effects loop - signal chain question

[littleredguitars2]

i need to add a noise suppressor to my 5150 rig and someone mentioned before that it needs to be through the effects loop. i've never used the effects loop. so what would my signal chain look like? i normally would go from guitar > in NS > out NS > amp input. thats it.

guitar > amp in > loop send > NS in > NS out > loop return
