 ## Ejection
 
+You **do not** need to eject your project for you to use `cra-build-watch`.
+
 This tool handles ejected projects but it assumes you did not modify your `webpack.config.js` file, `paths.js` and `env.js` utils. If you did I cannot guarantee that this tool will work.
 
 # Why do I need this?
