+### Collector Exporter
+You can use the [opentelemetry-collector][opentelemetry-collector-url] docker container.
+For that please make sure you have [docker](https://docs.docker.com/) installed
+ - Run the docker container
+   ```sh
+   $ # from this directory
+   $ # open telemetry
+   $ npm run collector:docker:ot
+   $ # at any time you can stop it
+   $ npm run collector:docker:stop
+   ```
+
+#### Collector Exporter - Zipkin UI
+The [opentelemetry-collector][opentelemetry-collector-url] 
+docker container is using [Zipkin Exporter](#zipkin).
+You can define more exporters without changing the instrumented code.
+To use default [Zipkin Exporter](#zipkin) please follow the section [Zipkin UI](#zipkin-ui) only
+
 ### Export to multiple exporters
