+# Advanced
+## Data Storage
+All the data is saved in the file `./data/duke.txt`. You can modify task list by directly editing
+this file. Each line of the file describes one task. The format is the following:
+ ```
+,,,
+ ```
+- `TASK Type` is `T` for todo task, `D` for deadline, and `E` for event tasks.
+- `COMPLETION STATUS` is 0 or 1 depending on whether the task is completed or not.
+- `DESCRIPTION` is the description of the task.
+- Currently, `ARGS...` only take in a date for deadline and events. The date must be in the
+ format `yyyy-MM-dd`. Specifically, day and month number should not have leading zeros.
