-Please replace `your_username`, `your_password`, and `your_device` with your actual CalDAV server username, password, and device respectively. In this example, we're using Apple's iCloud CalDAV server. You'll need to replace this with the URI of your own CalDAV server if you're not using iCloud.
+Please replace `caldavendpoint.com` `your_username`, `your_password`, and `your_device` with your actual CalDAV server, username, password, and serial device respectively.
 
-## Note
+The device is a serial device that flashes an led when it receives data. On Linux, this is usually `/dev/ttyUSB0`. On macOS, this is usually `/dev/cu.usbserial-0001`. On Windows, this is usually `COM1`.
 
-Ensure you have the necessary dependencies installed on your system and you have the correct permissions to access the specified device. 
+If you want to use this I highly recommend pairing it with the Raspberry Pi Pico and [this project](https://github.com/famiclone6502/DIY_Datalink_Adapter). It is the cheapest and easiest way to get a serial device that works with the Timex Datalink watch.
 
-The tool currently works with events that have attendees and converts event times to Eastern Standard Time (EST). Events are sorted by time before syncing to the watch.
