I wasn't directly able to use this template, as I don't have Word and it's not supported on (and doesn't 100% work with) LibreOffice or Apache OpenOffice. However, I was able to peek "under the hood" enough to see that the work Laura has done here is amazing, and I will readily recommend this without reservation if you're using MS Word.
This template uses clearly-labeled paragraph and character styles and does a great job at explaining how to use those. (Ironically, it also proved a great educational tool for LibreOffice as I attempted to reverse-engineer some of the things that weren't working for me and had to learn new ways of doing them in LO.) You won't get a 100% match to the style of the official book releases, because that's simply beyond the scope of what a word processor can do, and you'll need the InDesign or Affinity templates she links in her description. That said, this template absolutely gets you as close as possible inside the limitations of the software. Follow her instructions carefully, and you'll be spitting out great-looking releases in no time at all. Just add Inspiration.
Marvelous work, Laura. 10/10 would definitely recommend!
