Old pool going down. New pool help

Old pool is an Intex ultra frame pool 20x48.
it has lasted 8 years with me. And one year with original owner.

so it comes down tomorrow and gets re-homed.
now it’s time to upgrade to something more permanent.

Came across a Fanta Sea Island pool
12x24 rectangular pool.
aluminum admiral deck included.

but no manual. No installation book. Nothing.
