Download, extract, and verify the tarball corresponding to the desired platform then put the fnc executable on your $PATH (e.g., /usr/local/bin).

n.b. Package maintainers may prefer to retrieve a fossil generated tarball: https://fnc.bsdbox.org/tarball/0.18/fnc-0.18.tar.gz
Change 0.18 in the URL to the desired version number.

The SHA256 checksum of each tarball is cryptographically signed with signify(1). Verify release artifacts with either of the following methods:

1. in the root of an fnc work tree with the release tarball in the current directory:

   fossil wiki export -t $uname-$version | signify -Cp signify/fnc-$version-release.pub -x -

2. anywhere in the filesystem with fnc's public key,^♱ the release tarball, and its SHA256.sig file in the current directory:

   signify -C -p fnc-$version-release.pub -x fnc$version-$uname.tar.gz.SHA256.sig

Exemplar authenticated response for an fnc 0.18 source tarball:

>: fossil wiki export -t src-0.18 | signify -Cp signify/fnc-18-release.pub -x -
Signature Verified
fnc-0.18.tar.gz: OK

^♱Alternatively, retrieve a copy of the public key stored on DNS:

dig -t txt pk.bsdbox.org +noall +short | tr -d '\"' | tr ';' '\n'

The public key has also been encoded into the following QR code symbol:
