 # Build from Source
 
-## Supported Platforms
+clice depends on C++23 features and requires a modern C++ toolchain. We also need to link against LLVM/Clang to parse ASTs. To speed up builds, the default configuration downloads our published [clice-llvm](https://github.com/clice-io/clice-llvm) prebuilt package. This assumes your local environment matches the prebuilt environment closely (especially when enabling Address Sanitizer or LTO).
 
-- Windows
-- Linux
-- MacOS
+To simplify setup and keep builds reproducible, we **strongly recommend** [pixi](https://pixi.prefix.dev/latest) to manage the development environment. Dependency versions are pinned in `pixi.toml`.
 
-## Prerequisite
+If you prefer not to use pixi, see [Manual Build](#manual-build) below.
 
-- cmake/xmake
-- clang, lld >= 20
-- c++23 **compatible** standard library
-  - MSVC STL >= 19.44(VS 2022 17.4)
-  - GCC libstdc++ >= 14
-  - Clang libc++ >= 20
+## Quick Start
 
-clice uses C++23 as its language standard. Please ensure you have a clang 20 (or higher) compiler and a C++23 compatible standard library available. clice depends on lld as its linker. Please ensure your clang toolchain can find it (clang distributions usually bundle lld, or you may need to install the lld-20 package separately).
+Install pixi following the [official guide](https://pixi.prefix.dev/latest/installation).
 
-> clice is currently only guaranteed to compile with clang (as ensured by CI testing). We do our best to maintain compatibility with gcc and msvc, but we do not add corresponding tests in CI. Contributions are welcome if you encounter any issues.
-
-## CMake
-
-Use the following commands to build clice
+We ship several tasks; the commands below configure, build, and run tests:
 
 ```shell
-cmake -B build -DCMAKE_BUILD_TYPE=RelWithDebInfo -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++
-cmake --build build
+# configure && build (default RelWithDebInfo)
+pixi run build
+
+# unit && integration
+pixi run test
 ```
 
+For finer-grained tasks (first argument sets the build type):
+
+```shell
+pixi run cmake-config Debug
+pixi run cmake-build Debug
+pixi run unit-test Debug
+pixi run integration-test Debug
+```
+
+> [!TIP]
+> If you want to develop directly with `cmake`, `ninja`, `clang++`, etc., run `pixi shell` to enter a shell with all env vars configured.
+
+### XMake
+
+We also support building with XMake:
+
+```shell
+# config & build (default releasedbg)
+pixi run xmake
+
+# unit & integration
+pixi run xmake-test
+```
+
+## Manual Build
+
+If you plan to build manually, first ensure your toolchain matches the versions defined in `pixi.toml`.
+
+> Compatibility: In theory clice does not rely on compiler-specific extensions, so mainstream compilers (GCC/Clang/MSVC) should work. However, CI only guarantees specific versions of Clang. Other compilers or versions are supported on a **best-effort** basis. Please open an issue or PR if you hit problems.
+
+### CMake
+
+```shell
+cmake -B build -G Ninja \
+    -DCMAKE_BUILD_TYPE=RelWithDebInfo \
+    -DCMAKE_TOOLCHAIN_FILE=cmake/toolchain.cmake \
+    -DCLICE_ENABLE_TEST=ON
+```
+
+> Note: `CMAKE_TOOLCHAIN_FILE` is optional. If your toolchain exactly matches ours, you can use the predefined `cmake/toolchain.cmake`; otherwise remove that flag.
+

-## A Note on LLVM Libs
+## About LLVM
 
-Due to the complexity of C++ syntax, writing a new parser from scratch is unrealistic. clice calls clang's APIs to parse C++ source files and obtain the AST, which means it needs to link against llvm/clang libs. Because clice uses clang's private headers, which are not included in the binary releases published by LLVM, you cannot use the system's llvm package directly.
+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.
 
-1. We publish pre-compiled binaries for the LLVM version we use on [clice-llvm](https://github.com/clice-io/clice-llvm/releases), which are used for CI or release builds. By default, cmake and xmake will download and use the llvm libs from here during the build.
+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.
 
