 ### File I/O Instrumentation
 
-The Sentry-specific file I/O implementation starts a span out of the active span, bound to the scope for each file I/O operation. The SDK sets the span `operation` to `file.copy`/`file.write`/`file.delete`/`file.open`/`file.read`/`file.rename` and `description` to `filename`, e.g. `file.txt`
+The Sentry-specific file I/O implementation starts a span out of the active span, bound to the scope for each file I/O operation. The SDK sets the span `operation` to `file.copy`/`file.write`/`file.delete`/`file.open`/`file.read`/`file.rename` and `description` to `filename` (for example, `file.txt`).
 
 In addition, the span contains other useful information such as `file.size` (raw number of bytes), `file.path` (an absolute path to the file) and `file.async` (`true` if the called method returns a `Future` or `false` if it's a `Sync` call) as part of the `data` payload.
