+[Effect-TS](https://effect.website/) integration for React 19+ that allows you to write function components using Effect generators.
 
 This library is in early development. While it is (almost) feature complete and mostly usable, expect bugs and quirks. Things are still being ironed out, so ideas and criticisms are more than welcome.
 
 Documentation is currently being written. In the meantime, you can take a look at the `packages/example` directory.
 
 ## Peer dependencies
-- `effect` 3.19+
+- `effect` 3.15+
-- `react` & `@types/react` 19.2+
+- `react` & `@types/react` 19+
 
 ## Known issues
-- React Refresh doesn't work for Effect FC's yet. Page reload is required to view changes. Regular React components are unaffected.
+- React Refresh replacement doesn't work for Effect FC's yet. Page reload is required to view changes. Regular React components are unaffected.
