-## Motivation
+## What’s lacking in the original `kubectl-explain`?
 
-- `kubectl explain` needs knowing in advance the resources name/fields.
-- `kubectl explain` needs typing the accurate path to the resource name/field, which is a tedious and typo-prone.

+## Example Usage
 
-Examples:
-
-# Fuzzy-find the field to explain from all API resources.
+```bash
+# Fuzzy-find a resource, then a field to explain
 kubectl explore
 
-# Fuzzy-find the field to explain from pod.
+# Fuzzy-find from all fields of a specific resource.
 kubectl explore pod
+kubectl explore sts
 
-# Fuzzy-find the field to explain from fields matching the regex.
-kubectl explore pod.*node
-kubectl explore spec.*containers
-kubectl explore lifecycle
+# Fuzzy-find from fields that a given regex matches.
 kubectl explore sts.*Account
