This video tutorial explains how to enhance a basic website by adding data import functionality using Shiny. It covers the implementation of a file input feature in the UI and server-side script, allowing users to upload their own data. The tutorial also discusses adding a separator input for more flexible data handling, enabling the import of different data formats. The video concludes with a preview of the next topic on conditional panels.

What is the initial step discussed for allowing users to import their own data into a website?
