how should i download sf4

[Keplow]

basically idk what to download with

there is the twitch download thing but there is also the other thing to download with, idk what to use, i currently only have the twitch launcher thing

[Undertakerin]

just search in twitch launcher for sky factory 4 from darkosto and download it with the launcher.
or download it from curseforge: https://www.curseforge.com/minecraft/modpacks/skyfactory-4/files/3012798  
version 4.2.2,  name a folder SkyFactory 4 in the Instances Folder from twitch and extract the files into the SkyFactory 4 Folder, open twitch launcher and you may have a new profile named skyfactory 4, start it and you can play.

or download the craftersland launcher and choose sky factory 4 or use the ATLauncher or get the multimc launcher and install the modpack via this launcher.