 > [!IMPORTANT]
 >
-> For debug builds of llvm libs, we enable address sanitizer. Address sanitizer depends on compiler-rt, which is highly sensitive to the compiler version.
->
-> Therefore, if you use a debug build, please ensure your clang's compiler-rt version is **strictly identical** to the one used in our build.
->
-> - Windows does not currently have debug builds for llvm libs, as it does not support building clang as a dynamic library. Related progress is tracked [here](https://github.com/clice-io/clice/issues/42).
-> - Linux uses clang20
-> - MacOS uses homebrew llvm@20. **Do not use apple clang**.
->
-> You can refer to the [cmake](https://github.com/clice-io/clice/blob/main/.github/workflows/cmake.yml) and [xmake](https://github.com/clice-io/clice/blob/main/.github/workflows/xmake.yml) files in our CI as a reference, as they maintain an environment strictly consistent with the pre-compiled llvm libs.
+> For debug LLVM builds, we enable address sanitizer, which depends on compiler-rt and is very sensitive to compiler version. If you use a debug build, ensure your clang compiler-rt version matches the one defined in `pixi.toml`.
 
-2. Build llvm/clang yourself to match your current environment. If the default pre-compiled binaries (Method 1) fail to run on your system due to ABI or library version (e.g., glibc) incompatibility, or if you need a custom Debug build, we recommend you use this method to compile llvm libs from scratch. We provide a script to build the llvm libs required by clice: [build-llvm-libs.py](https://github.com/clice-io/clice/blob/main/scripts/build-llvm-libs.py).
-
-```bash
-cd llvm-project
-python3 <clice>/scripts/build-llvm-libs.py debug
-```

+# Builtin Libraries
+
+Builtin libraries are compiled directly into the `clice` binary instead of being loaded later with `--plugin-path`.
+
+This is useful when:
+
+- your plugin sources live outside the `clice` source tree
+- you want the builtin to be part of the default executable
+- you need extra include directories, compile definitions, or link dependencies during the main build
+
+## CMake Entry Point
+
+`clice` now exposes a small helper module at [cmake/builtin-libraries.cmake](/cmake/builtin-libraries.cmake).
+
+Extra builtin libraries are registered through the cache variable `CLICE_BUILTIN_LIBRARY_MODULES`.
+
+Each value in `CLICE_BUILTIN_LIBRARY_MODULES` must be a CMake file. During configure, `clice` includes those files, and each file calls `clice_add_builtin_library(...)`.
+
+## Minimal Module
+
+Create a CMake file in your external project, for example `/path/to/my-plugin/clice-builtin.cmake`:
+
+```cmake
+clice_add_builtin_library(
+    NAME my_plugin
+    SOURCES
+        "${CMAKE_CURRENT_LIST_DIR}/src/MyPlugin.cpp"
+    INCLUDE_DIRECTORIES
+        "${CMAKE_CURRENT_LIST_DIR}/include"
+    ENTRYPOINT
+        clice_get_my_plugin_server_plugin_info
+)
+```
+
+Then configure `clice` with:
+
+```shell
+cmake -B build -G Ninja \
+    -DCLICE_BUILTIN_LIBRARY_MODULES="/path/to/my-plugin/clice-builtin.cmake"
+```
+
+To load multiple modules, pass a semicolon-separated CMake list:
+
+```shell
+cmake -B build -G Ninja \
+    -DCLICE_BUILTIN_LIBRARY_MODULES="/path/to/a.cmake;/path/to/b.cmake"
+```
+
+## `clice_add_builtin_library`
+
+The helper accepts the following arguments:
+
+| Argument | Required | Description |
+| --- | --- | --- |
+| `NAME` | Yes | Logical name used to create an internal object target |
+| `SOURCES` | Yes | Source files compiled into `clice`; absolute paths and out-of-tree paths are supported |
+| `ENTRYPOINT` | Yes | Unique function name in namespace `clice` that returns `::clice::PluginInfo` |
+| `INCLUDE_DIRECTORIES` | No | Extra include directories for this builtin only |
+| `LINK_LIBRARIES` | No | Extra libraries or targets needed by this builtin |
+| `COMPILE_DEFINITIONS` | No | Extra compile definitions for this builtin |
+| `COMPILE_OPTIONS` | No | Extra compile options for this builtin |
+
+## Entrypoint Requirements
+
+Builtin libraries share a single final executable, so each builtin must use its own unique entrypoint function inside namespace `clice`.
+
+Dynamic plugins use:
+
+```cpp
+clice_get_server_plugin_info()
+```
+
+Builtin libraries should use a unique name such as:
+
+```cpp
+clice_get_my_plugin_server_plugin_info()
+```
+
+For example:
+
+```cpp
+#include "Server/Plugin.h"
+
+namespace clice {
+
+::clice::PluginInfo clice_get_my_plugin_server_plugin_info() {
+    return {
+        CLICE_PLUGIN_API_VERSION,
+        "MyPlugin",
+        "v0.0.1",
+        CLICE_PLUGIN_DEF_HASH,
+        [](clice::ServerPluginBuilder& builder) {
+            // register callbacks here
+        },
+    };
+}
+
+}  // namespace clice
+```
+
+`clice` generates the static registration glue automatically, so once the module is included, no additional edits to `src/clice.cc` are required.

