how to install kurtidev font in libre office for typing in hindi

i want to type in hindi in libre office by using kurti dev font because I am familiar with kurti dev font.

You haven’t said what operating system you are using. You will need to download and install the kurti dev font if you have not already done so. Once the font is downloaded restart LibO and it shouldl recognise the font is installed. You then need to set the options in LibO. In Linux this is by selecting TOOLS > OPTIONS > LANGUAGE SETTINGS > LANGUAGES > COMPLEX TEXT LAYOUT > HINDI.
hope this helps… Peter
