-## bRPC 作为Bazel第三方依赖
-1. bRPC 依赖于一些开源库, 但这些库并没有提供bazel支持, 所以需要你手动将一部分依赖加入到你的构建项目中.

+## bRPC 作为 Bazel 第三方依赖
+
+推荐在 Bazel 项目中使用 bzlmod（`MODULE.bazel`）依赖本地 bRPC 源码。
+`example/build_with_bazel_module` 中有一个可运行的示例。
+
+先在你的 `.bazelrc` 中添加 bRPC 使用的 registry：
+
+```shell
+common --registry=https://bcr.bazel.build
+common --registry=https://baidu.github.io/babylon/registry
+common --registry=https://raw.githubusercontent.com/apache/brpc/master/registry
+```
+
+然后在 `MODULE.bazel` 中添加 bRPC，并指向本地 bRPC 源码：
+
+```python
+module(
+    name = "my_brpc_app",
+    version = "0.1.0",
+)
+
+bazel_dep(name = "protobuf", version = "27.3", repo_name = "com_google_protobuf")
+bazel_dep(name = "brpc", version = "1.17.0", repo_name = "apache_brpc")
+
+local_path_override(
+    module_name = "brpc",
+    path = "/path/to/brpc",
+)
+```
+
+`bazel_dep` 用来声明模块名和仓库映射，`local_path_override` 让 Bazel 使用本地源码，而不是从 registry 解析 bRPC。
+
+之后在目标中链接 bRPC：
+
+```python
+cc_binary(
+    name = "server",
+    srcs = ["server.cpp"],
+    deps = [
+        "@apache_brpc//:brpc",
+    ],
+)
 ```
-内容添加到你的WORKSPACE中.
 
-3. 链接请使用
-  ```c++
-  ...
-  deps = [
+如果服务使用 protobuf，可以从 bRPC 加载 `brpc_proto_library`：
+
+```python
+load("@apache_brpc//bazel/tools:brpc_proto_library.bzl", "brpc_proto_library")
+
+brpc_proto_library(
+    name = "cc_echo_proto",
+    srcs = ["echo.proto"],
+)
+```
+
+## 旧版 WORKSPACE 用法
+
+仍在使用 `WORKSPACE` 的项目可以参考 `example/build_with_bazel`。
+
+1. 将 `example/build_with_bazel/*.BUILD` 和
+   `example/build_with_bazel/brpc_workspace.bzl` 移动到你的项目根目录下。
+2. 在 `WORKSPACE` 中添加：
+
+```python
+load("@//:brpc_workspace.bzl", "brpc_workspace")
+
+brpc_workspace()
+```
+
+3. 在目标中链接 `apache_brpc`：
+
+```python
+deps = [
     "@apache_brpc//:bthread",
     "@apache_brpc//:brpc",
     "@apache_brpc//:butil",
     "@apache_brpc//:bvar",

+### 使用bazel编译brpc
+
+brpc也可以直接使用[Bazel](https://bazel.build)编译，不需要先执行`config_brpc.sh`。推荐使用Bazelisk或`.bazelversion`中固定的Bazel版本（`7.2.1`），这是当前仓库默认验证的版本。bzlmod（`MODULE.bazel`）构建会拉取其中声明的第三方库，例如protobuf、gflags、leveldb、openssl，但仍需要可用的C++工具链和平台SDK。Bazel构建已在Linux CI中覆盖，brpc库目标也在macOS CI中覆盖。
+
+克隆brpc并进入项目目录：
+```shell
+$ git clone https://github.com/apache/brpc.git
+$ cd brpc
+```
+
+然后编译brpc库：
+```shell
+$ bazel build -- //:brpc
+```
+
+如果需要一并编译样例：
+```shell
+$ bazel build -- //:brpc //example/...
+```
+
+修改编译器为clang，添加选项`--action_env=CC=clang --action_env=CXX=clang++`。
+
+可选功能通过`--define`开启，例如`--define with_glog=true`、`--define with_thrift=true`、`--define with_bthread_tracer=true`、`--define with_debug_lock=true`。完整的`--define`选项列表见`bazel/config/BUILD.bazel`。
+
+**用bazel运行样例**
+
+```shell
+$ bazel run //example:echo_c++_server &
+$ bazel run //example:echo_c++_client
+```
+
+**用bazel运行测试**
+
+```shell
+$ bazel test //test/...
+```
+
+**在自己的项目中把brpc作为bazel依赖**
+
+参考[Bazel Support](bazel_support.md)了解如何在其他Bazel项目中依赖brpc，`example/build_with_bazel_module`中有一个可运行的bzlmod样例。

