On Linux and macOS, extract the archive and move geblang onto your
PATH. Verify your download against checksums.txt in the
same release.
tar -xzf geblang_<version>_linux_amd64.tar.gz
sudo mv geblang /usr/local/bin/
geblang --version
On Windows, unzip the archive and add the folder containing
geblang.exe to your PATH.
macOS binaries are not yet notarized, so the first run may be blocked by
Gatekeeper; allow it under System Settings, or clear the quarantine attribute
with xattr -d com.apple.quarantine ./geblang.
