const msg = `hii,
I want to run this ysws called Teapot (#teapot)
[ name comes from HTTP/1.1 418 I'm a teapot; see the headers! ]

Basically:

- YS: ANYTHING that speaks HTTP: an api, a graphql server, api clients, reverse proxy, load balancer, tunnels
- WS: Stickers, Domain Grants, AI Grants, Raspberry Pis, .... TEA! .... and more...
- projects must implement HTTP meaningfully and contain 418 I'm a teapot somewhere.

If you like it, consider joining #teapot <3 thanks!
