I'm new to filtered seed, can someone give me an explanation to how to use the generators?

get FSG Mod here [ https://modrinth.com/mod/fsg-mod ] then add it to ur mods and launch the game, then click the seeds icon on menu and choose the filter. then, if u have atum installed, click the gold boots on the main menu. if not, get it here [ https://modrinth.com/mod/atum ]
