How to learn without documents?

In december 2018 I bought the PICkit2 from Vellman EDU10 to learn from beginning the PIC programming.

Now I have installed the software MPLAB X IDE v5.10 and I coult load the first lesson “Hello World”. Now I want to read about the details on “http://ww1.microchip.com/downloads/en/DeviceDoc/41296B.pdf”, but this file dosen’t exist anymore, as all other lessons too.

How this board can be used now? For a beginner as me?
Many thanks in advanced

The file containing the lessons seems to be still available here.

Many thanks for the fast answer and even more that it still exist. Now I can work on it and try to understand it.

No problem at all!
I wish you success in PIC programming!
