Roadmap
A CI integration hook is planned but not implemented yet. It's also a harder lift than it sounds: licenses here are activated per-machine inside a running VS Code window (see how @batch2/license-client stores activation), which a headless CI runner has no access to — shipping this well needs a separate offline-verifiable license artifact and a standalone CLI, not just a setting.
Getting a license
Open the BenchMark Pin sidebar (activity bar icon) and click Get License. After purchase you'll receive a license key — paste it into the sidebar and click Activate License. Keys are machine-locked; use Move to another machine… in the sidebar before reinstalling on a new device.
