# Publish a Dataset 📤

Once you've configured the RPC environment variable, you're ready to publish a new dataset on the connected network. The flexible setup allows you to switch to a different network simply by substituting the RPC endpoint with one corresponding to another network. 🌐

To initiate the dataset publishing process, we'll start by updating the helper [DDO](../ddo-specification.md)(Decentralized Data Object) example named "SimpleDownloadDataset.json." This example can be found in the `./metadata` folder, located at the root directory of the cloned Ocean CLI project.

        }
    }
}
```

{% hint style="info" %}
The provided example creates a consumable asset with a predetermined price of 2 OCEAN. If you wish to modify this and create an asset that is freely accessible, you can do so by replacing the value of "stats.price.value" with 0 in the JSON example mentioned above.
{% endhint %}

Now, let's run the command to publish the dataset:

```bash
npm run cli publish metadata/simpleDownloadDataset.json
```

Executing this command will initiate the dataset publishing process, making your dataset accessible and discoverable on the Ocean Protocol network. 🌊
