 You should have a [PyPi](https://pypi.org/) account and be added as an owner/maintainer on the [etherpump package](https://pypi.org/project/etherpump/).

+
+It can be quite handy to run a very temporary local Etherpad instance to test against. This is possible with [Docker](https://docs.docker.com/get-docker/).
+
+```bash
+$ docker run -d --name etherpad -p 9001:9001 etherpad/etherpad
+$ docker exec -ti etherpad cat APIKEY.txt;echo
+```
+
+Then you can `etherpump init` to that local Etherpad for experimentation and testing. You use `http://localhost:9001` as the pad URL.
+
+Later on, you can remove the Etherpad with:
+
+```bash
+$ docker rm -f --volumes etherpad
+```
