+> Introducing **Bobby**, a revolutionary (*okay, not really*) new way to track your tasks!
+
+Bobby is structured as a chatbot that users can talk with. By typing in comments and
+sending them to Bobby as a chat message, he will be able to execute these commands and return
+the relevant information
+
+Additionally, Bobby automatically saves the task list to a file with every command execution,
+meaning that there is data persistence between different sessions!
+
+## Adding todos
+
+A todo task is a named task without any deadlines.
+Bobby is able to add such tasks to the task list
+
+Example: `todo Homework`
+
+```
+Got it. I've added this task:
+[T][] Homework
+Now you have x tasks in the list
+```
 
-// Product intro goes here
 
 ## Adding deadlines
 
-// Describe the action and its outcome.
+A deadline task is a named task with a set datetime (the deadline).
+Bobby is also able to add such tasks to the task list
+
+Example: `deadline Assignment /by 2019-10-10 15:10`
 
-// Give examples of usage
+```
+Got it. I've added this task:
+[D][] Assignment (by: Oct 10 2019 10:10)
+Now you have x tasks in the list
+```
 
-Example: `keyword (optional arguments)`
+Note that it is necessary to provide the /by argument, followed by a datetime
+with the YYYY-MM-DD HH:MM format
 
-// A description of the expected outcome goes here
+## Adding events
 
+An event task is a named task with 2 set datetimes (from and to).
+Bobby is able to add such tasks to the task list
+
+Example: `event Concert /from 2020-10-05 16:30 /to 2020-10-05 19:00`
+
+```
+Got it. I've added this task:
+[E][] Concert (from: Oct 05 2020 16:30 to: Oct 05 2020 19:00)
+Now you have x tasks in the list
+```
+
+Note that it is necessary to provide the /from and /to arguments, followed by 2 datetimes
+with the YYYY-MM-DD HH:MM format
+
+## Listing tasks
+Bobby lets you view the task list, with the `list` command
+
+Example: `list`
 ```
-expected output
+Here are the tasks in your list:
+1. [T][] Homework
+2. [D][] Assignment (by: Oct 10 2019 10:10)
+3. [E][] Concert (from: Oct 05 2020 16:30 to: Oct 05 2020 19:00) 
 ```
 
-## Feature ABC
+## Marking tasks
 
-// Feature details
+Bobby gives you the ability to mark tasks as done, and also unmark them to indicate that they
+are not done. After the task is marked, Bobby returns the string representation of the task
 
+Example: `mark 1`
+```
+Nice! I've marked this task as done:
+[T][X] Homework
+```
 
-## Feature XYZ
+Example: `unmark 1`
+```
+Ok, I've marked this task as not done yet:
+[T][] Homework
+```
+
+Note that the number argument after `mark` and `unmark` refers to the number of the task as shown by the `list` command
+
+## Finding tasks
+Bobby also lets users find specific tasks with a query
+Any tasks with a name that includes the query will be returned.
+Note that the search is *not* case-sensitive!
+
+Example: `find assigment`
+```
+Here are the tasks matching your query:
+2. [D][] Assignment (by: Oct 10 2019 10:10)
+```
+
+## Removing tasks
+Of course, Bobby also lets users remove any tasks that no longer need to be tracked by the task list.
+This command is similar in format to `mark`
+
+Example: `delete 3`
+```
+Got it. I've removed this task:
+[E][] Concert (from: Oct 05 2020 16:30 to: Oct 05 2020 19:00) 
+Now you have 2 tasks in the list
+```
+
+Note that the number argument after `delete` refers to the number of the task as shown by the `list` command
+
+## Sorting tasks
+Sometimes, we want to be able to conveniently order the tasks by their dates and times, so that we can easily know
+what to do next. Bobby allows users to do just that, with the `sort` command!
+
+Right now, Bobby is able to sort the tasklist in two ways: ascending via the `asc` argument, and descending via the `desc`
+argument. 
+
+For sorting, todo tasks (that do not have datetimes) will be at the top of the list
+
+Example: `sort asc`
+```
+List has been sorted in ascending order!
+```
+
+Example: `sort desc`
+```
+List has been sorted in descending order!
+```

+After this command is executed, the next time users `list` all the tasks out, it will be in the desired order
