-# nostr army knife
+# nak, the nostr army knife

-this repository contains two things:
+install with `go install github.com/fiatjaf/nak@latest` or
+[download a binary](https://github.com/fiatjaf/nak/releases).

-## a command-line tool for decoding and encoding nostr entities and talking to relays
+## what can you do with it?

-Install with `go install github.com/fiatjaf/nak`.
+take a look at the help text that comes in it to learn all possibilities, but here are some:

-It pairs nicely with https://github.com/blakejakopovic/nostcat using unix pipes.
