 This is a Heft plugin for running Jest.
 
+## VSCode Jest Extension Integration
+
+This package includes a `heft-jest` CLI wrapper that enables integration with the
+[VSCode Jest extension](https://github.com/jest-community/vscode-jest). The wrapper translates
+Jest CLI parameters to Heft CLI parameters, allowing the extension to work with Heft's test
+runner.
+
+### Setup
+
+To use the VSCode Jest extension with Heft, configure the extension's `jest.jestCommandLine`
+setting in your VSCode workspace settings (`.vscode/settings.json`):
+
+```json
+{
+  "jest.jestCommandLine": "npx heft-jest"
+}
+```
+
+Or, if you have `@rushstack/heft-jest-plugin` installed globally or linked:
+
+```json
+{
+  "jest.jestCommandLine": "heft-jest"
+}
+```
+
+### How It Works
+
+The `heft-jest` CLI accepts Jest CLI parameters commonly sent by the VSCode Jest extension and
+translates them to equivalent Heft parameters. For example:
+
+| Jest Parameter | Heft Parameter |
+|----------------|----------------|
+| `--testPathPattern` | `--test-path-pattern` |
+| `--testNamePattern` or `-t` | `--test-name-pattern` |
+| `--updateSnapshot` or `-u` | `--update-snapshots` |
+| `--maxWorkers` | `--max-workers` |
+| `--testTimeout` | `--test-timeout-ms` |
+| `--no-coverage` | `--disable-code-coverage` |
+| `--detectOpenHandles` | `--detect-open-handles` |
+| `--silent` | `--silent` |
+| `--logHeapUsage` | `--log-heap-usage` |
+| `--watchAll` / `--watch` | Uses `heft test-watch` instead of `heft test` |
+
+Parameters specific to the VSCode Jest extension (like `--json`, `--outputFile`, `--reporters`)
+are automatically filtered out.
