 ## Features
 
-- Works both in [node](https://nodejs.org) and in the browser.
-- If a number is supplied to `ms`, a string with a unit is returned.
-- If a string that contains the number is supplied, it returns it as a number (e.g.: it returns `100` for `'100'`).
-- If you pass a string with a number and a valid unit, the number of equivalent ms is returned.
