Where do I add my Manifyst license key?

Add your license key in WordPress under Manifyst → Settings → Licenses, using the "Manage License" control.

Steps:

1. In the WordPress admin menu, go to Manifyst → Settings.
2. Open the Licenses tab. It shows Manifyst's current license status and a "Manage License" button.
3. Click "Manage License". In the panel that opens, paste your license key and confirm.

Once the key is saved, the row shows the license as Active along with its expiration date.
