 ## Setting up allowances
 
 The contract is designed as a single point registry. This way not every Safe needs to deploy their own module and it is possible that this module is shared between different Safes.
 
-To set an allowance for a Safe it is first require that the Safe add a **delegate**. For this a Safe transaction needs to be executed that calls `addDelegate`. This method will add the specified **delegate** for `msg.sender`, which is the Safe in case of a Safe transaction. The `addDelegate` method can be called multiple times with the same address for a **delegate** without failure.

 Once a **delegate** has been enabled it is possible to set an allowance for that **delegate**. For this a Safe transaction needs to be executed that calls `setAllowance`.
 
-To delete an allowance for a specific token a Safe transactions needs to be executed that calls `deleteAllowance`. Another way is to remove the **delegate** with a Safe transaction that calls `removeDelegate`, but this will remove all allowances for this delegate.

 Note: calling `setAllowance` will not change the `spent` value of an allowance. To reset the `spent` value you need to call `resetAllowance`.

 Anyone can execute the transfer as long as they provide the [transfer authorization](#transfer-authorization) of a valid **delegate**. To execute the transfer the `executeAllowanceTransfer` method needs to be called, that checks the signature and calls the Safe to perform the transfer.

+When calling the Safe there are two cases that need to be differentiated: an Ether transfer, and a token transfer.
 - In case of an **Ether transfer** the module instructs the Safe to transfer the specified amount to the receiver (so no data is provided).
 - In case of a **token transfer** the module instructs the Safe to call the transfer method on the token contract to transfer the specified amount to the receiver (so a value of `0` is provided).
 
 ## One time allowances
 
-If the `resetTimeMin` time of an allowance is `0` then the allowance will not automatically renew. This means when the `delegate` has used up the allowance it is necessary "reset" the allowance by performing a Safe transaction that calls `resetAllowance`.

 ## Recurring allowances
 If `resetTimeMin` is set to any value greater than `0` the allowance will automatically renew after the specified amount of minutes based on the last reset time. The initial reset time can be specified with `resetBaseMin`. This can be used to set the time of day the allowance is renewed.

 The contract has been designed to improve the gas usage when executing a transfer and to make it easy to interact with the contract. Because of this configuration changes (e.g. adding or removing allowance and delegates) are not optimized on gas usage.

 - The maximum time span that can be used for the reset is `2**16` minutes. This corresponds to around 45 days, which is more than one month and should be sufficient for most use cases.
 - The maximum reset time would be the unix epoch of `(2**32) * 60`. This is in the year 10136.

 To make it easier to allow querying for allowances two more data structures have been added to the contract: `delegates` and `tokens`.
 
-`delegates` stores all the delegates for a specific Safe in a double linked list. For this we also store an entry point to that double linked list in `delegatesStart`. Each delegate is identified by a `uint48` which is the first **6bytes** of the delegate address. Because of this is can theoretically come to collisions. As the index points to a struct containing the `address` of the delgate, the `next` index and the `prev` index, it is possible to verify which address was used to get the index. In case of collisions we recommend to generate a new delegate.

 `tokens` is a list that is appended when ever an allowance is set for a token for the first time. The tokens will never be removed from this list.

 ## Considerations
 
 - If storage rent is introduced for contracts it might be possible (depending on the rent implementation) to perform a grieving attack, as anyone can register allowances.
-- The information provided by `delegates` and `tokens` could be rebuild using event and therefore these would not be necessary in the contract (this would make some consistency checks unnecessary and save gas).
