+## Features
+Duke is a simple application to help you manage your tasks. The tasks can be categorized into one of the following types:
+* Todos
+* Events (and their starting times)
+* Deadlines (and their due times)
+
+Duke also supports marking tasks as done, deleting, and finding tasks that match a keyword. Your data will be stored locally and automatically loaded whenever you start the app.
+
+## Usage
+**Note:** Times can be either of the following formats:
+* `yy-M-dd H:mm`
+ * E.g.: `20-09-21 05:45` or `20-9-21 5:45`
+* `yyyy-MM-dd'T'HH:mm`
+ * E.g.: `2020-09-21T05:45`
