-there are two self-contained "binaries":
-* [copyparty-sfx.py](https://github.com/9001/copyparty/releases/latest/download/copyparty-sfx.py) -- pure python, works everywhere, **recommended**
-* [copyparty-sfx.sh](https://github.com/9001/copyparty/releases/latest/download/copyparty-sfx.sh) -- smaller, but only for linux and macos, kinda deprecated
-
-launch either of them (**use sfx.py on systemd**) and it'll unpack and run copyparty, assuming you have python installed of course
-
-pls note that `copyparty-sfx.sh` will fail if you rename `copyparty-sfx.py` to `copyparty.py` and keep it in the same folder because `sys.path` is funky
