Hey there - 我已经审阅了你的改动，这里有一些反馈：

• 内联安装脚本目前把 aarch64 版的 Miniconda 安装程序（Miniconda3-py310_25.9.1-3-Linux-aarch64.sh）写死在脚本里了。建议要么在文档中说明本指南只适用于 aarch64，要么增加一个简单的架构检测逻辑（例如通过 uname -m），根据架构选择正确的安装程序。
• 由于脚本会在当前目录写入 install-py310.sh，建议在脚本末尾将其清理掉（rm install-py310.sh），或者在文档中说明会生成这个文件，以便用户知道脚本执行后会留下什么。
• Miniconda 的下载 URL 目前固定到一个特定版本并使用清华镜像；你可以考虑补充一个简短说明或备用 URL，以便境外用户使用，或者在该版本不再可用时仍有替代方案。

Hey there - I've reviewed your changes - here's some feedback:

• The inline install script hardcodes the aarch64 Miniconda installer (Miniconda3-py310_25.9.1-3-Linux-aarch64.sh), so consider either documenting that this guide only applies to aarch64 or adding simple architecture detection logic (e.g., via uname -m) to pick the correct installer.
• Since the script writes install-py310.sh into the current directory, it would be helpful to either clean it up at the end (rm install-py310.sh) or mention that this file will be created so users understand what’s left behind.
• The Miniconda download URL is pinned to a specific version and a Tsinghua mirror; you may want to add a brief note or alternative URL for users outside mainland China or for when this specific version becomes unavailable.
