+## Build Flags
+
+There are several useful build flags you can add to a build to affect how it works. A full list can be found in `project.hxp`, but here's information on some of them:
+
+- `-debug` to build the game in debug mode. This automatically enables several useful debug features.
+    - This includes enabling in-game debug functions, disables compile-time optimizations, enabling asset redirection (see below), and enabling the VSCode debug server (which can slow the game on some machines but allows for powerful debugging through breakpoints).
+    - `-DGITHUB_BUILD` will enable in-game debug functions (such as the ability to time travel in a song by pressing `PgUp`/`PgDn`), without enabling the other stuff
+- `-DFEATURE_POLYMOD_MODS` or `-DNO_FEATURE_POLYMOD_MODS` to forcibly enable or disable modding support.
+- `-DREDIRECT_ASSETS_FOLDER` or `-DNO_REDIRECT_ASSETS_FOLDER` to forcibly enable or disable asset redirection.
+    - This feature causes the game to load exported assets from the project's assets folder rather than the exported one. Great for fast iteration, but the game
+- `-DFEATURE_DISCORD_RPC` or `-DNO_FEATURE_DISCORD_RPC` to forcibly enable or disable support for Discord Rich Presence.
+- `-DFEATURE_VIDEO_PLAYBACK` or `-DNO_FEATURE_VIDEO_PLAYBACK` to forcibly enable or disable video cutscene support.
+- `-DFEATURE_CHART_EDITOR` or `-DNO_FEATURE_CHART_EDITOR` to forcibly enable or disable the chart editor in the Debug menu.
+- `-DFEATURE_STAGE_EDITOR` to forcibly enable the experimental stage editor.
+- `-DFEATURE_GHOST_TAPPING` to forcibly enable an experimental gameplay change to the anti-mash system.
