Question about E ­VISA TRAVEL INSURANCE

I just applied for my Turkish E-Visa and I was given 3 documents to download - the visa, the receipt, and the E ­ VISA TRAVEL INSURANCE. I dont understand if this is a travel + medical insurance or do i need to get one separately which covers the trip. I got it from https://evisa.gov.tr/en/ which as far as i know, is the legitimate website.

Any help understanding what the document is and what it means for the above question will be appreciated. Thanks!
