+I am not responsible for your actions using this software. Just because you can steal someones Ethereum doesn't mean you should.... Plus statistically you will never find an address with a balance.
+
+This software will forever check random Ethereum private keys for a balance. When one is found it will be emailed to you. Currently only Gmail as the sender is allowed, and you will have to allow unsecure apps in your google settings.
+
+Check docker-compose.sample.yml for configuration and environment options.  Found addresses and private keys will also be logged to /output/output.txt
