[_Spree_](https://docs.oceanprotocol.com/concepts/testnets/#a-spree-testnet-for-local-development), a local Ocean test network, can be used instead of remotely connecting to Nile. For this you first have to get up the Spree network by using [oceanprotocol/barge](https://github.com/oceanprotocol/barge).
### Run Spree with Barge
Clone the barge repository and use its startup script:

Note that compiling and deploying the contracts in your local Docker network takes some time so it can take a few minutes until the network is ready to be interacted with. That usually is the case once `keeper-contracts_1` container doesn't show any messages anymore.
### Copy Contract Artifacts
At the end of the contract compiling and deploying you need to copy the resulting _Spree_ contract artifacts from the Docker container to your local `@oceanprotocol/keeper-contracts` dependency folder. The _keeper-contracts_ Docker container will output all artifacts in a hidden folder in your home folder so you can copy from there:
```bash
cp ~/.ocean/keeper-contracts/artifacts/* ./node_modules/@oceanprotocol/keeper-contracts/artifacts/
```
### Get Spree Ether
You will also need some [_Spree_ Ether](/tutorials/get-ether-and-ocean-tokens/#get-ether-for-a-local-spree-testnet) in your MetaMask account. You can execute this, replacing `<YOUR ADDRESS>` with your MetaMask account address:
```bash
curl --data '{"address": "<YOUR ADDRESS>", "agent": "curl"}' -H "Content-Type: application/json" -X POST http://localhost:3001/faucet
```
### Adjust App Config
Finally, move back to your marketplace React app and modify the Ocean instance config in `src/index.js` to use the Spree endpoints:
