+# BuddyBot project template
+
+BuddyBot is a simple task management chatbot that helps you keep track of your to-dos, deadlines, and events.
+
+## Getting Started
+
+1. Run BuddyBot using the command:
+   ```
+   java -jar BuddyBot.jar
+   ```
+If you are using IntelliJ, you can also run it by clicking the Run button.
+
+2. Use commands to add, view, and manage your tasks
+
+3. Tasks are automatically saved between sessions
+
+## Available Commands
+
+### Adding Tasks
+
+| Command | Format | Example | Description |
+|---------|--------|---------|-------------|
+| `todo` | `todo TASK_DESCRIPTION` | `todo read book` | Adds a simple to-do task |
+| `deadline` | `deadline TASK_DESCRIPTION /by DEADLINE` | `deadline return book /by June 6th` | Adds a task with a deadline |
+| `event` | `event TASK_DESCRIPTION /from START_TIME /to END_TIME` | `event team meeting /from Monday 2pm /to Monday 4pm` | Adds an event with start and end times |
+
+### Managing Tasks
+
+| Command | Format | Example | Description |
+|---------|--------|---------|-------------|
+| `list` | `list` | `list` | Shows all tasks |
+| `mark` | `mark TASK_NUMBER` | `mark 3` | Marks a task as done |
+| `unmark` | `unmark TASK_NUMBER` | `unmark 2` | Marks a task as not done |
+| `delete` | `delete TASK_NUMBER` | `delete 1` | Removes a task |
+| `find` | `find KEYWORD` | `find book` | Finds tasks containing the keyword |
+| `bye` | `bye` | `bye` | Exits the program |
+
+## Task Formats
+
+Tasks are displayed in the following format:
+
+- **To-Do**: `[T][✓] read book` (✓ means done, ✗ means not done)
+- **Deadline**: `[D][✓] return book (by: June 6th)`
+- **Event**: `[E][✓] team meeting (from: Monday 2pm to: Monday 4pm)`
+
+## Examples
+
+### Adding Different Types of Tasks
+
+```
+todo finish homework
+deadline complete project /by Friday
+event doctor appointment /from Tuesday 10am /to Tuesday 11am
+```
+
+### Managing Your Tasks
+
+```
+list
+mark 2
+unmark 3
+delete 1
+```
+
+### Finding Tasks
+
+```
+find project
+    ____________________________________________________________
+     Here are the matching tasks in your list:
+     1.[T][✗] start new project
+     2.[D][✓] complete project (by: Friday)
+```
+
+## Tips
+
+- Task numbers start from 1 (not 0)
+- All commands are case-insensitive (`TODO` works the same as `todo`)
+- Your tasks are automatically saved to a file for your next session
+- Use specific keywords when searching to find relevant tasks more easily
+
+## Error Messages
+
+If you see an error message, check that you're using the correct command format:
+
+- For deadlines, use `/by` to specify the due date
+- For events, use both `/from` and `/to` to specify start and end times
+- Task numbers must be valid (can't mark or delete task #5 if you only have 3 tasks)
