For Overleaf users!
Upload the Corvinus recommended fonts to Overleaf and Overleaf manages the font installation.
The required font files are as follows:

Calluna_Bold_Italic.otf
Calluna_Bold.otf
Calluna_Heavy.otf
Calluna_Italic.otf
Calluna_Light.otf
Calluna_Regular.otf
Calluna_Semi_Bold_Italic.otf
Calluna_Semi_Bold.otf
TT_Nooks_Bold.otf
TT_Nooks_Heavy.otf
TT_Nooks_Light.otf
TT_Nooks_Regular.otf

If you need these files send an email to me, I share an Overleaf link where you can find corvinusmetropolis installed.