+# Extension
+
+This section covers development and release workflows for the editor extensions (VSCode / Neovim / Zed).
+
+## VSCode
+
+The VSCode extension uses the Node/PNPM/VSCE toolchain. Work inside the pixi `node` environment for consistent versions.
+
+```shell
+# prepare environment (install pixi first)
+pixi shell -e node
+
+# install deps (uses pnpm-lock)
+pixi run install-vscode
+
+# package the extension; outputs editors/vscode/*.vsix
+pixi run build-vscode
+```
+
+Publish to the VSCode Marketplace (`VSCE_PAT` env var required):
+
+```shell
+pixi run publish-vscode
+```
+
+> [!TIP]
+> If clice is already built locally, set `clice.executable` in VSCode settings to point the extension to your custom binary.
+
+Develop and debug:
+
+1. `pixi shell -e node`
+2. In `editors/vscode`, run `pnpm run watch` for incremental builds
+3. In VSCode, use the “Run Extension/Launch Extension” configs, or run `code --extensionDevelopmentPath=$(pwd)/editors/vscode`
+
+Common scripts (inside `pixi shell -e node`):
+
+```bash
+pnpm run package # same as pixi run build-vscode
+pnpm run publish # same as pixi run publish-vscode
+```
+
+If you skip pixi, install node.js >= 20 and pnpm yourself, then in `editors/vscode` run:
+
+```bash
+pnpm install
+pnpm run package
+```
+
+## Neovim
+
+The Neovim extension lives in `editors/nvim` and is written in Lua. It is still evolving.
+
+- Add the repo path to `runtimepath`, e.g. `set rtp+=/path/to/clice/editors/nvim`
+- Or create a local symlink: `~/.config/nvim/pack/clice/start/clice` -> `<repo>/editors/nvim`
+- Ensure the `clice` executable is discoverable in `$PATH`
+
+Dev tips: the codebase is small—load it directly in Neovim and watch `:messages`/LSP logs; format with `stylua` (config included).
+
+## Zed
+
+The Zed extension lives in `editors/zed` and uses Rust plus `zed_extension_api`.
+
+Suggested local verification:
+
+```bash
+cd editors/zed
+cargo build --release
+```
+
+Then load the local extension per Zed's official guide (Zed CLI required). Make sure `clice` is on `PATH` before launching. Follow the Zed extension publishing flow when releasing.

+You can implement a clice server plugin to extend clice's functionality.
+
+## Use case
+
+When you use `clice` as LSP backend of LLM agents, e.g. claude code, you can add plugin to provide some extra features.
+
+## Writing a plugin
+
+When a plugin is loaded by the server, it will call `clice_get_server_plugin_info` to obtain information about this plugin and about how to register its customization points.
+
+This function needs to be implemented by the plugin, see the example below:
+
+```c++
+extern "C" ::clice::PluginInfo LLVM_ATTRIBUTE_WEAK
+clice_get_server_plugin_info() {
+  return {
+    CLICE_PLUGIN_API_VERSION, "MyPlugin", "v0.1", CLICE_PLUGIN_DEF_HASH,
+    [](ServerPluginBuilder builder) {  ... }
+  };
+}
+```
+
+See [PluginProtocol.h](/include/Server/PluginProtocol.h) for more details.
+
+## Compiling a plugin
+
+The plugin must be compiled with the same dependencies and compiler options as clice, otherwise it will cause undefined behavior. [config/llvm-manifest.json](/config/llvm-manifest.json) defines the build information used by clice.
+
+## Loading plugins
+
+For security reasons, clice does not allow loading plugins through configuration files, but must specify the plugin path through command line options.
+
+When `clice` starts, it will load all plugins specified in the command line. You can specify the plugin path through the `--plugin-path` option.
+
+```shell
+$ clice --plugin-path /path/to/my-plugin.so
+```
+
+## Getting content of `CLICE_PLUGIN_DEF_HASH`
+
+There are two values to return in the `clice_get_server_plugin_info` function.
+
+- `CLICE_PLUGIN_API_VERSION` is used to ensure compability of the `clice_get_server_plugin_info` function between the plugin and the server.
+- `CLICE_PLUGIN_DEF_HASH` is used to ensure the consistency of the C++ declarations between the plugin and the server.
+
+To debug the content of `CLICE_PLUGIN_DEF_HASH`, you can run following command:
+
+```shell
+$ git clone https://github.com/clice-io/clice.git
+$ cd clice
+$ git checkout `clice --version --git-describe`
+$ python scripts/plugin-def.py content
+```
+
+You will get a C source code file, content of which is like this:
+
+```cpp
+#if 0
+// begin of config/llvm-manifest.json
+[
+  {
+    "version": "21.1.4+r1",
+    "filename": "arm64-macos-clang-debug-asan.tar.xz",
+    "sha256": "7da4b7d63edefecaf11773e7e701c575140d1a07329bbbb038673b6ee4516ff5",

