-// Describe the action and its outcome.
+# Feature Usage
+## Adding Tasks
+The bot is able to track 3 types of tasks: Todos, Deadlines and Events.
 
-// Give examples of usage
+### Adding Todos
+Todos are the simplest of all tasks and are not associated with any time period.
 
-Example: `keyword (optional arguments)`
+To get Lawrence to track a todo, use the `todo` command.
+Usage:
+```
+todo <todo-name>
+```
+If successful, the chatbot will respond with a readback of the added Todo.
+
+### Adding Deadlines
+Deadlines are similar to Todos, but require an extra date parameter.
+
+To get Lawrence to track a deadline use the `deadline` command.
+Usage:
+```
+deadline <deadline-name> /by <date>
+```
+If successful, the chatbot will respond with a readback of the added Deadline.
+
+### Adding Events
+Events are similar to Deadlines, but require a start date and end date.
 
-// A description of the expected outcome goes here
+To get Lawrence to track an Event, use the `event` command.
+Usage:
+```
+event <event-name> /from <date> /to <date>
+```
+If successful, the chatbot will respond with a readback of the added Event.
 
+### Successful Add
+If the command was executed successfully, the bot should respond with a readback of the added Task.
 ```
-expected output
+Alright, added <task-details> to the list.
+There are currently <total-task-amount> task(s) in the list.
 ```
+### Unsucccessful Add
+If there was any error when processing the task to be added, the bot will attempt to diagnose and inform you of the error in the command.
+
+## Updating Completion Statuses
+Existing tasks can be marked as complete or incomplete using the `mark` and `unmark` commands respectively.
+
+Usage:
+- `mark 1` will mark the first task in the list as complete
+- `unmark 2` will mark the second task in the list as incomplete.
+
+If the specified task number does not exist, the bot will not proceed with the request.
+Examples of invalid task numbers:
+- `mark -1`
+- `unmark 6` when there are only `5` tasks in the list.
+
+## Deleting Tasks
+Existing tasks can be deleted using the `delete` command with a specified task number.
+Usage:
+- `delete 1` will delete the first task in the list.
+
+If the specified task number does not exist, the bot will not proceed with the request.
+Examples of invalid task numbers:
+- `delete -1`
+- `delete 6` when there are only `5` tasks in the list.
+
+## Viewing Tasks in the List
+The tasks currently tracked by Lawrence can be viewed using the `list` command.
+Usage:
+```
+list
+```
+
+## Searching for Tasks
+The tasks currently tracked by Lawrence can be searched by their descriptions.
+To do so, use the `find` command.
+
+Usage:
+```
+find <keyword-in-task-description>
+```
+The bot will consolidate and display the tasks that match the specified keywords.
+
+If no matches are found, the bot will also notify you of the result.
+
+## Exiting the Program
+To exit the program, use the `bye` command to terminate the chatbot session.
+Usage:
+```
+bye
+```
+
+The tasks added are automatically saved and will persist between chatbot sessions.
+
+# Lenient Syntax
+The bot is able to recognise **some** abbreviated commands to reduce the amount of typing the user needs to do.
+Commands can be recognised without fully spelling out the command.
 
-## Feature ABC
+Examples include:
+- `t` and `to` can be recognised as the `todo` command
+- `m` can be recognised as the `mark` command
+- `u` can be recognised as the `unmark` command
 
-// Feature details
+## Ambiguity
+However, it should be noted that the `delete` and `deadline` command can be ambiguous if shortened to a single letter.
 
+As such, the bot will refuse to process commands such as `d` as it may mean two different things.
 
-## Feature XYZ
+Luckily, the bot is still able to recognise a slightly longer but still shortened form of these commands:
+- `del` is recognised as `delete`
+- `deadl` is recognised as `deadline`
 
-// Feature details
+# Dealing with Errors
+If there was any problem with the execution of a command, the bot will attempt to diagnose it and let you know of any modifications that need to be made to the command.
