+
+In this section we will explain how to write into TDengine cloud service using REST API or schemaless protocols over REST interface.
+
+## REST API
+
+### Config
+
+Run this command in your terminal to save the TDengine cloud token and URL as variables:
+
+<Tabs defaultValue="bash">
+<TabItem value="bash" label="Bash">
+
+```bash
+export TDENGINE_CLOUD_TOKEN="<token>"
+export TDENGINE_CLOUD_URL="<url>"
+```
+
+</TabItem>
+<TabItem value="cmd" label="CMD">
+
+```bash
+set TDENGINE_CLOUD_TOKEN="<token>"
+set TDENGINE_CLOUD_URL="<url>"
+```
+
+</TabItem>
+<TabItem value="powershell" label="Powershell">
+
+```powershell
+$env:TDENGINE_CLOUD_TOKEN="<token>"
+$env:TDENGINE_CLOUD_URL="<url>"
+```
+
+</TabItem>
+</Tabs>
+
+### Insert Data using REST API
+
+Following command below show how to insert data into the table `d1001` of the database `test` via the command line utility `curl`.
+
+```bash
+curl -L \
+  -d "INSERT INTO d1001 VALUES (1538548685000, 10.3, 219, 0.31)" \
+  $TDENGINE_CLOUD_URL/rest/sql/test?token=$TDENGINE_CLOUD_TOKEN
+```
+
+## Schemaless
+
+### InfluxDB Line Protocol
+
+You can use any client that supports the http protocol to access the RESTful interface address `<cloud_url>/influxdb/v1/write` to write data in InfluxDB compatible format to TDengine. The EndPoint is as follows:
+
+```text
+/influxdb/v1/write?db=<db_name>&token=<cloud_token>
+```
+
+Support InfluxDB query parameters as follows.
+
+- `db` Specifies the database name used by TDengine
+- `precision` The time precision used by TDengine
+
+Note: InfluxDB token authorization is not supported at present. Only Basic authorization and query parameter validation are supported.
+
+### OpenTSDB Json and Telnet Protocol
+
+You can use any client that supports the http protocol to access the RESTful interface address `<cloud_url>/opentsdb/v1/put` to write data in OpenTSDB compatible format to TDengine. The EndPoint is as follows:
+
+```text
+/opentsdb/v1/put/json/<db>?token=<cloud_token>
+/opentsdb/v1/put/telnet/<db>?token=<cloud_token>
+```

+## Jupyter
+
+**Step 1: Install**
+
+For the users who are familiar with Jupyter to program in Python, both TDengine Python connector and Jupyter need to be ready in your environment. If you have not done yet, please use the commands below to install them.
+
+<Tabs defaultValue="pip" groupID="package">
+<TabItem value="pip" label="pip">
+
+```bash
+pip install jupyterlab
+pip3 install -U taospy

+<TabItem value="conda" label="conda">
+
+```
+conda install -c conda-forge jupyterlab
+conda install -c conda-forge taospy
+```
+
+</TabItem>
+</Tabs>
+
+**Step 2: Configure**
+
+In order for Jupyter to connect to TDengine cloud service, before launching Jupypter, the environment setting must be performed. We use Linux bash as example.
+
+```bash
+export TDENGINE_CLOUD_TOKEN="<token>"
+export TDENGINE_CLOUD_URL="<url>"
+jupyter lab
+```
+
+**Step 3: Connect**
+
+Once jupyter lab is launched, Jupyter lab service is automatically connected and shown in your browser. You can create a new notebook and copy the sample code below and run it.
+
+```python
+{{#include docs/examples/python/develop_tutorial.py:connect}}
