+## Route discovery
+Specifiying routes by hand is not bad. But we could make it better by creating an executable `discover-routes` script in the project directory. If no routes are passed by hand, `xiringuito` will run `discover-routes`, pass SSH server hostname to it and use script output as a list of routes, so you may have per-host or per-domain route lists instead of boring manual typing. More information is available in [AWS example](https://github.com/ivanilves/xiringuito/blob/master/discover-routes.aws.example) which uses AWS CLI to discover VPC subnets and route traffic to them through our VPN tunnel.
+
+## You can have many of them!
+As long as your routes do not overlap, you can run as many `xiringuito` tunnels as you want. Simultaneously.
