 ## Run Raiden
 
 You can start Raiden with either Geth, Parity or Infura as RPC Endpoint. All you need is an Ethereum Account and the respective keystore file funded with the tokens you want to transfer.

 Per default a **Pathfinding Service** is used by your Raiden client when a **mediated transfer** is initiated. The maximum amount paid for one request to the Pathfinding services is set to `0.05` RDN and 3 different paths are requested.

+## Testnet usage
+
+When using one of the Ethereum testnets, you have to set the `--environment-type` to development-mode,
+so that the correct Matrix federation network for the PFS will be chosen.
+
+In order to connect to one of the Ethereum testnets, you have to provide the following additional arguments:
+
+```console
+--network-id $TESTNET-NAME-OR-ID \
+--environment-type development 
+```
+
+E.g. for the Goerli testnet `$TESTNET-NAME-OR_ID` would be `goerli` or `5`.
+
+More information on how to aquire and deposit the utility token (SVT) on the testnets are [provided in the v1 docs](https://raiden-network.readthedocs.io/en/latest/overview_and_guide.html#depositing-tokens-to-pay-the-services).
