This page contains links to static binaries for Linux. These were linked against the musl C library, so they should work out of the box on most i686 or x86-64 Linux machines. The binary for a given architecture is packaged in a gzipped tar file. It unpacks to a directory named for the architecture. So just extract the archive appropriate for your system and copy the binary to a directory in your $PATH.
All packages are signed with my gpg key, and the key ID is 6521E06D. Here is its fingerprint:
66BD 74A0 36D5 22F5 1DD7 0A3C 7F2A 1672 6521 E06D
You should be able to fetch that key from a keyserver. Also, you can download it from my site using this link: download Chris’s gpg key. I suggest verifying the binary against my key, so you can at least have some confidence that you are using a binary that did in fact come from me.
