 *   Keep track of tab position before move and allow for undo motion.
 
+## Developing
+
+The source code is in the `tab-shortcuts` subdirectory, including the manifest
+and javascript files.  To make a release, run `bash make-release.sh` in the
+top-level directory.  This will put a new zip file into a `releases`
+subdirectory, including the version extracted from the manifest.
+
+To update the version number, edit the `version` field in `manifest.json`.
+This is required before uploading a new version to the Chrome Web Store.
+
+Note that `make-release.sh` requires that the `jq` command be installed (which
+is used for parsing the JSON-based manifest file).
