+## Deployment instructions
+
+The deployment of OpenVidu on Digital Ocean is within your grasp using these instructions. 
+
+### 1.  Create Droplet
+Create a new DO droplet based on the [docker marketplace image](https://marketplace.digitalocean.com/apps/docker).
+
+The standard droplet is sufficient for testing and limited production use.
+### 2.  Update docker-compose
+SSH in as root and perform the following:
+
+    rm /usr/local/bin/docker-compose
+    VERSION="$(curl --silent https://api.github.com/repos/docker/compose/releases/latest | jq .name -r)"
+    DESTINATION=/usr/local/bin/docker-compose
+    sudo curl -L https://github.com/docker/compose/releases/download/${VERSION}/docker-compose-$(uname -s)-$(uname -m) -o $DESTINATION
+    sudo chmod 755 $DESTINATION
+
+### 3. Download and install newest copy of OpenVidu
+    cd /opt/
+    curl https://s3-eu-west-1.amazonaws.com/aws.openvidu.io/install_openvidu_latest.sh | bash
+
+### 4. Configure OpenVidu
+You can manually edit the `/opt/openvidu/.env` file. However, if you want to work completely from the prompt or incorporate the setup into a script use the following steps:
+
+####Development OpenVidu Configuration
+If you are building an OpenVidu instance for your own testing you don't need a domain. 
+
+You'll access it by the IP address, and browsers will complain about the self-signed certificate.
+
+Set the following environment variables:
+
+```
+IPADDRESS=[your Droplet IP Address]
+OVSECRET=[a self-chosen string to act as your secret]
+```
+Add them to OpenVidu's .env:    
+```
+sed -i "s/DOMAIN_OR_PUBLIC_IP=/DOMAIN_OR_PUBLIC_IP=$IPADDRESS/g" /opt/openvidu/.env
+sed -i "s/OPENVIDU_SECRET=/OPENVIDU_SECRET=$OVSECRET/g" /opt/openvidu/.env
+```
+####Production OpenVidu Configuration
+If you want to access droplet using a proper domain name and have browsers be happy, there are a few more steps.
+
+First point your chosen domain at the droplet's IP address. 
+
+If you're using Digital Ocean as your DNS, you can do this by creating an A record in Networking 
+and then pointing it at the IP address for your new droplet. Otherwise, do this at your registrar. 
+
+> **Note**: OpenVidu will not be able to complete the letsencrypt certbot process if the domain is not resolving on the IP address.  Be sure you have given ample time for the domain name you've assigned to propagate. 
+
+Configure OpenVidu's .env file first by setting the following environment files:
+
+    DOMAINNAME=[your domain name, i.e. ov.mydomain.com]
+    OVSECRET=[a self-chosen string to act as your secret]
+    ADMINEMAIL=[a valid email you wish to attach to the SSL certificate]
+Then add them to OpenVidu's configuration using the following:    
+
+    sed -i "s/DOMAIN_OR_PUBLIC_IP=/DOMAIN_OR_PUBLIC_IP=$DOMAINNAME/g" /opt/openvidu/.env
+    sed -i "s/OPENVIDU_SECRET=/OPENVIDU_SECRET=$OVSECRET/g" /opt/openvidu/.env
+    sed -i "s/[email protected]/LETSENCRYPT_EMAIL=$ADMINEMAIL/g" .env
+    sed -i "s/CERTIFICATE_TYPE=selfsigned/CERTIFICATE_TYPE=letsencrypt/g" .env
+
+### 5. Configure the Firewall
+Configure the firewall by running the following commands:
+
+    ufw allow ssh
+    ufw allow 80/tcp
+    ufw allow 443/tcp
+    ufw allow 3478/tcp
+    ufw allow 3478/udp
+    ufw allow 40000:57000/tcp
+    ufw allow 40000:57000/udp
+    ufw allow 57001:65535/tcp
+    ufw allow 57001:65535/udp
+    ufw --force enable
+
+### 6. Run OpenVidu
+You're ready to run OpenVidu! Run the following commands. Note there could be one or more long pauses, so be patient.
+
+You'll know it is ready when it presents the urls to you for access.  
+
+    cd /opt/openvidu/
+    ./openvidu start
