+## Fallback contract support
+
+In order to better support content resolution on different service providers (such as Swarm and IPFS), [EIP-1577](https://eips.ethereum.org/EIPS/eip-1577)
+was introduced and with it changes that allow applications to know _where_ content hashes are stored (i.e. if the
+requested hash resides on Swarm or IPFS).
+
+The code under `contracts/ens/contract` reflects the new Public Resolver changes and the code under `fallback_contract` allows
+us to support the old contract resolution in cases where the ENS name owner did not update her Resolver contract, until the migration
+period ends (date arbitrarily set to June 1st, 2019).
