...
+
+```shell
+$ git clone https://github.com/KorAP/Kalamar-Plugin-Export
+$ cd Kalamar-Plugin-Export
+```
+
+... and build the jar file ...
+
+
+```shell
+$ mvn clean package
+```
+
+Afterwards the jar file is located in the `target/` folder and can
+be started with ...
+
+```shell
+$ java -jar KalamarExportPlugin-[VERSION].jar
+```
+
+Per default, this will start a server at `http://localhost:7777`.
+It will also create a subfolder `files` to temporarily store created
+exports.
+
+Registration of the plugin in Kalamar is not yet officially supported.
+Registration works by passing the following JSON blob
+to the plugin registration handler.
+
+```json
+{
+  "name" : "Export",
+  "desc" : "Exports Kalamar results",
+  "embed" : [{
+    "panel" : "result",
+    "title" : "exports KWICs and snippets",
+    "icon" : "\uf019",
+    "classes" : ["button-icon", "plugin" ],
+    "onClick" : {
+      "action" : "addWidget",
+      "template" : "http://localhost:7777/export"
+    }
+  }]
+}
+```
+
+An [example demo](https://github.com/KorAP/Kalamar/blob/master/dev/demo/export.html)
+showcases the embedded plugin.
+
+
+## Customization
+
+The default configuration file is stored in `src/main/resources/exportPlugin.conf`.
+This file can be overwritten, when a file of that name is stored in the
+same directory as the jar file.
