+  Retrieves a value from the cache if it exists, or executes a function to create and store it.
+
+  This is a convenience function implementing the common "get or create" pattern for caches.
+  It attempts to fetch a value from the cache first, and only if the value doesn't exist,
   it will execute the provided function to generate the value and store it in the cache.
-  
+
   ## Parameters
-  
+
   - `cache` - The cache module to use (must implement the Cache behaviour)
   - `key` - The key to look up or create
   - `fnc` - A function that returns `{:ok, value}` or `{:error, reason}`
-  
+
   ## Returns
-  
+
   - `{:ok, value}` - The value from cache or newly created value
   - `{:error, reason}` - If an error occurred during retrieval or creation
-  
+
   ## Examples
-
