• ReadMe mentions OFL + MIT license so we may need to clear this up A quick grep reveals:

Gidole is dual licensed under OFL (÷RFN) and MIT license - pick the one you prefer." Must be changed to "Licensed under the Apache License, Version 2.0

However, a license.txt file exists which is OFL.

• Vertical metrics need fixing (line gaps are enabled atm)
• Name table needs fixing
• Combining marks are missing

Getting the license sorted is going to be the biggest issue. Apart from that, it's a single weight family so it should be easy to fix everything I've pointed out.

Design quality is quite high so it would be a nice family to include.
