+# HXML flags
+
 Common `-D` flags that can be used with Heaps:
 
-```
+```hxml
 # flag to define the size of the window and default scene size:
 -D windowSize=800x600
 
 # define the window/process name
 -D windowTitle=My game made with Heaps.io
 
 # define the path to the game assets/resources
-# (actually not recommended, just use `-p res` insead,
-# but which demands assets to be in a directory called `res`)
--D resourcesPath=assets
-# so rather use:
--p res
+# if unset, the default path is "res"
+-D resourcesPath=res
 
 # other known flags (deprecated/legacy code)
 -D heaps_emit_tile_buffering
 
 ```
