-# file read
+# on ML start
 
-Reads the contents of a file from the file system
+Start an [event handler](https://makecode.microbit.org/---docs#doc:reference/event-handler) (part of the program that will run when something happens) This handler works when when the ML model’s estimated action changes to the action you select.
 
 ```sig
-files.read("/path/to/file.txt", "UTF-8")
+ml.onStart(ml.event.Unknown, function () {
+    basic.showString("?")
+})
 ```
 
+The ML model updates its estimated action several times a second, but this block only runs when the estimated action changes.
+
 ## Parameters
 
-* **path**: a string that contains the path to the file on disk
-* **encoding**: the encoding of the file to be read
+- **action**: action one of the actions the machine learning model was trained on. The special value unknown represents the case where no action has a certainty above the recognition point.
 
 ## Example
 
 This example reads from a file on disk and prints the contents to the console.
 
 ```blocks
-const contents = files.read("/path/to/file.txt", "UTF-8");
-console.log(contents)
+ml.onStart(ml.event.Unknown, function () {
+    music._playDefaultBackground(music.builtInPlayableMelody(Melodies.Dadadadum), music.PlaybackMode.InBackground)
+})
 ```
