# Zombienet configuration Zombienet aims to be a testing framework for Substrate based blockchains, providing a simple cli tool that allows users to spawn and test ephemeral networks. ## Start a development chain Firstly build Polkadot binaries with: ```sh $ scripts/zombienet.sh build ``` This process can take some time, so please be patient. If on Linux, you can alternatively download the binaries to speed up the process with: ```shell $ scripts/zombinet.sh init ``` Once Polkadot binaries are in place you can spawn a local testnet by running the following command: ```shell $ scripts/zombienet.sh devnet ```
