+
+
+
+# Introduction
+
+[Parachain-launch](https://github.com/open-web3-stack/parachain-launch) is a script that generates a docker compose file allowing you to launch a testnet of multiple blockchain nodes.
+
+To generate the compose file, first ensure `parachain-launch` is installed and run the following command
+
+```
+parachain-launch generate statemine.yml
+```
+
+This will produce an output directory that contains all the necessary files to run the testnet.
+
+Once the run is successful, you can spin up the infrastructure using the below command
+
+```
+docker-compose -f output/docker-compose.yml up -d
+```
+
+# Requirements
+[docker-compose](https://docs.docker.com/compose/install/) and [Parachain-launch](https://github.com/open-web3-stack/parachain-launch)
