+## Weave 镜像使用帮助
+
+> Weave is a communications platform that includes the Weave Device SDK and the Weave Server to enable OEM manufactures to connect their devices to Google cloud services.
+
+简单说 Weave 是 Google 开发的物联网通讯平台。TUNA 同步该镜像代码的主要意义在于用于 [chromiumos](/help/chromiumos)的同步，继续看之前请确认你真的需要使用 [weave](https://developers.google.com/weave/) 的源代码。
+
+#### 准备工作
+
+下载 repo 工具:
+
+```bash
+mkdir ~/bin
+PATH=~/bin:$PATH
+curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
+chmod a+x ~/bin/repo
+```
+
+或者使用tuna的[git-repo镜像](https://mirrors.tuna.tsinghua.edu.cn/help/git-repo/)
+
+#### 下载代码
+
+建立工作目录:
+
+```
+mkdir WORKING_DIRECTORY
+cd WORKING_DIRECTORY
+```
+
+初始化仓库:
+
+```
+repo init -u https://mirrors.tuna.tsinghua.edu.cn/git/weave/weave/manifest
+```
+
+**注意: 本镜像是 Weave 的 master 分支的镜像，如果使用本镜像下载 Weave 的其他版本很大概率会失败**
+
+接着使用编辑器打开`.repo/manifests/default.xml`这个文件，将
+
+```
+"https://chromium.googlesource.come"
+```
+
+替换为
+
+```
+"https://mirrors.tuna.tsinghua.edu.cn/git/chromiumos/"
+```
+
+将
+
+```
+"https://android.googlesource.come"
+```
+
+替换为
+
+```
+"https://aosp.tuna.tsinghua.edu.cn/"
+```
+
+将
+
+```
+"https://weave.googlesource.come"
+```
+
+替换为
+
+```
+"https://mirrors.tuna.tsinghua.edu.cn/git/weave/"
+```
+
+并删除如下几行（这几行是非公开的repo，因此tuna并没有镜像）：
+
+```
+<project path="libuweave" name="weave/libuweave" />
+<project path="cocoapods" name="weave/cocoapods" />
+<project path="tests" name="weave/tests" />
+```
+
+即可。
+
+
+如果提示无法连接到 gerrit.googlesource.com，可以先运行如下指令：
+
+```
+export REPO_URL = 'https://mirrors.tuna.tsinghua.edu.cn/git/git-repo'
+```
+
+同步源码树（以后只需执行这条命令来同步）：
+
+```
+repo sync
+```
