 * Update the package **description**: Why is the package being deprecated?
-* Add a **[dependency](http://docs.nuget.org/docs/reference/nuspec-reference#Specifying_Dependencies) on the other package** (if the package is being superseded).
-* **Remove all files** except the `.nuspec` from the Chocolatey Package.
-* Replace `<files>...</files>` section in `.nuspec` with `<files />` tag to prevent any file from being included with the package.
