+## 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.
+2. 将 /example/build_with_bazel/*.BUILD 和 brpc_workspace.bzl 该文件移动到你的项目根目录下, 将
+```c++
+    load("@//:brpc_workspace.bzl", "brpc_workspace")
+    brpc_workspace();
+```
+内容添加到你的WORKSPACE中.
+
+3. 链接请使用
+  ```c++
+  ...
+  deps = [
+    "@apache_brpc//:bthread",
+    "@apache_brpc//:brpc",
+    "@apache_brpc//:butil",
+    "@apache_brpc//:bvar",
+  ]

+## 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();
+```
+to your WORKSPACE
+
+3. link apache_brpc like:
+  ```c++
+  ...
+  deps = [
+    "@apache_brpc//:bthread",
+    "@apache_brpc//:brpc",
+    "@apache_brpc//:butil",
+    "@apache_brpc//:bvar",
+  ]
+  ...
