-    Two examples are:
-    - Country.from_alpha_2("DE")
-    - Country.from_alpha_3("DEU")
+    This class provides multiple ways to look up countries:
+    - By 2-letter alpha-2 code (e.g., "DE" for Germany)
+    - By 3-letter alpha-3 code (e.g., "DEU" for Germany)
+    - By fuzzy search of country names
+    - Directly from pycountry Country objects
 
-    If the country couldn't be found, it raises a ValueError, or creates an empty object.
-    Empty objects return for every attribute None
-    """  
+    The class supports optional fallback behavior when a country isn't found,
+    configurable through the module's config settings.

+    >>> Country("Germany")  # Automatic detection
+    >>> Country.search("Germany")
+    >>> 
+    >>> Country.from_alpha_2("DE")  # Germany by alpha-2 code
+    >>> Country.from_alpha_3("DEU")  # Germany by alpha-3 code
+    >>> Country.from_fuzzy("Germany")  # Germany by name search

+        EmptyCountryException: If the country cannot be found and no fallback is configured.  
+    
+    If you don't want to raise an Exception if no country you can create a Country instance by the following methods:  
+    - Country.search: returns None if nothing is found  
+    - initialize EmptyCountry instead: gives you either a Country instance or an EmptyCountry instance