+#endif
+```

 # Build from Source
 
-## Supported Platforms
+clice 依赖 C++23 特性，需要使用高版本的 C++ 编译器。同时，我们需要链接 LLVM/Clang 库来解析 AST。为了加快构建速度，默认配置会下载我们发布的 [clice-llvm](https://github.com/clice-io/clice-llvm) 预编译包。这要求你的本地环境与预编译环境保持较高的一致性（尤其是开启 Address Sanitizer 或 LTO 时）。
 
-- Windows
-- Linux
-- MacOS
+为了简化环境设置并保证可复现性，我们**强烈推荐**使用 [pixi](https://pixi.prefix.dev/latest) 来管理开发环境。所有的依赖版本均严格定义在 `pixi.toml` 中。
 
-## Prerequisite
+如果你不想使用 pixi，请参考下方的 [Manual Build](#manual-build) 章节。
 
-- cmake/xmake
-- clang, lld >= 20
-- c++23 **compatible** standard library
-  - MSVC STL >= 19.44(VS 2022 17.4)
-  - GCC libstdc++ >= 14
-  - Clang libc++ >= 20
+## Quick Start
 
-clice 使用 C++23 作为语言标准，请确保有可用的 clang 20 以及以上的编译器，以及兼容 C++23 的标准库。clice 依赖 lld 作为链接器。请确保你的 clang 工具链可以找到它（通常 clang 发行版会自带 lld，或者你需要单独安装 lld-20 包）。
+请参考 [pixi](https://pixi.prefix.dev/latest/installation) 官方指南安装 pixi。
 
-> clice 目前只保证能使用 clang 编译（CI 测试保证）。对于 gcc 和 msvc 的兼容，我们尽力而为，但不会在 CI 中添加对应的测试。如果遇到任何问题，欢迎贡献。

