 repositories { maven("https://jitpack.io") }
-dependencies { debugImplementation("com.github.mohdaquib.ComposeA11yScanner:scanner-ui:<tag>") }
+dependencies { debugImplementation("com.github.mohdaquib.ComposeA11yScanner:scanner-ui:v1.0.0") }
 ```
 
 Use a debug-only dependency because the scanner is intended for development builds. `:scanner-ui` brings `:scanner-core` and `:scanner-rules` transitively.
