@@ -6,8 +6,10 @@ This directory includes contracts to build accounts for ERC-4337. These include:
 
  * {AccountCore}: An ERC-4337 smart account implementation that includes the core logic to process user operations.
  * {Account}: An extension of `AccountCore` that implements the recommended features for ERC-4337 smart accounts.
- * {AccountSignerERC7702}: An account implementation with low-level signature validation performed by an EOA.
+ * {AccountERC7579}: An extension of `AccountCore` that implements support for ERC-7579 modules.
+ * {AccountERC7579Hooked}: An extension of `AccountERC7579` with support for a single hook module (type 4).
  * {ERC7821}: Minimal batch executor implementation contracts. Useful to enable easy batch execution for smart contracts.
