-ScanCode Workbench provides an advanced visual UI to help you quickly evaluate
-license and other notices identified by
-[ScanCode](https://github.com/aboutcode-org/scancode-toolkit/).
-[ScanCode](https://github.com/aboutcode-org/scancode-toolkit/) detects licenses,
-copyrights and other interesting information in your code.
-
-ScanCode Workbench is based on [Electron](https://www.electronjs.org/) and will
-be the primary desktop/GUI tool for using nexB’s
-[AboutCode tools](https://github.com/nexB/aboutcode). This app works on Windows,
-macOS and Linux operating systems.
+ScanCode Workbench provides a visual UI (GUI) to help you quickly evaluate
+license, copyright and other important information from a
+[ScanCode Toolkit](https://github.com/aboutcode-org/scancode-toolkit/) scan.
+
+The Workbench is a single-user desktop application that works on Windows,
+macOS, and Linux operating systems. There is no current or planned future 
+functionality to edit or update scan results - the Scan data is read-only.
+
+If you need a multi-user application for running or reviewing ScanCode scans,
+you should use [ScanCode.io](https://github.com/aboutcode-org/scancode.io) 
+instead of ScanCode Workbench. You cannot edit scan data in ScanCode.io, but 
+you can export the scan data in SBOM, XLSX and other formats for further 
+analysis and processing. You can also import a ScanCode Toolkit scan into
+ScanCode.io using the `load_inventory` pipeline.
+
+If you need an application to review and edit ScanCode scan data or to convert
+that data into an SBOM or a software inventory, you should use [DejaCode](https://github.com/aboutcode-org/dejacode). You can import scan data from ScanCode Toolkit or ScanCode.io into DejaCode or you can import an SBOM. The DejaCode
+Dashboard provides immediate visibility into license or vulnerability issues
+related to your products, components and packages. You can use the [DejaCode demo system](https://public.dejacode.com/account/register/) for quick access to its
+features and functions.
