 ## Install Connector
 
+First, you need to install the `taospy` module. Run the command below in your terminal.
+
+```
+pip3 install taospy
+```
+
+You'll need to have Python3 installed.
+
 ## Config
 
+Run this command in your terminal to save connect parameters as environment variables:
+
+```
+export TDENGINE_CLOUD_HOST=<host>
+export TDENGINE_CLOUD_PORT=<port>
+export TDENGINE_CLOUD_TOKEN=<token>
+export TDENGINE_USER_NAME=<username>
+export TDENGINE_PASSWORD=<password>
+```
+
+
+<!-- exclude -->
+:::note
+You should replace above placeholders as real values. To get these values, please log in TDengine Cloud and switch to "Connector" section.
+
+:::
+<!-- exclude-end -->
+
 ## Connect
 
+```python
+import taosrest
+import os
+
+host = os.environ["TDENGINE_CLOUD_HOST"]
+port = os.environ["TDENGINE_CLOUD_PORT"]
+token = os.environ["TDENGINE_CLOUD_TOKEN"]
+user = os.environ["TDENGINE_USER_NAME"]
+password = os.environ["TDENGINE_PASSWORD"]
+
+conn = taosrest.connect(host=host,
