-# Publish your first datatoken
+# Quickstart: Publish datatoken
 
-## A. Set Ethereum network & node (Rinkeby & Infura)
+## Run the services
 
-1.  Infura runs hosted Ethereum nodes. Go to https://infura.io and sign up
+In a new console:
 
-2.  At Infura site, create a new project
-
-3.  Within the project settings page, note your Infura `project id` value. We will use it in the next step.
-
-4.  Make the network available as an envvar. In console:
-
-<!---->
-
-    export NETWORK_URL=https://rinkeby.infura.io/v3/<your Infura project id>
-
-## B. Set Ethereum account and get Rinkeby ETH
-
-1.  [Install Metamask to your browser](https://docs.oceanprotocol.com/tutorials/metamask-setup/). This will generate an Ethereum account for you.
-
-2.  [Export the private key from Metamask](https://metamask.zendesk.com/hc/en-us/articles/360015289632-How-to-Export-an-Account-Private-Key). Write it down.
-
-3.  [Get Rinkeby ETH from a faucet](https://faucet.rinkeby.io/). Have it sent to  the your Metamask's Ethereum account address.
+```console
+#grab repo
+git clone https://github.com/oceanprotocol/barge
+cd barge
 
-4.  Make your private key available as an envvar. In console:
+#clean up old containers (to be sure)
+docker system prune -a --volumes
 
-<!---->
+#run barge (runs ganache, Provider, Aquarius)
+./start_ocean.sh  --with-provider2
+```
 
-    export MY_TEST_KEY=<my_private_key>
+## Create config file
+Create a file called `config.ini` and fill it as follows.
+```text
+[eth-network]
+network = ganache
+artifacts.path = ~/.ocean/ocean-contracts/artifacts
+address.file = ~/.ocean/ocean-contracts/artifacts/address.json
+```
 
-## C. Install ocean-lib
+## Install the library, set envvars
 
-In bash console:
+In a new console:
 
 ```console
-#create a python virtualenv
+#Initialize virtual environment and activate it.
 python -m venv venv
-source venv/bin/activate 
+source venv/bin/activate
 
-#install!
+#Install the ocean.py library
 pip install ocean-lib
+
+#set envvars
+export TEST_PRIVATE_KEY1=0xc594c6e5def4bab63ac29eed19a134c130388f74f019bc74b8f4389df2837a58
+
+#go into python
+python
 ```
 
-## D. Publish datatokens
+## Publish datatokens
 
-In Python console:
+In the Python console:
 
 ```python
 import os
+from ocean_lib.config import Config
 from ocean_lib.ocean.ocean import Ocean
 from ocean_lib.web3_internal.wallet import Wallet
 
-private_key = os.getenv('MY_TEST_KEY')
-config = {'network': os.getenv('NETWORK_URL')}
+private_key = os.getenv('TEST_PRIVATE_KEY1')
+config = Config('config.ini')
 ocean = Ocean(config)
 
 print("create wallet: begin")
 wallet = Wallet(ocean.web3, private_key=private_key)
 print(f"create wallet: done. Its address is {wallet.address}")
 
-print("create datatoken: begin. This will take a few seconds, since it's a transaction on Rinkeby.")
+print("create datatoken: begin.")
 datatoken = ocean.create_data_token("Dataset name", "dtsymbol", from_wallet=wallet) 
 print(f"created datatoken: done. Its address is {datatoken.address}")
 ```

-If you made it to the end: congrats, you have created your first Ocean datatoken! 🐋
-
-Or, if you got an error like "insufficient funds for gas", it's because your account doesn't have enough ETH to pay for gas. Get more from the faucet linked above.
-
-Follow-on tutorials will flesh things out more.
