The same as installing any other Operating System for an RPi board.

What is the reason for wanting an obsoleted Operating System, and what do you think is the impediment to installing it?

There is nothing to install, you create a bootable SD Card using PiImager and choose Custom Option:

i want to build this project
https://circuitdigest.com/microcontroll ... ding-robot
and this need to Raspbian Jessie OS. I can use another OS for this project?

So you have an older Raspbian Pi model ?

Raspbian is backward compatible not foreward compatible.

Looks to me like that python 2 code they are using and the sensor / motor driver would all work fine using python 2 on the latest RaspiOS (Buster).

If you are going to build that project please don't follow the connection diagram for the ultrasonic sensor , powering it with 5V as required will result in the echo also being at 5V, this will damage you pi gpio over time finally resulting in the failing pi.

you need to add a potential divider circuit to the echo output, like this

and I would not power the motors from the 5V pin of the gpio header.

If so, that's fine

really ? are you sure ?
if i dont use voltage divider which model of raspberry pi damaged ?
[sorry i am not good in english]

Yes I am sure,

all raspberry pi's have a 3.3V gpio, applying 5V to a gpio pin will cause latch-up of that pin and damage to the chip, which will spread over time resulting in pi failure.

You will find many warnings on many posts on this forum saying pi gpio is not 5V tolerant.

and from the official doc's
Each of the three banks has its own VDD input pin. On Raspberry Pi, all GPIO banks are supplied from 3.3V. Connection of a GPIO to a voltage higher than 3.3V will likely destroy the GPIO block within the SoC.
