 ## Use cases
 
+### Ensuring consistency in module version retrieval
+
+When working in environments that prioritize consistency and reliability, configuring Athens with the `strict` mode guarantees a dependable and predictable module version resolution mechanism.
+
+Using the `strict` mode, Athens merges module versions from its storage and the VCS, while ensuring that any failure in either source results in a failure response.
+
+Choose Athens' `strict` network mode for a reliable and consistent approach to module version retrieval.

 ### Fetching modules for offline environments
 
-When working in offline environments with private networks lacking direct internet access, Athens' offline mode can be useful. For example, you can [pre-download](/configuration/prefill-disk-cache/) modules using Athens from a machine with internet access. Subsequently, the pre-downloaded modules are accessible within the offline network through Athens, facilitating development and build without requiring an active internet connection.

+### Ensuring availability of modules versions
+
+In certain situations, the stability or availability of the VCS may vary. To mitigate potential disruptions, Athens offers the `fallback` mode. If the VCS encounters issues or fails to respond, Athens falls back to serving modules from its storage to ensure continued availability.
+
+However, using the `fallback` mode may result in inconsistent results. Athens will provide the available versions at the time of the request, which may differ from the latest versions in the VCS.
