I began by looking through the Attiny44 microcontroller´s datasheet, and I traied to understand how the Attiny44's pins works like the Arduno board as I had made some projects using it before. And I found this tutorial from HighLowTec .
First I used Arduino Uno as ISP, and connect the board's pins to the Ardunio
Then Opend the Arduino IDE,and from tools I choosed "Attiny"
And from processor choosed "Attin44"
The first program I made is the to blink the LED
Then the Second program is to used the Button to light the Led
