+2. Use `bin/spc doctor --auto-fix` and then build for glibc directly. 
 ([Related source code](https://github.com/crazywhalecc/static-php-cli/blob/main/src/SPC/doctor/item/LinuxMuslCheck.php))
 
-Generally speaking, the build results in these two environments are consistent, and you can choose according to actual needs.
-
-In the doctor module, static-php-cli will first detect the current Linux distribution. 
-If the current distribution is a glibc environment, you will be prompted to install the musl-wrapper and musl-cross-make packages.
-
-The process of installing `musl-wrapper` in the glibc environment is as follows:
-
-1. Download the specific version of [musl-wrapper source code](https://musl.libc.org/releases/) from the musl official website.
-2. Use `gcc` installed from the package management to compile the musl-wrapper source code and generate `musl-libc` and other libraries: `./configure --disable-gcc-wrapper && make -j && sudo make install`.
-3. The musl-wrapper related libraries will be installed in the `/usr/local/musl` directory.
-
-The process of installing `musl-cross-make` in the glibc environment is as follows:
-
-1. Download the precompiled [musl-cross-make](https://dl.static-php.dev/static-php-cli/deps/musl-toolchain/) compressed package from dl.static-php.dev .
-2. Unzip to the `/usr/local/musl` directory.
-
-::: tip
-In the glibc environment, static compilation can be achieved by directly installing musl-wrapper, 
-but musl-wrapper only contains `musl-gcc` and not `musl-g++`, which means that C++ code cannot be compiled.
-So we need musl-cross-make to provide `musl-g++`.
-
-The reason why the musl-cross-make package cannot be compiled directly locally is that 
-its compilation environment requirements are relatively high (requires more than 36GB of memory, compiled under Alpine Linux), 
-so we provide precompiled binary packages that can be used for all Linux distributions.
-
-At the same time, the package management of some distributions provides musl-wrapper, 
-but musl-cross-make needs to match the corresponding musl-wrapper version, 
-so we do not use package management to install musl-wrapper.
-
-Compiling musl-cross-make will be introduced in the **musl-cross-make Toolchain Compilation** section of this chapter.

 ### Docker Environment

+The Docker environment refers to using Docker containers to build static PHP. You can use `bin/spc-alpine-docker` or `bin/spc-gnu-docker` to build.
+Before executing this command, you need to install Docker first.
 
 After executing `bin/spc-alpine-docker`, static-php-cli will automatically download the Alpine Linux image and then build a `cwcc-spc-x86_64` or `cwcc-spc-aarch64` image.
 Then all build process is performed within this image, which is equivalent to compiling in Alpine Linux.
 
-## musl-cross-make Toolchain Compilation
-
-In Linux, although you do not need to manually compile the musl-cross-make tool, 
-if you want to understand its compilation process, you can refer here.
-Another important reason is that this may not be compiled using automated tools such as CI and Actions, 
-because the existing CI service compilation environment does not meet the compilation requirements of musl-cross-make, 
-and the configuration that meets the requirements is too expensive.
-
-The compilation process of musl-cross-make is as follows:
-
-Prepare an Alpine Linux environment (either directly installed or using Docker). 
-The compilation process requires more than **36GB** of memory, 
-so you need to compile on a machine with larger memory. 
-Without this much memory, compilation may fail.
-
-Then write the following content into the `config.mak` file:
-
-```makefile
-STAT = -static --static
-FLAG = -g0 -Os -Wno-error
-
-ifneq ($(NATIVE),)
-COMMON_CONFIG += CC="$(HOST)-gcc ${STAT}" CXX="$(HOST)-g++ ${STAT}"

-2. 使用 `bin/spc doctor` 安装 musl-wrapper 和 musl-cross-make 套件，然后直接正常构建。（[相关源码](https://github.com/crazywhalecc/static-php-cli/blob/main/src/SPC/doctor/item/LinuxMuslCheck.php)）
-
-一般来说，这两种构建方式的构建结果是一致的，你可以根据实际需求选择。
-
-在 doctor 模块中，static-php-cli 会先检测当前的 Linux 发行版。如果当前发行版是 glibc 环境，会提示需要安装 musl-wrapper 和 musl-cross-make 套件。
-
-在 glibc 环境下安装 musl-wrapper 的过程如下：
-
-1. 从 musl 官网下载特定版本的 [musl-wrapper 源码](https://musl.libc.org/releases/)。
-2. 使用从包管理安装的 `gcc` 编译 musl-wrapper 源码，生成 `musl-libc` 等库：`./configure --disable-gcc-wrapper && make -j && sudo make install`。

-::: tip
-在 glibc 环境下，静态编译可以通过直接安装 musl-wrapper 来实现，但是 musl-wrapper 仅包含了 `musl-gcc`，而没有 `musl-g++`，这也就意味着无法编译 C++ 代码。
-所以我们需要 musl-cross-make 来提供 `musl-g++`。
-
-而 musl-cross-make 套件无法在本地直接编译的原因是它的编译环境要求比较高（需要 36GB 以上内存，Alpine Linux 下编译），所以我们提供了预编译好的二进制包，可用于所有 Linux 发行版。
-
-同时，部分发行版的包管理提供了 musl-wrapper，但 musl-cross-make 需要匹配对应的 musl-wrapper 版本，所以我们不使用包管理安装 musl-wrapper。

+Docker 环境指的是使用 Docker 容器来构建静态 PHP，你可以使用 `bin/spc-alpine-docker` 或 `bin/spc-gnu-docker` 来构建。
 执行这个命令前需要先安装 Docker，然后在项目根目录执行 `bin/spc-alpine-docker` 即可。
 
 在执行 `bin/spc-alpine-docker` 后，static-php-cli 会自动下载 Alpine Linux 镜像，然后构建一个 `cwcc-spc-x86_64` 或 `cwcc-spc-aarch64` 的镜像。
 然后一切的构建都在这个镜像内进行，相当于在 Alpine Linux 内编译。总的来说，Docker 环境就是 musl 环境。
 
-## musl-cross-make 工具链编译
-
-在 Linux 中，尽管你不需要手动编译 musl-cross-make 工具，但是如果你想了解它的编译过程，可以参考这里。
-还有一个重要的原因就是，这个可能无法使用 CI、Actions 等自动化工具编译，因为现有的 CI 服务编译环境不满足 musl-cross-make 的编译要求，满足要求的配置价格太高。
-
-musl-cross-make 的编译过程如下：
-
-准备一个 Alpine Linux 环境（直接安装或使用 Docker 均可），编译的过程需要 36GB 以上内存，所以你需要在内存较大的机器上编译。如果没有这么多内存，可能会导致编译失败。
-
-然后将以下内容写入 `config.mak` 文件内：
-
-```makefile
