IAF Help

The original IAF HTML documentation is not distributed with this extension. To enable full help pages, run IAF: Select Help Folder from the Command Palette and select the IAFHelp directory from your local IAF installation. The selected path is saved in your global VS Code settings.

The extension can also find an IAFHelp directory in the current workspace or its parent directory.
