Thank you for a feedback!
README updated with a fixed install, I missed @latest in the end.

I’ll work on a better README: https://github.com/yznts/dsh/issues/6.
I’m not that good at this kind of thing :)

For now, only url-like DSNs are supported, like:

• postgres://user:pass@host:port/db?options
• sqlite://file.db
