Greetings my dear friend!
If you see this page, then it probably means that you have indeed successfully created a lovely project and launched a lovely server. Congratulations on that!
But, it seems you didn't have the /index.html page in your project directory, so I took the liberty and served you one from my own stash of shared resources.
Look into the ~/.lovely/server/ folder when you have a moment. You will find this and some other pages over there, which you might want to use in your projects.

Sincerely Yours,
Lovely Server
