+# Ext Plug-in
+This plug-in is exposing some Eclipse Che API to be consumed by other VS Code extensions using the VS Code extension mechanism.
+
+## Example
+
+```typescript
+const eclipseCheExtPlugin = vscode.extensions.getExtension('@eclipse-che.ext-plugin');
+if (eclipseCheExtPlugin) {
+  // grab user
+  const user = yield eclipseCheExtPlugin.exports.user.getCurrentUser();
+  vscode.window.showInformationMessage(`Eclipse Che user information: id ${user.id} with name ${user.name}`);
+}
+```
+
+Exported code is coming from https://github.com/eclipse/che-theia/blob/master/extensions/eclipse-che-theia-plugin/src/che-proposed.d.ts
