-# User Guide
+# Bari user guide
+
+**Bari** is a simple chatbot that can keep track of tasks for you.
+Enter a command and your task list will be updated automatically – less fuss than
+using some other application for a notepad and having to manually update each and
+every aspect of the tasks as they come and are done.
+
+The name is that of an Italian city, known for its pasta, its Adriatic coast and
+Saint Nicholas.

 ## Features 
 
-### Feature 1 
-Description of feature.
+* Minimalistic user interface
+* Support for to-dos, events and deadlines
+* Support for finding and sorting tasks
+* Auto-saving of tasks after each command
+* Export and import of tasks, saved in `tasks.txt` in the same folder
+as the application
+
+## Commands
+
+`todo [description]`  
+`event [description] /at [time]`  
+`deadline [description] /by [time]`
+
+Add a task of the corresponding type to the task list. Bari will display
+the task you have just entered, followed by the number of tasks in the list
+after that addition.
+
+`time` is a full date and time in the format `day#/month#/yyyy hhmm`, e.g.
+`1/4/2019 1201` means 1 April 2019, 12:01. Bari will display dates in this "natural" format
+in the user interface.
+
+----
+
+`done [index]`
+
+Mark the task at the given index in the task list as done. Marking a task already done
+has no effect; in any case Bari will show you which task you just marked as done.
+
+The index of a task is between 1 and _n_ inclusive, where _n_ is the number of tasks
+in the task list. An error will be raised if the provided index is non-numeric
+or outside this range. 
+
+----
+
+`delete [index]`
+
+Delete the task at the given index in the task list. Bari will display the task that was
+just deleted, so you may enter it again if the deletion was by mistake.
+
+The permissible values of the index are the same as for the `done` command.
+
+----
+
+`list`
+
+Get Bari to list out all the tasks in your task list. This list will be preceded by the
+number of tasks and will display the corresponding index numbers beside each task.
+
+----
+
+`find [string]`
 
-## Usage
+Find which tasks contain the given string (case-sensitive) and show them. As with `list`,
+the number of matching tasks will be displayed before the list proper.
 
-### `Keyword` - Describe action
+----
 
-Describe action and its outcome.
+`sort`
 
-Example of usage: 
+Quietly sort all tasks by task type, then done status, then description.
+_Quiet_ means that Bari will only tell you that the tasks have been sorted;
+the `list` command then needs to be used to explicitly display them.
 
-`keyword (optional arguments)`
+----
 
-Expected outcome:
+`exit`
 
-`outcome`
+Exit the application. Bari is kind enough to say "Bye!" and keep the window open long
+enough for you to see that message before finally disappearing into the background.
