Hi there, I'm new in T4 Framework and I got directly an error on my first steps. I tried to add a custom font, so I created a mulish.css and placed it into "/templates/t4_bs5_blank/fonts/mulish/mulish.css". As described in the documentation I've now entered this path into the field and when I hit "add font" I get a error message "Could not add font. Please check font url".
What or where is the mistake? Have I done something wrong or forgotten?!
