Replacing like for like fixture is very simple..... BUT .... based upon your asking how to, I am assuming you are not familiar with electrical wiring. Therefore best advice would be to contact a local electrician, or handyman service. Especially if you are looking to change the fixture style because measures may need to be added for support, alignment etc. of the new fixture.
To do this yourself... you will need a basic electrical knowledge and understanding.... Youtube can give you some info.... and instructions... but if you are not very handy....
First I would see if your local Lowe's or Home Depot offers low cost installation... when you purchase a fixture there.

Maybe this would help. If your fixture is on the ceiling it will be the same basic principle as the wall fixture.

Turn main breaker off. Remove old light. Connect new light with wires black to black white to white. Ground to ground. Your done
Why are you replacing it?
