 ## Design & implementation
 
+### Budget Management
+
+#### Implementation
+The Budget Management feature allows users to set financial limits for the various categories and monitor their spending. 
+This feature's objective is to give users the ability to stay within their financial goals and avoid overspending.
+
+This feature is orchestrated by `ListBudgetCommand` and `SetBudgetCommand`, which are initialised by the `Parser` 
+class. Below is a description of the key class attributes and methods involved in the budget setting and listing 
+process:
+
+##### Class Attributes for `SetBudgetCommand`:
+| Class Attribute | Variable Type | Relevance                                                           |
+|-----------------|---------------|---------------------------------------------------------------------|
+| expenseList     | ExpenseList   | Object containing the list of expenses to check against set budgets |
+| category        | String        | The category for which the budget is being set                      |
+| budget          | double        | The budget amount to be set for the category                        |
+
+##### Class Attributes for `ListBudgetCommand`:
+| Class Attribute | Variable Type | Relevance                                                           |
+|-----------------|---------------|---------------------------------------------------------------------|
+| expenseList     | ExpenseList   | Object containing the list of expenses to check against set budgets |
+
+
+Upon the call of the `execute()` method in `BudgetBuddy` using `command.execute()`, `SetBudgetCommand` will update the 
+budget in `ExpenseList` using `setBudget`. Similarly, `ListBudgetCommand` will fetch and display all categories with 
+their budgets using `getBudgets`, and highlight those that are above the set budget.
+
+##### Key Methods used from `ExpenseList`
+| Method                      | Return Type   | Relevance                                                          |
+|-----------------------------|---------------|--------------------------------------------------------------------|
+| setBudget(category, budget) | void          | Sets or updates the budget for a given category in the ExpenseList |
+| getBudgets()                | List<Budget>  | Retrieves the list of all budgets set                              |
+
+The `ListBudgetCommand`'s updated execution function now features an improved display that not only shows the budget, 
+spent amount, and remaining balance but also clearly indicates when the budget has been exceeded. If the expenses 
+surpass the budget, instead of showing a negative remaining balance, it displays "Exceeded", providing a straightforward
+and immediate visual cue that the budget limits have been surpassed.
+
+The "Categories above budget" section offers a concise table summarizing which categories have gone over the budget and
+by what amount, making it easy for users to identify areas of concern.

+The Set Budget feature allows users to allocate a specific budget to various categories. This feature is managed by the
