On Windows, line ending conversion causes the hashes to change when files are uploaded to Git, so you'll get a ton of errors when trying to install the pack
You'll want to add a .gitattributes file in the root folder with the content * -text - this disables line ending conversion
If you have existing files committed to Git, you'll need to run git rm --cached -r . then git add . to re-add them after adding .gitattributes
You'll also want a .packwizignore file containing .git/** and .gitattributes (same format as .gitignore) so that Git metadata isn't included in the pack index
