Generally great job done! The explanantions are very clear and detailed, various types of diagrams are provided. But there are some repetitive diagrams as well as unnecessary details provided.

should the green dots in front of the methods be positive or negative signs instead?

| listSavings() | void | Prints the savings, filtered by `filterCategory`, to the CLI |
| calculateRemainingSavings() | double | Calculates the remaining amount after deducting total expenses |

The Listing Savings feature follows these steps when a user inputs a command to list savings:

Good display of the class attributes and variable type in a table format

After determining the type of `CommandCreator` object, the Parser initializes the `CommandCreator` object
with all its required parameters.

Great work in giving examples of how your parser works!

| exchangeRates | Map<Currency, Double> | Stores exchange rates with currencies as keys |

When `BudgetBuddy` calls `command.execute()`, `ChangeCurrencyCommand` employs the following methods from `CurrencyConverter` to convert the currency of all financial records:

The three tables above are not properly rendered in the result html. Checking the formatting may help.

the green dots and red square doesn't follow the standard + - notation for public/private members. Maybe using the standard or further explanations can help.

The Storage class can use some further information for developers. Information such as how the save/load function is implemented, how the data is formatted in the output files when writing and how the data is interpreted when reading.

All in all the team has done a marvellous job in documenting DG! It is a comprehensive and detailed breakdown of their system architecture with interactions between classes well explained. Further improvement suggestions could be to have a consistent standard with the UML diagrams (background colour, activation bar etc), such that the presentation is more coherent.

Rendering errors for the command table in HTML view. Recommend checking the formatting for the tables again.

The following UML Sequence diagram shows how `SetBudgetCommand` works when a user sets a budget for a category in the
following format: `set budget c/<Category> b/<Amount>`

A clear and concise drawing of the UML diagram! However, would further recommend to standardise all return commands to use dotted arrows.

by what amount, making it easy for users to identify areas of concern.


#### Sequence diagrams

A minor issue with the consistency of the sequence diagrams: The diagram here is a concise drawing of UML while the later ones utilise the full annotation. Would it be possible for such standards to be consistent (e.g. Available drawing of activation bar for all of them)?

Overall, the DG is detailed and well-explained. A few minor issues such as format and notations used can be improved. Great job!

##### 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 |

It is difficult to understand the tables under the class attributes for SetBudgetCommand, ListBudgetCommand and ExpenseList. The formatting here can definitely be improved.

The class diagram here doesn't follow the standard used in the course website. The access modifiers are supposed to be denoted using + for public and - for private members.
