+
+`fileExists` allows you to check if a file exists under a given path, e.g. before inserting code into a template:
+
+```
+{{ if (fileExists "static/img/banner.jpg") -}}
+<img src="{{ "img/banner.jpg" | absURL }}" />
+{{- end }}
+```
+
+In the example above, a banner from the `static` folder should be shown if the given path points to an existing file.
