 # Connect Your rippled to a Parallel Network
 
-Ripple hosts [alternative test and development networks](parallel-networks.html) for developers to test their apps on the latest non-production version of the XRP Ledger (Testnet) or to test and experiment with features on the latest beta version (Devnet). **The funds used on these networks are not real funds and are intended for testing only.** You can connect your [`rippled` server](the-rippled-server.html) to either the Testnet or Devnet.
+Various [alternative test and development networks](parallel-networks.html) exist for developers to test their apps or experiment with features without risking real money. **The funds used on these networks are not real funds and are intended for testing only.** You can connect your [`rippled` server](the-rippled-server.html) to any of these test networks.
 
-**Caution:** The Devnet frequently has new and experimental [amendments](amendments.html) enabled, so the latest production release version is likely to be amendment blocked when connecting to Devnet. You should use a pre-release or nightly build when connecting to Devnet.
+**Caution:** On test networks with new and experimental features, you may need to run a pre-production release of the server to sync with the network. See the [Parallel Networks Page](parallel-networks.html) for information on what code version each network needs.
