import * as Ps from 'perfect-scrollbar'

// To initialise the plugin, `Ps.initialize` is used.
Ps.initialize(container)

// It can be initialised with optional parameters.

// If the size of your container or content changes, call `update`.

// If you want to destroy the scrollbar, use `destroy`.

// If you want to scroll to somewhere, just use a `scrollTop` property and update.
