-**Default:** `settings.DEBUG`
+**Default:** `settings.py:DEBUG`
 
 Recheck the filesystem to see if any files have changed before responding.

 ## `SERVESTATIC_USE_FINDERS`
 
-**Default:** `settings.DEBUG`
+**Default:** `settings.py:DEBUG`
 
 Instead of only picking up files collected into `STATIC_ROOT`, find and serve files in their original directories using Django's "finders" API. This is useful in development where it matches the behaviour of the old `runserver` command. It's also possible to use this setting in production, avoiding the need to run the `collectstatic` command during the build, so long as you do not wish to use any of the caching and compression features provided by the storage backends.
