 - Added [Virtual Pet](./../../../../../packages_demos/blob/trunk-5.4/pet/README.md) application: An interactive demo program based on the LVGL graphics library, simulating the process of raising a digital pet. Users can care for the virtual pet through operations like feeding, giving water, exercise, and rest to improve its mood and level.
 - [Snake Game](./../../../../../packages_demos/blob/trunk-5.4/snake_game/Readme.md): An automatic Snake game implemented using the LVGL graphics library.
 - [Electronic Wooden Fish](./../../../../../packages_demos/blob/trunk-5.4//wooden_fish/README_zh-cn.md): Based on the openvela `nxaudio` service and the upper-layer LVGL UI framework, implementing a complete interaction link containing responsive layout and secure resource management, realizing an application showcase with smooth animation effects, secure resource management, and a good user experience.
+## **7. Development Tools**
+- Ubuntu Environment VS Code Plugin Support
+  Support installing openvela VS Code plugin in Ubuntu environment, achieving full-process support from project creation, compilation and building, system debugging to application development, significantly improving development efficiency. ([openvela VS Code Plugin Usage Guide](../quickstart/vscode_plugin_usage.md))
+## **8. Emulator Runtime Parameter Extensions**
+- `emulator.sh` adds `-keep` parameter support
+  - If `emulator.sh` supports multi-instance configuration, you can access an instance with a specified name via the `-keep` parameter (creating it if it doesn't exist), and relevant contexts will not be deleted when that instance exits.
+  ```plaintext
+  # Usage
+  cp cmake_out/vela_goldfish-arm64-v8a-ap/nuttx* cmake_out/vela_goldfish-arm64-v8a-ap/vela_* cmake_out/vela_goldfish-arm64-v8a-ap/advancedFeatures.ini nuttx/
+
+  ./emulator.sh vela -keep -no-window
+
+  # Test example: create a test file in /data directory and write content
+  nsh> echo test > /data/test
+  nsh> echo "openvvela qemu keep test" >> /data/test
+  nsh> quit
+
+  # Exit emulator and re-enter, the previously written content is still preserved
+  ./emulator.sh vela -keep -no-window
+  nsh> cat /data/test
+  test
+  openvela qemu keep test
+  ```
+
+- `emulator.sh` adds support for using Hostfs function, default support using 9pfs, effect as follows:
+  ```Shell
+  goldfish-armv8a-ap> df -h
+    Filesystem      Size      Used  Available Mounted on
+    binfs             0B        0B         0B /bin
+    fatfs           255M       78M       177M /data
+    romfs          1152B     1152B         0B /etc
+    hostfs            0B        0B         0B /host
+    procfs            0B        0B         0B /proc
+    v9fs            878G      626G       252G /share
+    romfs           512B      512B         0B /system
+    tmpfs             6K        1K         5K /tmp
+  ```
+
+  Usage:
+  ```plaintext

+  - 如果 emulator.sh 支持多实例配置时，可以通过 `-keep` 参数接入指定的名称的实例（如果不存在则创建），并且在该实例退出时不会删除相关上下文
+  ```Shell
+  # 使用方法

+  ./emulator.sh vela -keep -no-window
+
+  # 测试举例，在/data目录创建 test 文件并写入内容
+  nsh> echo test > /data/test
+  nsh> echo "openvvela qemu keep test" >> /data/test
+  nsh> quit
+
+  # 模拟器退出重新进入，上一次写入的内容仍然被保留
+  ./emulator.sh vela -keep -no-window
+  nsh> cat /data/test
+  test
+  openvela qemu keep test
+  ```
+
+- emulator.sh 新增支持使用 Hostfs 功能，默认支持使用9pfs，效果如下：
+  ```Shell