 ## bRPC as a Bazel third-party dependency
-1. bRPC relies on a number of open source libraries that do not provide bazel support, so you will need to manually add some of these dependencies to your build project.
-2. Move the BUILD file /example/build_with_bazel/*.BUILD and brpc_workspace.bzl to the root of your project, and add the contents of 
-```c++
-    load("@//:brpc_workspace.bzl", "brpc_workspace")
-    brpc_workspace();
+
+The recommended way to depend on a local bRPC checkout from a Bazel project is
+to use bzlmod (`MODULE.bazel`). See `example/build_with_bazel_module` for a
+runnable example.
+
+Add the registries used by bRPC to your `.bazelrc`:
+
+```shell
+common --registry=https://bcr.bazel.build
+common --registry=https://baidu.github.io/babylon/registry
+common --registry=https://raw.githubusercontent.com/apache/brpc/master/registry
+```
+
+Add bRPC to your `MODULE.bazel`, and point it to your local bRPC checkout:
+
+```python
+module(
+    name = "my_brpc_app",
+    version = "0.1.0",
+)
+
+bazel_dep(name = "protobuf", version = "27.3", repo_name = "com_google_protobuf")
+bazel_dep(name = "brpc", version = "1.17.0", repo_name = "apache_brpc")
+
+local_path_override(
+    module_name = "brpc",
+    path = "/path/to/brpc",
+)
+```
+
+The `bazel_dep` keeps the module name and repository mapping, while
+`local_path_override` makes Bazel use the local checkout instead of resolving
+bRPC from a registry.
+
+Then link bRPC from your targets:
+
+```python
+cc_binary(
+    name = "server",
+    srcs = ["server.cpp"],
+    deps = [
+        "@apache_brpc//:brpc",
+    ],
+)
 ```
-to your WORKSPACE
 
-3. link apache_brpc like:
-  ```c++
-  ...
-  deps = [
+If your service uses protobuf, load `brpc_proto_library` from bRPC:
+
+```python
+load("@apache_brpc//bazel/tools:brpc_proto_library.bzl", "brpc_proto_library")
+
+brpc_proto_library(
+    name = "cc_echo_proto",
+    srcs = ["echo.proto"],
+)
+```
+
+## Legacy WORKSPACE usage
+
+For projects that still use `WORKSPACE`, see `example/build_with_bazel`.
+
+1. Move `example/build_with_bazel/*.BUILD` and
+   `example/build_with_bazel/brpc_workspace.bzl` to the root of your project.
+2. Add the following to your `WORKSPACE`:
+
+```python
+load("@//:brpc_workspace.bzl", "brpc_workspace")

+brpc_workspace()

+### Compile brpc with bazel
+
+brpc can also be built directly with [Bazel](https://bazel.build) without running `config_brpc.sh` first. Use Bazelisk or the Bazel version pinned in `.bazelversion` (`7.2.1`), which is the default version validated by this repository. The bzlmod (`MODULE.bazel`) build fetches the third-party libraries declared there, such as protobuf, gflags, leveldb, and openssl, but you still need a working C++ toolchain and platform SDK. Bazel builds are covered by Linux CI; the brpc library target is also covered by macOS CI.
+
+Clone brpc, cd into the repo and run:
+```shell
+$ git clone https://github.com/apache/brpc.git
+$ cd brpc
+```
+
+Then build the brpc library:
+```shell
+$ bazel build -- //:brpc
+```
+
+To also build the examples:
+```shell
+$ bazel build -- //:brpc //example/...
+```
+
+To change compiler to clang, add `--action_env=CC=clang --action_env=CXX=clang++`.
+
+Optional features are toggled with `--define`, e.g. `--define with_glog=true`, `--define with_thrift=true`, `--define with_bthread_tracer=true`, `--define with_debug_lock=true`. See `bazel/config/BUILD.bazel` for the full list of `--define` switches.
+
+**Run example with bazel**
+
+```shell
+$ bazel run //example:echo_c++_server &
+$ bazel run //example:echo_c++_client
+```
+
+**Run tests with bazel**
+
+```shell
+$ bazel test //test/...

+
+**Use brpc as a bazel dependency in your own project**

+See [Bazel Support](bazel_support.md) for how to depend on brpc from another Bazel project, and `example/build_with_bazel_module` for a runnable bzlmod example.
