 ## compiling a standalone version
+
 the standalone versions are rather big, so it's a good idea to compress them for distribution.

 run `./release.sh`.
 
-the binary will be located at `./out/release/linux/buypeeb`, with a [zstandard](https://facebook.github.io/zstd/) compressed version at `buypeeb.tar.zst` in the same directory.
