+
+## Exiting program and Saving data
+
+__Format:__
+- `bye`
+
+Typing `bye` exits the program and automatically saves the current session data into a `data.txt` file. A new `data.txt` will be created if one doesn't exist already.
+
+## FAQ
+
+Q: Can I edit the data file directly or transfer it to another device? <br>
+A: Data storage is done by converting each task and their details to strings and parsing them when loading it for a new session. As such, invalid changes to the `data.txt` file could cause problems and it is not recommended to directly edit the file.
+To transfer data to another device, just copy the `data.txt` file to the `data` directory of the `tsundere.jar` file.
