In the most cases, an 8GB MicroSD card should suffice, but 16GB or higher is preferred. For the r/w speed of the memory card, Class 10 has been quite popular. Theoretically, within a certain range, the higher the speed, the better the performance.
Then, use Etcher to burn the system image to the MicroSD card and insert the card into the Raspberry Pi.
