 What's different in the library:
-- Reagent was replaced by Siagent.
+- Reagent was removed.
 - Some small changes were needed in `re-frame.interop` to making it work with Signaali.
 - `re-frame.interop/after-render` won't work exactly in the same way, but most apps don't use it.

 In your `deps.edn`, replace the re-frame dependencies with:
 
 ```clojure

-This lib should work for you if:
-- All the Reagent features your Reagent components (if any) are using are supported by [Siagent](https://github.com/metosin/siagent).
-- Your codebase is not directly using the low level implementation of Reagent, e.g. the `reagent.ratom/RAtom` type.
+This lib should work for you if you don't use Reagent in your code base.
