Wrote script for one of the exsisting files- how do I upload

[Jeshi]

Upload it as if it's an original script but make the name identical to the file you're making it the script to, and in the description state "This is the script to <Filename> by <Maker of original file>" And while at first it will be in the system separately it will eventually be fused into the original file.

If there is a better way I'm unaware of it.
