 - Optimized gcode for printing on Snapmaker 2 (no scanning)
 - Model thumbnails are displayed on touchscreen
+- Smart pre-heat for switch tools, shutoff nozzles that are no longer in use, and other optimization features for multi-extruders.
 - Support for multiple platforms including win/macOS/Linux
 
 ## Install
-- Download [smfix-{platform}-{arch}](https://github.com/macdylan/Snapmaker2Slic3rPostProcessor/releases)
+- Download [Latest version](https://github.com/macdylan/Snapmaker2Slic3rPostProcessor/releases)
     - Linux/macOS: `chmod +x smfix`
+    - macOS prohibits opening unsigned programs. Please refer to the [solution](https://osxdaily.com/2012/07/27/app-cant-be-opened-because-it-is-from-an-unidentified-developer/):
+        - Remove the restriction by execute in terminal: `xattr -d com.apple.quarantine /path/to/smfix-darwin`
+
 - PrusaSlicer Settings：
     1. `Printer Settings - Firmware - G-code thumbnails: 220x124`
     2. `Print Settings - Output options - Post-processing scripts: /path/to/smfix`
 - Slice and export gcode file
-- You can use [SM2Uploader](https://github.com/macdylan/sm2uploader) to quickly upload files to the printer
+- Alternatively, you can also use this tool separately in the Terminal. For specific instructions, please refer to the information provided in the `-h` flag.
+
+If you are unable to utilize advanced features such as smart pre-heat or disabling inactive nozzles on your multi-extruders(J1 / Dual-extruder Module), it is possible that there is something mistakes in your slicer settings. You can directly use [my configuration parameters](https://github.com/macdylan/3dp-configs) as an alternative.

+- 为多挤出机提供智能预热、关闭不再使用的喷头等优化功能
 - 支持平台 Win/macOS/Linux
 
 ## 安装说明：
-- [下载](https://github.com/macdylan/Snapmaker2Slic3rPostProcessor/releases) 适用于你设备的文件
+- [下载](https://github.com/macdylan/SMFix/releases) 适用于你设备的文件
     - Linux/macOS 下可能需要赋予可执行权限: `chmod +x smfix`

+        - 去除限制，在终端执行 `xattr -d com.apple.quarantine /path/to/smfix-darwin`
+
 - PrusaSlicer 设置参数：
     1. 打印机设置 - 固件 - Gcode缩略图：220x124
     2. 打印设置 - 输出选项 - Post-processing：/path/to/smfix （建议路径不要有空格）
 - 设置完成，切片并导出 Gcode 即可
-- 如果希望更快的完成文件上传，可以使用 [SM2Uploader](https://github.com/macdylan/sm2uploader)，参考[快速设置说明](https://github.com/macdylan/sm2uploader/wiki)。
+- 也可以在终端里单独使用这个工具，具体请参考 `-h` 的说明信息
+
+在多挤出机上使用本工具，如果无法实现智能预热、关闭停用的喷头等高级功能，可能是你的切片软件设置错误。你可以直接使用[我的配置参数](https://github.com/macdylan/3dp-configs)。
