Description
It's common for new users to setup a remote node for testing the 101 materials and gets stuck needing the unsafe RPC and WS flags, as well as disabling mDNS and possibly other suggestions
I propose that we have a reference document (possible a how-to guide?) that we can point builders to that has a FAQ for unsafe remote nodes for dev/testing ONLY and points to further production resources to have nodes hosted with best practices (that we don't maintain on firewalls, rate limiting, rev, proxies, etc.)
Examples:
might need -- --rpc-cors=all
--ws-external
--rpc-external
