+# Capabilities Catalog
+
+A `Capability` is a specific feature or API that a `Topology` offers. `Interpret` logic uses these capabilities to execute a `Score`.
+
+This list is primarily for developers **writing new Topologies or Scores**. As a user, you just need to know that the `Topology` you pick (like `K8sAnywhereTopology`) provides the capabilities your `Scores` (like `ApplicationScore`) need.
