Install it on each computer you want to include, then connect it with the device key from your dashboard.
In the dashboard go to Admin → People, open the person and add a device. Copy the key.
Run the installer, then paste your server address and the device key.
The employee sees what is collected and agrees; capture starts after that.
Rolling out to many machines? Place a worklens-agent.json with serverUrl and deviceKey next to the app, or set WORKLENS_SERVER and WORKLENS_DEVICE_KEY.
On macOS, allow Worklens Agent under System Settings → Privacy & Security → Screen & System Audio Recording.
