 Most likely you want to use [haskell-language-server](/~https://github.com/haskell/haskell-language-server) for smart IDE features like autocompletion and jump-to-symbol. This is not working with IHP yet. [There is an active issue to implement support for this.](/~https://github.com/digitallyinduced/ihp/issues/190)

+## Using VSCode on Windows with Windows Subsystem for Linux
+
+It is important to not access the files within the WSL from Windows itself (however, the other way around is ok). You can seamlessly (including autosave) work on your projects within WSL from VS Code in Windows by adding the `Remote WSL` extension from Microsoft.

+While the default forms layout is vertical with one field per line, it is easy to change. Bootstrap's excellent [forms documentation](https://getbootstrap.com/docs/4.4/components/forms/) shows how.

 ## Working with other CSS Frameworks
 
 TODO: This section still has to be implemented. The gist of how rendering can be completely overriden to support a different layout or CSS framework can be found in the implementation of [horizontalFormFor](https://ihp.digitallyinduced.com/api-docs/IHP-View-Form.html#v:horizontalFormFor) (renders a bootstrap 4 form in a horizontal way).
