+This directory contains the IoTDB Handler as a Node.js application. As [Apache IoTDB](https://iotdb.apache.org/) is a time-series database, the IoTDB Handler connects to an existing IoTDB instance using the Thrift protocol. The handler utilizes the [IoTDB Thrift API](https://github.com/apache/thrift) to communicate with the database and perform operations. Configuration details, such as the IoTDB host, port, user credentials, and time zone, are specified in the handler's configuration file. The IoTDB Handler is designed to manage sessions, execute queries, and interact with the IoTDB instance efficiently during runtime.
+
+# Features
+
+- **Authentication**: Authenticates with IoTDB using the IoTDB host, port, user credentials, and time zone.
+- **Error Handling**: Logs and handles errors during database operations and synchronization.
+
+# Installation
+
+Execute within `iotdb` directory
+
+```bash
+npm install
+```
+
+# Configure IoTDB
+
+Before the Database-Router can start the IoTDB Handler without any errors you need to start and run Docker containers defined in a [Docker Compose file](/docker/).
+
+## Configure of a IoTDB Handler
+
+Create `config/config.js` with the following format, replacing the app id and the api key with yours.
+
+```js
+module.exports = {
+  iotdbHost: "your-iotdb-host", // Default "localhost"
+  iotdbPort: 6667, // Set this to the appropriate IotDB Port
+  iotdbUser: "your-iotdb-user", // Default "root"
+  iotdbPassword: "your-iotdb-password", // Default "root"
+  timeZone: "UTC+2", // Set this to the appropriate time zone
+};
+```
+
+> **_IMPORTANT:_** Do not commit this file to github!
+
+## Starting the IoTDB handler
+
+You do not need to start IotDB Handler manually. It is started by the DB-Router like described [here](../../router/README.md#Run).
