 First note that every plugin has `apply false` except for `com.diffplug.blowdryerSetup`. That is on purpose. We need to apply `blowdryerSetup` so that we can use the `blowdryerSetup {}` block, and we need to do `apply false` on the other plugins because we're just putting them on the classpath, not actually using them (yet).
 
-The second thing to note is `setPluginsBlockTo { file('plugin.versions') }`.

 If you do `apply plugin: 'com.diffplug.blowdryer'` then every project gets an extension object ([code](https://github.com/diffplug/blowdryer/blob/master/src/main/java/com/diffplug/blowdryer/BlowdryerPlugin.java)) where the project field has been filled in for you, which is why we don't pass it explicitly in the examples before this section.  If you don't apply the plugin, you can still call these static methods and pass `project` explicitly for the `proj()` methods.
