 ## 2. Alice hosts the dataset
 
-A locally providerService is required, which will serve just one file for this demo.
-Let's create the file to be shared:
-```
-touch /var/mydata/myFolder1/file
-````
-
-Run the providerService:
-(given that ERC20 contract address from the above is 0x1234)
+Clone [provider-py](https://github.com/oceanprotocol/provider-py) and update your local environment variables:
 
 ```
-ENV DT="{'0x1234':'/var/mydata/myFolder1'}"
-docker run @oceanprotocol/provider-py -e CONFIG=DT
+export PROVIDER_ADDRESS=your_provider_address
+export PROVIDER_KEY=your_provider_key
