# Gamnit display implementation for Android
#
-# Generated APK files require OpenGL ES 2.0.
+# Gamnit apps on Android require OpenGL ES 3.0 because, even if it uses only
+# the OpenGL ES 2.0 API, the default shaders have more than 8 vertex attributes.
+# OpenGL ES 3.0 ensures at least 8 vertex attributes, while 2.0 ensures only 4.
#
-# This modules uses `android::native_app_glue` and the Android NDK.
+# This module relies on `android::native_app_glue` and the Android NDK.
