 CALENDAR IMPORTER AND EXPORTER:
 ===
 
-## Building the calendar importer plugin from source:
+Building the calendar importer plugin for Zarafa WebApp:
 
-### Dependencies
- - Kopano WebApp Source Code (https://stash.kopano.io/projects/KW/repos/kopano-webapp/browse)
- - PHP >= 5 (7 or higher recommended)
- - composer (https://getcomposer.org/)
- - JDK 1.8 (http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html)
- - ant (http://ant.apache.org/)
-
-Add JAVA_HOME (e.g. C:\Program Files\Java\jdk1.8.0_161) to your path. Also add Ant, Composer, PHP and Java to the global PATH variable!
-
-### Compiling the plugin
-Unzip (or use git clone) the sourcecode of Kopano WebApp to a new directory. In this README we call the source folder of WebApp "kopano-webapp-source".
-
-Then generate the WebApp build utils:
 ```
-cd kopano-webapp-source
+cd /zarafa/webapp/
 ant tools
-```
-
-Next clone the plugin to the WebApp plugin directory:
-```
-cd kopano-webapp-source\plugins
+cd /zarafa/webapp/plugins/
 git clone https://git.sprinternet.at/zarafa_webapp/calendarimporter.git
-```
-
-Now lets build the plugin:
-```
-cd kopano-webapp-source\plugins\calendarimporter\php
-composer install
-cd kopano-webapp-source\plugins\calendarimporter
+cd calendarimporter
 ant deploy
 ```
 
-The compiled plugin is saved to `kopano-webapp-source\deploy\plugins\calendarimporter`.
+### Usage
+Rightclick a calendarfolder or calendar entry to export it as iCal.
 
-## Installing the plugin
+Rightclick a calendarfolder to import a iCal file.
 
-### From compiled source
-Copy the whole folder "calendarimporter" to your production WebApp (`kopano-webapp-production\plugins\calendarimporter`)
-
-For example:
-```
-cp -r kopano-webapp-source\deploy\plugins\calendarimporter kopano-webapp-production\plugins\
-```
-
-## Installing the sync backend
-
-### From source
-Copy the whole folder "kopano-webapp-source\plugins\calendarimporter\backend" to a destination of cour choice.
-
-For example:
-```
-cp -r kopano-webapp-source\plugins\calendarimporter\backend /opt/ical-sync/backend
-```
-
-### From precompiled download
-Download the newest backend release from https://git.sprinternet.at/zarafa_webapp/calendarimporter/tree/master/DIST.
-
-Unzip the downloaded file and copy the backend folder to a destination of cour choice.
-
-For example:
-```
-cp -r Downloads\calendarimporter_backend /opt/ical-sync/backend
-```
-
-## WebApp Plugin Configuration
-Edit the config.php file in the plugin root path to fit your needs.
-
-Available configuration values:
-
-| Configuration Value        | Type           | Default  | Desctription |
-| ------------- |:-------------:| ----- | ----- |
-| PLUGIN_CALENDARIMPORTER_USER_DEFAULT_ENABLE     | boolean | false | Set to true to enable the plugin for all users |
-| PLUGIN_CALENDARIMPORTER_USER_DEFAULT_ENABLE_SYNC     | string | true | Set to true to enable the sync feature for all users |
-| PLUGIN_CALENDARIMPORTER_DEFAULT     | string | "Kalender" | Default calendar folder name (might be "Calendar" on english installations) |
-| PLUGIN_CALENDARIMPORTER_DEFAULT_TIMEZONE     | string | "Europe/Vienna" | The local Timezone |
-| PLUGIN_CALENDARIMPORTER_TMP_UPLOAD     | string | "/var/lib/kopano-webapp/tmp/" | Temporary path to store uploaded iCal files |
-
-## Sync Backend Configuration
-First you have to create a new Kopano user with admin rights.
-For example:
-```
-kopano-admin -c adminuser -e admin@domain.com -f "Calendar Sync Admin" -p topsecretpw -a 1
-```
-Then edit the config.php file of the sync backend to fit your needs.
-
-Available configuration values:
-
-| Configuration Value        | Type           | Default  | Desctription |
-| ------------- |:-------------:| ----- | ----- |
-| $ADMINUSERNAME     | string | "adminuser" | The newly created Kopano admin user |
-| $ADMINPASSWORD     | string | "topsecretpw" | The password of the admin user |
-| $SERVER     | string | "http://localhost:236/kopano" | Kopano Socket or HTTP(S) connection string |
-| $CALDAVURL     | string | "http://localhost:8080/ical/" | Kopano CalDAV URL |
-| $TEMPDIR     | string | "/tmp/" | Temporary path to store synchronised iCal files (must be writeable by the user executing the sync script) |
-
-Next set up a cronjob to allow periodic syncing of ical items.
-
-For example: (`/etc/crontab`):
-```
-# sync ics calendars every minute (interval can be changed by the user)
-* * * * * icssync /opt/ical-sync/backend/sync.php > /var/log/icssync.log 2>&1
-```
-
-If you get an error, make sure that the mapi module is loaded for php-cli. Therefore create or modify: `/etc/php7/cli/conf.d/50-mapi.ini`
-``` 
-extension=mapi.so 
-```
-
-Do no run the sync script as root! Create a user without admin rights (`adduser icssync`), and change permissions of the tmp folder accordingly.
-
-## Usage
-
-The plugin add context menu entries to calendar folders.
-
-![Plugin Context Menus](https://git.sprinternet.at/zarafa_webapp/calendarimporter/raw/master/usage.png "Kopano Webapp Context Menu")
-
-If syncing is enabled, the calendar section in the WebApp settings gets extended with a synchronisation overview. There you can add new iCal URLs for syncing.
-
-![Plugin Settings Menus](https://git.sprinternet.at/zarafa_webapp/calendarimporter/raw/master/usage_sync.png "Kopano Webapp Settings Menu")
+Rightclick a iCal attachment to import it.
