Hello @Santtu_Soderholm,
You should not provide the fonts through the package. In order to maintain font discoverability, the user of the template should install the font on their system.

Could it be possible to not copy the fonts folder in this repository, and add a link in the README pointing directly to this folder on your GitHub repo? Having it in this repository doesn’t make it particularly easier to access, and all these files are quite heavy.
