 ## About LLVM
 
 clice calls Clang APIs to parse C++ code, so it must link against LLVM/Clang. Because clice uses Clang's private headers (usually absent from distro packages), the system LLVM package cannot be used directly.
 
 Two ways to satisfy this dependency:
 
-1. We publish prebuilt binaries of the LLVM version we use at [clice-llvm](https://github.com/clice-io/clice-llvm/releases) for CI and release builds. During builds, cmake and xmake download these LLVM libs by default.

 ## Debug
 
 If you want to attach a debugger to clice for debugging, it is recommended to first start clice in socket mode independently, and then connect the client to it.

 ## About LLVM
 
 clice 调用 Clang API 来解析 C++ 代码，因此必须链接 LLVM/Clang 库。由于 clice 使用了 Clang 的私有头文件（这些文件通常不包含在发行版中），不能直接使用系统安装的 LLVM 包。
 
 主要有两种方式解决这个依赖问题：
 
-1. 我们在 [clice-llvm](https://github.com/clice-io/clice-llvm/releases) 上会发布使用的 LLVM 版本的预编译二进制，用于 CI 或者 release 构建。在构建时 cmake 和 xmake 默认会从此处下载 LLVM 库然后使用。
