First you need to prepare your file..

Parts you want to show in the index need to be formated as Title 1, Title 2 (there is a button that show the different text properties)

Then you go to Insert then you choose Reference ---> Index and Table

There will be a button to mark down an entry and then you start to mark every entry you want in the index...

Then lastly you insert the index...

I cannot check out correclty the names in english due that my word is spanish I did the best translation possible!

but basically the process I described Its the one I use when I need it
