# nak, the nostr army knife
|
||||
|
||||
this repository contains two things:
|
||||
install with `go install github.com/fiatjaf/nak` 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.
|
||||
