-All these dependencies should be removable because, in general, build tools are now using the new `videojs-generate-*` libraries. This should make it easier to manage dependencies by offloading much of that work to the Video.js organization. The behavior of these new tools is customizable by editing the files in `scripts/`.
+#### `videojs-generate-postcss-config`
+```
+autoprefixer
+postcss-banner

-Finally, be sure to run, at minimum, `npm test` afterward to make sure your stuff still works!
+No longer needed for other reasons
+* `serve-static`: replaced by `karma-static-server`
+* `in-publish`: replaced by using `prepublishOnly` via a new version of npm
+* `mkdirp`: replaced by using `shx`
+* `rimraf`: replaced by using `shx`
