i cant seam to open any of these files to save them. what am i suppose to use? LFS reset itself or something all my old set ups are gone

i totally dont know how to do any of this. It all makes no sense to me. Like do i make a lfstweak folder and put the files in there? the first two links after i download it says i dont have a program to run the the program. this is totally messed...ahh i hate computers

where do i put this file into? im new to lfs and all this stuff is very confusing...
