 ### Updating the Chromium target version
 
 For the webview code, we use [esbuild](https://esbuild.github.io/) to bundle the code. This requires a target version of Chromium to be specified.
-This version should be the same as the version of Chromium that is bundled with the new minimum VS Code version. There are two

+This version should be the same as the version of Chromium that is bundled with the new minimum VS Code version. To update
+the version, run:
 
-#### Using the About Visual Studio Code dialog
-
-Download the new minimum VS Code version from [the previous release versions](https://code.visualstudio.com/docs/supporting/faq#_previous-release-versions). Then,
-select "About Visual Studio Code" from the top menu. This will show the version of Chromium that is bundled with that version of VS Code.

-#### Using the VS Code source code

-You can find the version of Electron that VS Code uses by looking at its `package.json` file for a specific version
-(for example [the `package.json` for `1.82.0`](https://github.com/microsoft/vscode/blob/1.82.0/package.json#L153)).
