+`Timer` accepts the following arguments when it's created. All arguments are optional:
 
 - **`name`:** An optional name for your timer
 - **`text`:** The text shown when your timer ends. It should contain a `{}` placeholder that will be filled by the elapsed time in seconds (default: `"Elapsed time: {:.4f} seconds"`)
-- **`logger`:** A function/callable that takes a string argument, and will report the elapsed time when the logger is stopped (default: `print()`)
+- **`logger`:** A function/callable that takes a string argument and will report the elapsed time when the logger is stopped (default: `print()`)
 
 You can turn off explicit reporting of the elapsed time by setting `logger=None`.
 
-In the template text, you can also use explicit attributes to refer to the `name` of the timer, or log the elapsed time in `milliseconds`, `seconds` (the default), or `minutes`. For example:
