+Runtime vs compile-time filters
+
+  The above filters (1..4) all apply at RUNTIME ("rt").
+  This is typically what you want, since it allows you to freely adjust filtering
+  (making it less OR MORE permissive) through later API calls like `set-min-level!`.
+
+  As an advanced option, you can instead/additionally ELIDE (entirely omit) filtered
+  callsites at COMPILE-TIME ("ct") by replacing "rt"->"ct" / "RT"->"CT" in the config
+  ids above. Compile-time filters CANNOT be made MORE permissive at runtime.
 
 Tips:
 
-  - The above ids are for runtime filters (the most common).
-    For compile-time filters, change `rt`->`ct` / `RT`->`CT`.
-
-  - The above ids will affect both Clj AND Cljs.
+  - The above config ids will affect both Clj AND Cljs.
     For platform-specific filters, use
       ".clj"  / "_CLJ"  or
       ".cljs" / "_CLJS" suffixes instead.
+      e.g. "taoensso.telemere.rt-min-level.cljs".
 
   - To get the right edn syntax, first set your runtime filters using the
     standard utils (`set-min-level!`, etc.). Then call `get-filters` and
