 You can use the VS Code `Issue Reporter` to report issues. Just click on the `Help -> Report Issue` menu, select `An extension` for the `File on` entry and `Language Support for Ada` for the extension name. Put as many information you can in the description, like steps to reproduce, stacktraces or system information (VS Code automatically includes it by default). This will create a GitHub issue in the [Ada Language Server](https://github.com/AdaCore/ada_language_server/) repository.
 
+ALS log files can be found under the `~/.als` directory (`%USERPROFILE%/.als` on Windows). Feel free to attach them on the issues, it helps a lot for further investigation, specially when the `ALS.IN` and `ALS.OUT` traces are enabled (more info about traces configuration can be found [here](doc/traces.md).)