-cmake --build build
+# configure && build (default RelWithDebInfo)
+pixi run build
+
+# unit && integration
+pixi run test
 ```
 
+细粒度任务：上述命令由多个子任务组成，你也可以单独运行它们，并支持通过第一个参数指定构建类型：
+
+```shell
+pixi run cmake-config Debug
+pixi run cmake-build Debug
+pixi run unit-test Debug
+pixi run integration-test Debug
+```

+我们同样支持使用 XMake 构建：
+
+```shell
+# config & build (default releasedbg)
+pixi run xmake
+
+# unit & integration
+pixi run xmake-test

-## A Note on LLVM Libs
+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。
 
-由于 C++ 的语法太过复杂，自己编写一个新的 parser 是不现实的。clice 调用 clang 的 API 来 parse C++ 源文件获取 AST，这意味它需要链接 llvm/clang libs。由于 clice 使用了 clang 的私有头文件，这些私有头文件在 llvm 发布的 binary release 中是没有的，所以不能直接使用系统的 llvm package。

+# Builtin Libraries
+
+Builtin library 会被直接编译进 `clice` 可执行文件，而不是在运行时通过 `--plugin-path` 动态加载。
+
+这种方式适合以下场景：
+
+- 插件源码位于 `clice` 源码树之外
+- 希望该 builtin 默认随 `clice` 可执行文件一起发布
+- 需要为该 builtin 单独补充 include 路径、编译宏或链接依赖
+
+## CMake 入口
+
+`clice` 现在提供了一个辅助模块：[cmake/builtin-libraries.cmake](/cmake/builtin-libraries.cmake)。
+
+额外的 builtin library 通过缓存变量 `CLICE_BUILTIN_LIBRARY_MODULES` 注册。
+
+`CLICE_BUILTIN_LIBRARY_MODULES` 中的每一项都必须是一个 CMake 文件。配置阶段 `clice` 会 `include()` 这些文件，而每个文件都需要调用 `clice_add_builtin_library(...)`。
+
+## 最小示例
+
+你可以在外部项目中创建一个 CMake 文件，例如 `/path/to/my-plugin/clice-builtin.cmake`：
+
+```cmake
+clice_add_builtin_library(
+    NAME my_plugin
+    SOURCES
+        "${CMAKE_CURRENT_LIST_DIR}/src/MyPlugin.cpp"
+    INCLUDE_DIRECTORIES
+        "${CMAKE_CURRENT_LIST_DIR}/include"
+    ENTRYPOINT
+        clice_get_my_plugin_server_plugin_info
+)
+```
+
+然后在配置 `clice` 时传入：
+
+```shell
+cmake -B build -G Ninja \
+    -DCLICE_BUILTIN_LIBRARY_MODULES="/path/to/my-plugin/clice-builtin.cmake"
+```
+
+如果要加载多个模块，可以传入以分号分隔的 CMake 列表：
+
+```shell
+cmake -B build -G Ninja \
+    -DCLICE_BUILTIN_LIBRARY_MODULES="/path/to/a.cmake;/path/to/b.cmake"
+```
+
+## `clice_add_builtin_library`
+
+该辅助函数支持以下参数：
+
+| 参数 | 必填 | 说明 |
+| --- | --- | --- |
+| `NAME` | 是 | 逻辑名称，会用于创建内部 object target |
+| `SOURCES` | 是 | 要编译进 `clice` 的源文件，支持绝对路径和源码树外路径 |
+| `ENTRYPOINT` | 是 | `clice` 命名空间中的唯一函数名，返回值类型为 `::clice::PluginInfo` |
+| `INCLUDE_DIRECTORIES` | 否 | 仅对当前 builtin 生效的额外头文件目录 |
+| `LINK_LIBRARIES` | 否 | 当前 builtin 额外需要的库或 target |
+| `COMPILE_DEFINITIONS` | 否 | 当前 builtin 额外需要的编译宏 |
+| `COMPILE_OPTIONS` | 否 | 当前 builtin 额外需要的编译选项 |
+
+## Entrypoint 要求
+
+所有 builtin library 最终都会被链接进同一个可执行文件，因此每个 builtin 都必须在 `clice` 命名空间中使用唯一的入口函数名。
+
+动态插件通常使用：
+
+```cpp
+clice_get_server_plugin_info()
+```
+
+builtin library 应该改用类似下面的唯一名字：
+
+```cpp
+clice_get_my_plugin_server_plugin_info()
+```
+
+例如：
+
+```cpp
+#include "Server/Plugin.h"
+
+namespace clice {
+
+::clice::PluginInfo clice_get_my_plugin_server_plugin_info() {
+    return {
+        CLICE_PLUGIN_API_VERSION,
+        "MyPlugin",
+        "v0.0.1",
+        CLICE_PLUGIN_DEF_HASH,
+        [](clice::ServerPluginBuilder& builder) {
+            // 在这里注册回调
+        },
+    };
+}
+
+}  // namespace clice
+```
+
+`clice` 会自动生成静态注册代码，因此只要模块被包含进来，就不需要再手动修改 `src/clice.cc`。

+# Extension
+
+本节汇总各编辑器插件的开发与发布流程。目前包含 VSCode / Neovim / Zed。
+
+## VSCode
+
