 ```
 
-This plugin integrates with [nvim-dap](https://github.com/mfussenegger/nvim-dap) to provide debug capabilities.
-Currently if `debugger.enabled` is set to `true` in the user's config **it will expect `nvim-dap` to be installed**.
-If `dap` is this plugin will use `flutter` or `dart` native debugger to debug your project.
-
-You can use the `debugger.register_configurations` to register custom runner configuration (for example for different targets or flavor).
-If your flutter repo contains launch configurations in `.vscode/launch.json` you can use them via this config :
-
-```lua
-  debugger = {
-    enabled = true,
-    register_configurations = function(_)
-      require("dap").configurations.dart = {}
-      require("dap.ext.vscode").load_launchjs()
-    end,
-  },
-```
+This plugin integrates with [nvim-dap](https://github.com/mfussenegger/nvim-dap) to provide debug capabilities for Flutter and Dart applications.
 
-Since there is an overlap between this plugin's log buffer and the repl buffer when running via dap, you may use the `dev_log.enabled` configuration option if you want.
+The plugin will automatically set up `nvim-dap` for Flutter/Dart debugging.
