## How to setup a TURN server for free (or near free)

# Create a VM instance on Google Cloud (Free Tier available)
# Use Ubuntu and Open all PORTS for ingress/egress for TCP/UDP
#>> sudo apt-get update
#>> sudo apt-get install coturn
# Set a domain name to point to the server you setup. I use https://namecheap.com to buy a $1 .xyz domain
#>> sudo add-apt-repository ppa:certbot/certbot
#>> sudo apt-get install certbot
#>> sudo certbot certonly --standalone  ## do the wizard , which will setup a SSH key for you
# edit /etc/default/coturn and set TURNSERVER_ENABLED=1
# edit THIS file with required changes; CHANGE ME.
# put the edited file @ /etc/turnserver.conf
#>> systemctl start coturn
# Use with obs.ninja by adding: https://obs.ninja/?streamid=XXXXXXXXXXX&turn=steve;justtesting;turn:turn.obs.ninja:443  
# Obviously update the TURN settings with your domain, username, and password -- keep the password private.
