 # package-zipper
 
-Zips a package based on the information in info.rkt
+Creates a clean, versioned ZIP archive of the current Racket package.
+
+```racket
+(require package-zipper)
+(zip-package)
+```
+
+`zip-package` reads `version` from the current directory's `info.rkt`.
+For a directory named `racket-upnp` with version `"5.0"`, it creates:
+
+```text
+../racket-upnp-5.0.zip
+```
+
+The ZIP recursively contains the package files, except for:
+
+- `.git`
+- names ending in `~`
+- names ending in `.bak`
+- `.html`, `.js`, and `.css` files below `scribblings` or `scribbles`
+
+The comparisons for `.bak` and the Scribble web extensions are
+case-insensitive.
+
+Install this source directory as a linked package during development:
+
+```sh
+raco pkg install --auto --link .
+```
