 # useFunnel
 
-Manage your funnels declaratively and explicitly.
+**Freedom From Details** : Instead of relying directly on the router, it provides instructions on where to route.
+
+**Flexible Customization** : We advocate funnel management via queryString, but you can also implement it another way via useCoreFunnel.
+
+**Nested funnel support** : Managing nested funnels is one of the biggest headaches. We offer a way to deal with this
+
+**Guard support** : Provides a way to block access by malicious users.
+
+**Separate declaration and use of funnels** : For flexible design, we separate the part that defines the funnel from the part that uses it.
