+
+The Ethereum Virtual Machine (EVM) as a library, `libevm` is a fork of [`geth`](https://github.com/ethereum/go-ethereum) with
+injectable configuration directives. Although designed to support the Avalanche [C-Chain](https://github.com/ava-labs/coreth) and
+[EVM-L1s](https://github.com/ava-labs/subnet-evm) (formerly _subnets_), configuration is general-purpose and backwards-compatible
+with `geth`.
+
+
+We are immensely grateful for the hard work of the `geth` authors, and hope that our contribution can be of value to others too. Thank you!
