 * `[:auth, :enforce_oauth_admin_scope_usage]` — OAuth admin scope requirement toggle.
     If `true`, admin actions explicitly demand admin OAuth scope(s) presence in OAuth token (client app must support admin scopes).
     If `false` and token doesn't have admin scope(s), `is_admin` user flag grants access to admin-specific actions.

 ### Update config settings
 
-Updating config settings only works with `:pleroma => :instance => :dynamic_configuration` setting to `true`.
-Module name can be passed as string, which starts with `Pleroma`, e.g. `"Pleroma.Upload"`.
-Atom keys and values can be passed with `:` in the beginning, e.g. `":upload"`.
-Tuples can be passed as `{"tuple": ["first_val", Pleroma.Module, []]}`.
-`{"tuple": ["some_string", "Pleroma.Some.Module", []]}` will be converted to `{"some_string", Pleroma.Some.Module, []}`.
-Keywords can be passed as lists with 2 child tuples, e.g.
-`[{"tuple": ["first_val", Pleroma.Module]}, {"tuple": ["second_val", true]}]`.
+**Only works when configuration from database is enabled.**
+
+Some modifications are necessary to save the config settings correctly:
 
-If value contains list of settings `[subkey: val1, subkey2: val2, subkey3: val3]`, it's possible to remove only subkeys instead of all settings passing `subkeys` parameter. E.g.:
-{"group": "pleroma", "key": "some_key", "delete": "true", "subkeys": [":subkey", ":subkey3"]}.
+- strings which start with `Pleroma.`, `Phoenix.`, `Tesla.` or strings like `Oban`, `Ueberauth` will be converted to modules;
+```
+"Pleroma.Upload" -> Pleroma.Upload
+"Oban" -> Oban
+```
+- strings starting with `:` will be converted to atoms;
+```
+":pleroma" -> :pleroma
+```
+- objects with `tuple` key and array value will be converted to tuples;
+```
+{"tuple": ["string", "Pleroma.Upload", []]} -> {"string", Pleroma.Upload, []}
+```
+- arrays with *tuple objects* will be converted to keywords;
+```
+[{"tuple": [":key1", "value"]}, {"tuple": [":key2", "value"]}] -> [key1: "value", key2: "value"]

-Compile time settings (need instance reboot):
