 3. 有些公司可能安装了加密软件，将对配置文件进行加密，将导致参数全部失效，此时可以修改安装目录下的 `./httpdist/dist/node.exe` 重命名为  `./httpdist/dist/chrome.exe`(策略允许) ,修改安装目录的 showKeyBoard.ini 文件，增加参数` serverExecName=./httpdist/dist/chrome.exe`
 4. 如果系统时间不正确，比如某一天的时间变成了N年后，可能导致之后的应用时长数据丢失，请运行安装目录的 fixStat修复统计数据.bat
 
+### 同步说明
+
+此处以 FreeFileSync 同步FTP举例
+
+1. 首先设定共享文件的保存目录，默认为安装目录下的 **share**
+2. 在 FreeFileSync 中配置本地share 和 FTP服务器双向同步，将同步文件生成为 ffs_batch文件，比如 Keyboard.ffs_batch
+3. 设定"**生成共享文件间隔小时数**" ,表示每隔多久将本地的记录打包
+4. 设置打包完成后自动执行的命令，如果安装了 FreeFileSync ,则可以直接执行 ffs_batch文件，比如命令可配置为上面的 Keyboard.ffs_batch
+5. 共享名默认为计算机名，可自行更改，将会在 历史和统计模块显示
+6. 系统每分钟会检查 共享文件目录的文件，解压到**dbs**目录中，如果有更新则会重新解压
+7. 在 历史和统计模块 可选择和查看本地解压后的其他设备的记录

 **Note**:
 1. Due to the use of system hooks, some computers may report viruses by mistake and need to be trusted.
-
 2. On some systems, you may need to run in administrator mode, otherwise showKeyBoard will not be able to listen to the keys
-
 3. Some companies may have installed encryption software, which will encrypt the configuration files, causing all parameters to become invalid. In this case, you can rename `./httpdist/dist/node.exe` in the installation directory to `./httpdist/dist/chrome.exe`, and modify the `showKeyBoard.ini` file in the installation directory by adding the parameter `serverExecName=./httpdist/dist/chrome.exe`.
-
 4. If the system time is incorrect, for example, the time of a certain day changes to N years later, it may lead to the loss of application usage duration data. Please run the `fixStat修复统计数据.bat` file in the installation directory. 
 
-   
+### Synchronization
+Here is an example of FreeFileSync synchronization FTP
+
+1. First set the directory where shared files are saved. The default directory is share in the installation directory
+2. Configure synchronization between local share and FTP server in FreeFileSync, and generate the synchronization file as ffs_batch file, such as Keyboard.ffs_batch
+3. Set the **Interval hours for generating shared files** to indicate how often local records are packaged
+4. Set the command to be automatically executed after packaging. If FreeFileSync is installed, you can directly execute the ffs_batch file. For example, the command can be configured as Keyboard.ffs_batch above
+5. The share name defaults to the computer name, which can be changed by itself and will be displayed in the history and statistics module
+6. The system will check the files in the shared file directory every minute and decompress them to the **dbs** directory. If there are updates, they will be decompressed again
+7. In the history and statistics module, you can select and view the records of other devices after local decompression
