-e.g., modify and compile with IDEA or Eclipse.
+Repository：https://github.com/apache/incubator-iotdb/tree/master
 
-Once all UTs are passed after you modify codes, your modification basically works!

+## Import IoTDB in IDE
+
+### IDEA
 
 * "File" -> "Open" -> choose the root path of IoTDB source code. 
 * use `mvn clean compile -Dmaven.test.skip=true`to get target.
 * mark directory ***server/target/generated-sources/antlr4*** as source code
 * mark directory ***service-rpc/target/generated-sources/thrift*** as source code 
 
-## Eclipse
+### Eclipse
 
 Using Eclipse to develop IoTDB is also simple but requires some plugins of Eclipse.
 
@@ -55,11 +90,24 @@ After the command is done, you can import IoTDB as an existing project:
 - If your Eclipse version is fashion enough (e.g., you are using the latest version of Eclipse),
 you can just choose menu "import" -> "Maven" -> "Existing Maven Projects".
  
+
 ## Debugging IoTDB
+
 The main class of IoTDB server is `org.apache.iotdb.db.service.IoTDB`.
 The main class of IoTDB cli is `org.apache.iotdb.client.Client` 
 (or `org.apache.iotdb.client.WinClient` on Win OS).
 
+The client needs parameter: "-h 127.0.0.1 -p 6667 -u root -pw root"
+
 You can run/debug IoTDB by using the two classes as the entrance.
 
 Another way to understand IoTDB is to read and try Unit Tests.
+
+* The implementation of RPC in the server ```server/src/main/java/org/apache/iotdb/db/service/TSServiceImpl```
+	* JDBC.execute() -> TSServiceImpl.executeStatement(TSExecuteStatementReq req)
+	* JDBC.executeQuery() -> TSServiceImpl.executeQueryStatement(TSExecuteStatementReq req)	
+	* Session.insert() -> TSServiceImpl.insert(TSInsertReq req)
+
+* Storage Engine: org.apache.iotdb.db.engine.StorageEngine
+* Query Engine: org.apache.iotdb.db.qp.Planner

 To make this manual more practical, we will use a specific scenario example to illustrate how to operate IoTDB databases at all stages of use. See [this page](https://github.com/apache/incubator-iotdb/blob/master/docs/Documentation/OtherMaterial-Sample%20Data.txt) for a look. For convenience, we also provide you with a sample data file in real scenario to import into the IoTDB system for trial and operation.

-According to the data attribute layers described in [sample data](https://raw.githubusercontent.com/apache/incubator-iotdb/master/docs/Documentation/OtherMaterial-Sample%20Data.txt), we can express it as an attribute hierarchy structure based on the coverage of attributes and the subordinate relationship between them, as shown in Figure 2.1 below. Its hierarchical relationship is: power group layer - power plant layer - device layer - sensor layer. ROOT is the root node, and each node of sensor layer is called a leaf node. In the process of using IoTDB, you can directly connect the attributes on the path from ROOT node to each leaf node with ".", thus forming the name of a timeseries in IoTDB. For example, The left-most path in Figure 2.1 can generate a timeseries named `ROOT.ln.wf01.wt01.status`.

+### Intellij idea
 
 推荐使用 Intellij idea。```mvn clean package -DskipTests``` 之后把 ```server/target/generated-sources/antlr4``` 和 ```service-rpc/target/generated-sources/thrift``` 标记为 ```Source Root```。 
 
+### Eclipse
+
+如果是 eclipse 2019 之前的版本，需要现在 IoTDB 根目录执行 `mvn eclipse:eclipse -DskipTests`。

+
+import -> Maven -> Existing Maven Projects
+
+## 调试代码

 * 服务器主函数：```server/src/main/java/org/apache/iotdb/db/service/IoTDB```，可以debug模式启动
 * 客户端：```client/src/main/java/org/apache/iotdb/client/```，linux 用 Clinet，windows 用 WinClint，可以直接启动，需要参数"-h 127.0.0.1 -p 6667 -u root -pw root"
 * 服务器的 rpc 实现（主要用来客户端和服务器通信，一般在这里开始打断点）：```server/src/main/java/org/apache/iotdb/db/service/TSServiceImpl```
