 # How do I update brew-cask?
 
-Currently you'll have to `brew rm brew-cask` and then run the command above to reinstall.
+Since this repository is a Tap, you'll pull down the latest Casks with a simple

+`brew outdated` and you can upgrade it via the normal Homebrew workflow.

 Each Cask will then encapsulate and automate the story of how a given
 application should be installed.  If all goes well - I'm hoping to build up a
 community-maintained collection of Casks that becomes the standard way that
 hackers install Mac apps.
 
+# Can I contribute?
+
+__Yes, yes, yes!__ Please fork/pull request to update Casks, to add features,
+to clean up documentation--anything at all that you can do to help out is very
+welcome.
+
+It's also __pretty darn easy__ to create Casks, so please build more of them
+for the software you use. And if `brew-cask` doesn't support the packaging
+format of your software, please open an issue and we can get it working
+together.
+
+The whole idea is to build a _community-maintained_ list of easily installable
+packages, so the community part is important! Every little bit counts.

 # Alfred Integration
 
 I've been using Casks along with Alfred to great effect.  Just add
 `/usr/local/Cellar` as a Search Scope in Alfred's preferences, and then
 applications become available in Alfred immediately after a `brew cask
-install`.  Your fingertips will thank you!

+With this setup, you don't actually need `brew cask linkapps` if you always
+open your apps from Alfred. This means that everything stays nice and tidy.

+Oh, and you can `brew cask install alfred` too! Not bad, eh?
