Help installing custom content for sims 4

Okay. I have been trying to find the answer to this question, literally for years now.  Installing Script mods . The instructions say that the mods come in package and scripts. The instructions say the package files CAN go into a folder inside of the mods folder. I got that. (INSTRUCTIONS SAY, DO NOT UNZIP THE SCRIPT FILES),  Most mods that come with "SCRIPT", Files DO NOT HAVE THE "SCRIPT FILE", Zipped within a separate zip file. The "SCRIPT" File is LOOSE, Along with the Package File or files.  (You have to UNZIP the mod to get at the package files), in doing so, you will have (EXAMPLE),, two or three package files,  then one or more files ending in (.Script),  Do we have to make a zip file with the Script file inside now?????  We cant install it because it was unzipped to get the package files.  NO BODY HAS ANSWERED THIS QUESTION. ARE MODDERS TO LAZY TO ZIP THE SCRIPT FILES THEN ZIP THAT ZIP FILE WITH THEIR PACKAGE FILES INTO ANOTHER ZIP????????
