+This protocol has only one function, which receives a list of events. These events are then written to the file with the `path` location.
 
 `registry` and `path` are fields passed to the record. `registry` is automatically injected by Mirabelle and is a [https://micrometer.io/](micrometer) registry, and can be used to add metrics on your I/O component.
 
 The `path` parameter will be set by the user (it's explained a bit later in the documentation).
