+Tracking page for documentation and example code Style Guide discussion.
+
+
+### Elements discussed and decided:
+
+Use class arguments instead of `class Meta`.
+
+Example:
+Instead of:
+```
+    class Human(graphene.ObjectType):
+        class Meta:
+            interfaces = (Character, )
+
+        starships = graphene.List(Starship)
+        home_planet = graphene.String()
+```
+
+Use:
+```
+    class Human(graphene.ObjectType, interfaces = (Character, )):
+        starships = graphene.List(Starship)
+        home_planet = graphene.String()
+```
+
+Use f-strings in place of `.format(...)`.
+
+### Open for discussion:
+
+Using `root` instead of `self` or `_` in resolver definitions.
+
+`@staticmethod`?
