+=== Bindings ===
+  * Habitat binding is how services discover each other
+  * Binds are implemented as a contract between consumer plan and provider plan
+  * Relationship is expressed in the plan
+  * Habitat Supervisor starts services only after all required binds are met
+== Consumers ==
+  * [[https://www.habitat.sh/docs/reference/#pkg_binds|pkg_binds]]
+    * Sets a required bind
+    * Service won't start without it
+    * Supervisor will wait forever for the other service before starting the consumer
+  * [[https://www.habitat.sh/docs/reference/#pkg_binds_optional|pkg_binds_optional]]
+    * Supervisor will look for a provider but own't prevent consumer startup if it can't satisfy the bind
+== Providers ==
+  * [[https://www.habitat.sh/docs/reference/#pkg_exports|pkg_exports]]
+    * Exposes a service to Habitat Supervisor
+    * Provides values for attributes that the binding expects
