 ## Disk and Serial API
 
 In order for the UI code to be independent of Electron code, there is an API defined at `/preload.js` that describes all the allowed operations.
 
-There are 2 main operation "channels": Serial communication and local Filesystem operations. Both channels offer methods that always return promises and are used mostly using [`async`/`await`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/async_function).
