Need NSIS example script with all necessary files for script to run

Question

I am very new to NSIS, and i was wondering if there is a way to change the splash screen with modern UI, on the first and last pages:

Installer Closing Page

Installer Opening Page

Answer 1

!define MUI_WELCOMEFINISHPAGE_BITMAP "c:\myfiles\wizard.bmp"
!include MUI2.nsh
... 

This is of course documented in the Readme.
