 ## Authentication or login errors
 
-- **Error: `UNABLE_TO_GET_ISSUER_CERT_LOCALLY` or `unable to get local issuer certificate`**
+- **Error: `UNABLE_TO_GET_ISSUER_CERT_LOCALLY`, `UNABLE_TO_VERIFY_LEAF_SIGNATURE`, or `unable to get local issuer certificate`**
   - **Cause:** You may be on a corporate network with a firewall that intercepts and inspects SSL/TLS traffic. This often requires a custom root CA certificate to be trusted by Node.js.
   - **Solution:** Set the `NODE_EXTRA_CA_CERTS` environment variable to the absolute path of your corporate root CA certificate file.
     - Example: `export NODE_EXTRA_CA_CERTS=/path/to/your/corporate-ca.crt`
 
+- **Error: `Device authorization flow failed: fetch failed`**
+  - **Cause:** Node.js could not reach Qwen OAuth endpoints (often a proxy or SSL/TLS trust issue). When available, Qwen Code will also print the underlying error cause (for example: `UNABLE_TO_VERIFY_LEAF_SIGNATURE`).
+  - **Solution:**
+    - Confirm you can access `https://chat.qwen.ai` from the same machine/network.
+    - If you are behind a proxy, set it via `qwen --proxy <url>` (or the `proxy` setting in `settings.json`).
+    - If your network uses a corporate TLS inspection CA, set `NODE_EXTRA_CA_CERTS` as described above.
+
 - **Issue: Unable to display UI after authentication failure**
   - **Cause:** If authentication fails after selecting an authentication type, the `security.auth.selectedType` setting may be persisted in `settings.json`. On restart, the CLI may get stuck trying to authenticate with the failed auth type and fail to display the UI.
   - **Solution:** Clear the `security.auth.selectedType` configuration item in your `settings.json` file:

-- Selection Context: Qwen Code can easily access your cursor's position and selected text within the editor, giving it valuable context directly from your current work.
+## Features
 
-- Native Diffing: Seamlessly view, modify, and accept code changes suggested by Qwen Code directly within the editor.
+- **Native IDE experience**: Dedicated Qwen Code sidebar panel accessed via the Qwen icon
+- **Native diffing**: Review, edit, and accept changes in VS Code's diff view
+- **Auto-accept edits mode**: Automatically apply Qwen's changes as they're made
+- **File management**: @-mention files or attach files and images using the system file picker
+- **Conversation history & multiple sessions**: Access past conversations and run multiple sessions simultaneously
+- **Open file & selection context**: Share active files, cursor position, and selections for more precise help
 
-- Launch Qwen Code: Quickly start a new Qwen Code session from the Command Palette (Cmd+Shift+P or Ctrl+Shift+P) by running the "Qwen Code: Run" command.
+## Requirements
 
-# Requirements
+- Visual Studio Code 1.85.0 or newer
