+Note: Windy is the default example. Harfbuzz support works with Siwin, Surfer or other windowing libraries.
 
 Then compile with the Harfbuzzy text backend:

 ```sh
 nim r -d:figdrawTextBackend=harfbuzzy examples/windy_text_shaping_demo.nim

 For an example or app that should always use Harfbuzzy, put the backend switch
 in a sibling `.nims` file:
