+### MRF policies descriptions
+
+If MRF policy depends on config, it can be added into MRF tab to adminFE by adding `config_description/0` method, which returns a map with a specific structure. See existing MRF's like `lib/pleroma/web/activity_pub/mrf/activity_expiration_policy.ex` for examples. Note that more complex inputs, like tuples or maps, may need extra changes in the adminFE and just adding it to `config_description/0` may not be enough to get these inputs working from the adminFE.
+
+Example:
+
+```elixir
+%{
+ key: :mrf_activity_expiration,
+ related_policy: "Pleroma.Web.ActivityPub.MRF.ActivityExpirationPolicy",
+ label: "MRF Activity Expiration Policy",
+ description: "Adds automatic expiration to all local activities",
+ children: [
+ %{
+ key: :days,
+ type: :integer,
+ description: "Default global expiration time for all local activities (in days)",
+ suggestions: [90, 365]
+ }
+ ]
+ }
+```
