+
+## What is `Zipcall`
+
+
+Documents: [Zipcall](https://github.com/ianramzy/decentralized-video-chat)
+
+Demo: [Zipcall](https://zipcall.io)
+
+## How to setup
+
+1. Sign up for free twilio account https://www.twilio.com/login
+2. Get your Account SID and Auth Token from the Twillio console
+3. Create a docker service using the following command
+4. View http://localhost:3000 to see your running video chat service
+
+```
+docker service create \
+	--name zipcall \
+	--replicas 1 \
+	--publish 3000:3000 \
+	--env TWILIO_ACCOUNT_SID="SID" \
+	--env LOCAL_AUTH_TOKEN="Token" \
+	--mount type=bind,src=/etc/localtime,dst=/etc/localtime,readonly \
+	newnius/zipcall
+```
+
+## Notice
+
+_This command creates a docker swarm service, you can use `docker run ...` instead in your way_
