+
+Node.js library to interact with the StApps backend service
+
+## Use this as a standalone program
+To get some data into a local `backend-node`-instance, you can run this 
+as a standalone program to copy data of a remote `backend-node`-instance
+into your local one.
+
+Example to copy all Events of the b-tu instance: 
+```shell
+npm install
+npm run build
+node ./lib/cli.js copy -t Event --appVersion 1.0.0 https://stappsbe01.innocampus.tu-berlin.de http://localhost:3000
+```
+
+### Program arguments:
+
+```shell
+node ./lib/cli.js copy --appVersion <app version> -t <vc type> <source> <target>
+```
+
+Example execution with docker when backend is running on `localhost:3000`:
+
+```shell
+docker run --net=host registry.gitlab.com/openstapps/api/copy copy -t Place --appVersion 1.0.0 https://stappsbe01.innocampus.tu-berlin.de http://localhost:3000
+```
