+## Purpose of the golos.memo smart contract
+
+The `golos.memo` smart contract provides a storage for the memo-keys of the users. These keys can be used in client application to encrypt the private messaging between users. At the moment, the contract does not allow to add or remove memo keys, but only provides storage of memo keys that are imported from the genesis, for possible usage in the future.
+
+## Actions used in golos.memo smart contract
+
+The `golos.memo` smart contract does not support any actions.
