 # scala-js-env-playwright
-A JavaScript environment for Scala.js (a JSEnv) running playwright
+A JavaScript environment for Scala.js (a JSEnv) running playwright. It is only build for Scala 3 (supported by Mill and SBT 2.x)
 ## Requirements
 Playwright needs certain system dependencies [read the docs](https://playwright.dev/docs/browsers#install-system-dependencies)
 
 TLDR -> `npx playwright install-deps`

 ## Avoid trouble
 * This is a very early version. It may not work for all projects. It is tested on chrome/chromium and firefox.
 * Few test cases are failing on webkit. Keep a watch on this space for updates.
 * It works only with Scala.js 1.x
 * Make sure the project is set up to use ModuleKind.ESModule in the Scala.js project.
+  * SBT 2.x
   ```scala
     // For Scala.js 1.x
     scalaJSLinkerConfig ~= { _.withModuleKind(ModuleKind.ESModule) }

+  ```scala

 * Some projects which may need to use both Selenium and Playwright.
