You will have to present several documents at the Schengen port of entry, in order to be permitted to enter, if you are a non-EU/Schengen country national, regardless if you are a visa-exempt or not.
The documents you need to provide when entering the Schengen Area are as follows:

Valid Passport. Issued within the previous 10 years and valid for at least 3 months after the date you intend to leave the EU.

Schengen Visa. If you are a national of one of the third countries in need of a visa.

EU/Schengen border officials may also ask for other information and documents such as sufficient funds, proof of accommodation, how long you intend to stay, round-trip airline ticket, purpose of your entry, travel insurance, invitation letter, etc.
Please, make sure that the border officer gives you an entry stamp in your passport when you enter the Schengen area. Without a stamp, you could be fined or detained.
