+Highlights and Intro:
+
+Crossplane is an advanced tool for managing infrastructure in the cloud-native ecosystem.
+Just like terraform encourages using modules for bundling related resources, crossplane offers compositions.
+Platform engineers can define their compositions and provide the Devs a simple claim api.
+Devs claim their resources and the composition takes care of the rest.
