+> **Dev builds:** Pre-release tarballs are attached to [GitHub Releases](https://github.com/optave/codegraph/releases). Install with `npm install -g <path-to-tarball>`. Note that `npm install -g <tarball-url>` does not work because npm cannot resolve optional platform-specific dependencies from a URL — download the `.tgz` first, then install from the local file.
