+### 修改默认配置
+
+`backend/src/main/resources/application.properties` 包括用户、项目、数据库等配置，可以通过修改配置定制服务：
+
+* **SPACE_HOME:** 存放 workspace 的目录，默认为 ${"user.home"}/.workspace  
+* **server.port:** 应用启动的端口  
+* **USERNAME:** 用户名，git 提交时会使用该值作为 user.name，默认为 coding。
+* **EMAIL:** 用户邮箱，git 提交时会使用该值作为 user.email，默认为 coding@coding.net  
+* **AVATAR:** 用户头像
+* **CODING_IDE_HOME:** 应用数据存放目录
+
+修改配置后，需要重启应用。另外如果修改了 `USERNAME`、`EMAIL` 的值，会在创建新的 Workspace 时生效。

+### Configurations
+
+`backend/src/main/resources/application.properties` contains configurations of user, project, database, etc., you can change these parameters to meet your need:
+
+* **SPACE_HOME:** path to your workspace directory, default to `${"user.home"}/.workspace`
+* **server.port:** backend server port
+* **USERNAME:** username, used by git as its `user.name` config when commit, defaults to "coding"
+* **EMAIL:** email, used by git as its `user.email` config when commit, defaults to "coding@coding.net"
+* **AVATAR:** user's avatar
+* **CODING_IDE_HOME:** path to store WebIDE application's data
+
+If changed, restart the application to let your configurations take effect. Note that changes on `USERNAME`, `EMAIL` *WILL NOT* apply to workspaces that are already created.
