+### Site generate with collection
+
+On the site generator configuration: we want to add an option/field, where
+a user can provide collection file as configuration.
+
+During site generation, we want the generator to take this into consideration
+and based on this we also want to the site generator to invoke the collection
+building happening.
+
+In the collection interface, we also want to support configuration options,
+instead of passing around we also want to be specified in form of data filed
+and use that one to pass it down to the metanorma xml
+
+### Todos
+
+- [ ] Add support for collection option parsing
+- [ ] Adopt the field changes for the collection
+- [ ] Define collection config in the generator
+- [ ] Invoke the parsing from the site generator
+- [ ] Adopt this interface in collection, maybe?
