 These contracts work together to enable native ETH restaking:
-* Users deploy `EigenPods` via the `EigenPodManager`, which contain beacon chain state proof logic used to verify a validator's withdrawal credentials, balance, and exit. An `EigenPod's` main role is to serve as the withdrawal address for one or more of a user's validators.
+* Users deploy `EigenPods` via the `EigenPodManager`, which contain beacon chain state proof logic used to verify a validator's withdrawal credentials and current balances. An `EigenPod's` main role is to serve as the fee recipient and/or withdrawal credentials for one or more of a user's validators.
 * The `EigenPodManager` handles `EigenPod` creation and accounting+interactions between users with restaked native ETH and the `DelegationManager`.
-* The `DelayedWithdrawalRouter` imposes a 7-day delay on completing partial beacon chain withdrawals from an `EigenPod`. This is primarily to add a stopgap against a hack being able to instantly withdraw funds (note that all withdrawals from EigenLayer -- other than partial withdrawals earned by validators -- are initiated via the `DelegationManager`).
-* The `EigenLayerBeaconOracle` provides beacon chain block roots for use in various proofs. The oracle is supplied by Succinct's Telepathy protocol ([docs link](https://docs.telepathy.xyz/)).

 If a Staker wants to fully withdraw from the beacon chain, they need to perform these additional steps before their withdrawal is completable:

-If a Staker wants to withdraw consensus rewards from the beacon chain, they do NOT go through the `DelegationManager`. This is the only withdrawal type that is not initiated in the `DelegationManager`:
+As the Staker's `EigenPod` accumulates consensus layer or execution layer yield, the `EigenPod's` balance will increase. The Staker can Checkpoint their validator to claim this yield as shares, which can either remain staked in EigenLayer or be withdrawn via the `DelegationManager` withdrawal queue:
