+.SH NAME
+argon2 \- generate argon2 hashes
+
+.SH SYNOPSIS
+.B argon2 salt
+.RB [ OPTIONS ]
+
+.SH DESCRIPTION
+Generate Argon2 hashes from the command line.
+
+The supplied salt (the first argument to the command) must be at least
+8 octets in length, and the password is supplied on standard input.
+
+By default, this uses Argon2i variant (where memory access is
+independent of secret data) which is the preferred one for password
+hashing and password-based key derivation.
+
+.SH OPTIONS
+.TP
+.B \-h

+.TP
+.B \-d

+.TP
+.BI \-t " N"
+Sets the number of iterations to N (default = 3)
+.TP
+.BI \-m " N"
+Sets the memory usage of 2^N KiB (default = 12)
+.TP
+.BI \-p " N"
+Sets parallelism to N threads (default = 1)
+.TP
+.BI \-l " N"
