+/**
+ * @dev Extension of {AccessControl} that allows specifying special rules to manage
+ * the `DEFAULT_ADMIN_ROLE` holder, which is a sensitive role with special permissions
+ * over other roles that may potentially have privileged rights in the system.
+ *
+ * If a specific role doesn't have an admin role assigned, the holder of the
+ * `DEFAULT_ADMIN_ROLE` will have the ability to grant it and revoke it.
+ *
+ * This contract implements the following risk mitigations on top of {AccessControl}:
+ *
+ * * Only one account holds the `DEFAULT_ADMIN_ROLE` since deployment until it's potentially renounced.
+ * * Enforce a 2-step process to transfer the `DEFAULT_ADMIN_ROLE` to another account.
+ * * Enforce a configurable delay between the two steps, with the ability to cancel in between.
+ *   - Even after the timer has passed to avoid locking it forever.
+ * * It is not possible to use another role to manage the `DEFAULT_ADMIN_ROLE`.
+ *
+ * Example usage:
+ *
+ * ```solidity
+ * contract MyToken is AccessControlDefaultAdminRules {
+ *   constructor() AccessControlDefaultAdminRules(
+ *     3 days,
+ *     msg.sender // Explicit initial `DEFAULT_ADMIN_ROLE` holder
+ *    ) {}
+ *}

 This mechanism can be used to create complex permissioning structures resembling organizational charts, but it also provides an easy way to manage simpler applications. `AccessControl` includes a special role, called `DEFAULT_ADMIN_ROLE`, which acts as the **default admin role for all roles**. An account with this role will be able to manage any other role, unless `_setRoleAdmin` is used to select a new admin role.
 
+Since it is the admin for all roles by default, and in fact it is also its own admin, this role carries significant risk. To mitigate this risk we provide xref:api:access.adoc#AccessControlDefaultAdminRules[`AccessControlDefaultAdminRules`], a recommended extension of `AccessControl` that adds a number of enforced security measures for this role: the admin is restricted to a single account, with a 2-step transfer procedure with a delay in between steps.
