I'm using a template called Legrand Orange Book from http://www.latextemplates.com

I don't know how to accomplish the instructions of the author. The instructions in the template say:

Compiling this template: This template uses biber for its bibliography and makeindex for its index. This means that to update the bibliography and index in this template you will need to run the following sequence of commands in the template directory:

1) pdflatex main
2) makeindex main.idx -s StyleInd.ist
3) biber main
4) pdflatex main

I use texmaker (for windows) but I don't know how I can satisfy the 4 conditions, besides I've just downloaded biber and I don't know how to set it up neither. Can you give me a hand?
