In Expander, you can add notes to individual assets as a way to provide additional context about the asset. Notes can be added to all asset types except services and websites, and are limited to 1024 characters. Notes are displayed as a field in the Inventory, so you can filter and sort on them. Notes are also displayed on the Assets tab of incidents. You can add or edit Notes on the asset details pane or on the Assets tab of an incident.
