+### Condition for loading `withCondition`
+
+For convenience, `plugin-bust` provides a `withCondition` named export
+that is a conditional plugin, an `Object` consisting of the plugin
+along with a condition method.
+
+The condition is met if both:
+1. `options.draftForHighBust` is set to `true`
+2. `measurements.highBust` is set
+
+You can use `withCondition` to conditionally load `plugin-bust`,
+or you are free to instead create and use your own condition method
+to pass along with the plugin.
