+The ``target`` option controls if the editor is compiled and debug flags are used.
+Optimization levels (``optimize``) and whether each build contains debug symbols
+(``debug_symbols``) is controlled separately from the target. Each mode means:
 
--  ``target=editor``: Build with editor, optimized, with debugging code (defines: ``TOOLS_ENABLED``, ``DEBUG_ENABLED``, ``-O2``/``/O2``)
--  ``target=template_debug``: Build with C++ debugging symbols (defines: ``DEBUG_ENABLED``, ``-O2``/``/O2``)
--  ``target=template_release``: Build without symbols (defines: ``-O3``/``/O2``)
+-  ``target=editor``: Build an editor binary (defines ``TOOLS_ENABLED`` and ``DEBUG_ENABLED``)
+-  ``target=template_debug``: Build a debug export template (defines ``DEBUG_ENABLED``)
+-  ``target=template_release``: Build a release export template
 
 The editor is enabled by default in all PC targets (Linux, Windows, macOS),
 disabled for everything else. Disabling the editor produces a binary that can
 run projects but does not include the editor or the Project Manager.
