For those just joining us, currently Debug level sends some amount of logs to the debug output stream.  However, that should really be a separate, orthogonal option.

```Messages can be written to a custom log file as seen below.  Unfortunately, there is no standard way of getting logs from a device.  There are some services that can help you with this.  You can also invent your own, such as sending the file to a server.```

People that are new to the library don't know about that setting, and there is no reason to advertise it to them.

If I understand correctly logCat and its use in Android development should be well understood by the average Android developer.  I would leave that kind of detail out.  How about just saying this:
> All log messages are sent to logcat in addition to any customer log callbacks.
