   Right click on the latest Linux archive in google drive and select "Get shareable link..."

   The id at the end of this URL should be used in the command

4. Copy to the running instance and execute the script. You will be prompted with instructions for a Google Drive verification code.

   $ scp -i [pem identity file name] install_rai_node.sh ubuntu@[instance public ip]:~
   $ ssh -i [pem identity file name] ubuntu@[instance public ip]
   
   # In ssh session:
   $ chmod +x install_rai_node.sh
   $ ./install_rai_node.sh

5. Test an RPC call to the node from your local machine

   curl -d '{ "action" : "block_count" }' [instance public ip]:7076
