-### [Implemented] List feature
+### [Implemented] List Transactions
 
 ### Description
 
 The list feature allows users to view their existing transactions. This feature includes viewing all the transactions,
 past week's transactions, past month's transactions and transactions from a specified date range.
 
-#### Implementation
+#### Design and Implementation
+
+This feature is facilitated through the `TransactionList#processList`, and it is designed to ensure successful viewing 
+of the desired list as inputs are required in a bite-sized manner. 
 
-This feature is facilitated through the `TransactionList#processList`, where it prompts the user for their choice of
-list they wish to see. After the user inputs the choice, the get functions will store the transactions in a new
-ArrayList and `UserInterface#printPastTransactions` will handle the output of the list.
+This method first executes the `UserInterface#printListOptions` to show users the list options and their indexes which 
+is needed for their inputs. The method will throw an InvalidIndexException if the input is out of the range.
+Depending on the list option chosen by the user, different prompts and messages will be output. For options which 
+require more data by the user, this feature will prompt the user to input the data. Once all required information is 
+gathered, the method will call on the various methods to build an ArrayList of the desired list and print out the list.