+VSCode 插件使用 Node/PNPM/VSCE 链路。推荐在 pixi 的 `node` 环境下操作以获得一致的工具链版本。
+
+```shell
+# 准备环境（先安装 pixi）
+pixi shell -e node
+
+# 安装依赖（基于 pnpm-lock）
+pixi run install-vscode
+
+# 打包扩展，产物位于 editors/vscode/*.vsix
+pixi run build-vscode
+```
+
+发布到 VSCode Marketplace（需要 `VSCE_PAT` 环境变量）：
+
+```shell
+pixi run publish-vscode
+```
+
+> [!TIP]
+> 若已编译 clice，本地调试时可在 VSCode 设置中填写 `clice.executable`，使扩展指向你的自定义构建。
+
+开发与调试：
+
+1. `pixi shell -e node`
+2. 在 `editors/vscode` 下运行 `pnpm run watch`（增量构建）
+3. VSCode 中使用 “Run Extension/Launch Extension” 调试配置，或执行 `code --extensionDevelopmentPath=$(pwd)/editors/vscode`
+
+常用脚本（在 `pixi shell -e node` 下）：
+
+```bash
+pnpm run package # 等价于 pixi run build-vscode
+pnpm run publish # 等价于 pixi run publish-vscode
+```
+
+如果不使用 pixi，请自行准备 node.js >= 20、pnpm，然后在 `editors/vscode` 目录执行：
+
+```bash
+pnpm install
+pnpm run package
+```
+
+## Neovim
+
+Neovim 插件位于 `editors/nvim`，使用 Lua 编写。目前功能仍在演进中。
+
+- 将仓库路径加入 `runtimepath`，例如：`set rtp+=/path/to/clice/editors/nvim`
+- 或在本地创建软链接：`~/.config/nvim/pack/clice/start/clice` -> `<repo>/editors/nvim`
+- 需要 `clice` 可执行文件可在 `$PATH` 中被找到
+
+开发提示：代码量较小，可直接在 Neovim 中加载并通过 `:messages`/LSP 日志观察效果；格式化可使用 `stylua`（仓库中已提供 `stylua.toml`）。
+
+## Zed
+
+Zed 插件位于 `editors/zed`，使用 Rust 和 `zed_extension_api`。
+
+建议的本地验证流程：
+
+```bash
+cd editors/zed
+cargo build --release
+```
+
+随后按 Zed 官方指南加载本地扩展（需安装 Zed CLI），在启动前确保 `clice` 已在 PATH 中。发布时同样遵循 Zed 扩展发布流程。

+你可以在 clice 中实现一个 server plugin 来扩展 clice 的功能。
+
+## 用例
+
+当你使用 `clice` 作为 LLM 代理的 LSP 后端时，比如 claude code，你可以添加插件来提供一些额外功能。
+
+## 编写插件
+
+当一个插件被服务器加载时，它会调用 `clice_get_server_plugin_info` 来获取关于这个插件的信息以及如何注册它的定制点。
+
+这个函数需要由插件实现，请参考下面的示例：
+
+```cpp
+extern "C" ::clice::PluginInfo LLVM_ATTRIBUTE_WEAK
+clice_get_server_plugin_info() {
+  return {
+    CLICE_PLUGIN_API_VERSION, "MyPlugin", "v0.1", CLICE_PLUGIN_DEF_HASH,
+    [](ServerPluginBuilder builder) {  ... }
+  };
+}
+```
+
+请参考 [PluginProtocol.h](/include/Server/PluginProtocol.h) 了解更多细节。
+
+## 编译插件
+
+插件必须使用与 clice 一致的依赖和编译器选项来编译，否则会导致 undefined behavior。[config/llvm-manifest.json](/config/llvm-manifest.json) 中定义了 clice 使用的构建信息。
+
+## 加载插件
+
+为了安全考虑，clice 不允许通过配置文件来加载插件，而必须通过命令行选项来指定插件的路径。
+
+在 `clice` 启动时，它会加载所有在命令行中指定的插件。你可以通过 `--plugin-path` 选项来指定插件的路径。
+
+```shell
+$ clice --plugin-path /path/to/my-plugin.so
+```
+
+## 获取 `CLICE_PLUGIN_DEF_HASH` 的内容
+
+在 `clice_get_server_plugin_info` 函数中需要返回两个值。
+
+- `CLICE_PLUGIN_API_VERSION` 用于确保插件和服务器之间的 `clice_get_server_plugin_info` 函数的一致性。
+- `CLICE_PLUGIN_DEF_HASH` 用于确保插件和服务器之间的 C++ 声明的一致性。
+
+要调试 `CLICE_PLUGIN_DEF_HASH` 的内容，你可以运行以下命令：
+
+```shell
+$ git clone https://github.com/clice-io/clice.git
+$ cd clice
+$ git checkout `clice --version --git-describe`
+$ python scripts/plugin-def.py content > /tmp/plugin-proto.h
+```
+
+你将会得到一个 C 源码格式的文件，内容大致如下：
+
+```cpp
+#if 0
+// begin of config/llvm-manifest.json
+[
+  {
+    "version": "21.1.4+r1",
+    "filename": "arm64-macos-clang-debug-asan.tar.xz",
+    "sha256": "7da4b7d63edefecaf11773e7e701c575140d1a07329bbbb038673b6ee4516ff5",

+    "asan": true,
+    "platform": "macosx",
+    "build_type": "Debug"
+  },
+  ...
+]
+...
+#endif
+```
+
+## Builtin libraries
