+# InfluxDB v3 (alpha)
+
+This sample demonstrates how to deploy and use InfluxDB v3 as a time series database in your Quix Cloud pipeline. 
+
+Please note: this image is provided by Influx and is offered as-is, with no specific support from Quix. For any support, contact Influx directly.
+
+[!WARNING]
+This offering is currently in alpha and intended only for simple testing/validation, 
+especially since authentication is not set up. 
+Only local file storage is supported in this implementation.
+
+You can learn more about InfluxDB3 [from their documentation](https://docs.influxdata.com/influxdb3/core/).
+
+## How to Run
+
+1. Create an account or log in to your [Quix](https://portal.platform.quix.io/signup?xlink=github) account and navigate to the Code Samples section.
+2. Click `Deploy` to launch a pre-built container in Quix.
+3. Enable state, otherwise changes will be lost on restart. Please note, the necessary storage type may not be supported on all Quix Platforms.
+
+## How to Use
+To interact with InfluxDB v3 from your pipeline, either use one of the no-code [influxdb3 connectors](https://quix.io/integrations?category=Time+series+DB)
+in Quix Cloud or use a Quix Streams [InfluxDBSource](https://quix.io/docs/quix-streams/connectors/sources/influxdb3-source.html) or [InfluxDB3Sink](https://quix.io/docs/quix-streams/connectors/sinks/influxdb3-sink.html) directly.
+
+Use the following values to connect:
+```shell
+host="http://influxdb3"
+organization_id="<ANYTHING>"  # required, but not used
+token="<ANYTHING>"            # required, but not used
+```
