+How to build Module for Platform
+- It is only for modules are needed to using Android build system.
+- Please check its own install information under its folder for other module.
+
+[Step to build]
+1. Get android open source.
+    : version info - Android 13.0
+    ( Download site : http://source.android.com )
+
+2. Copy module that you want to build - to original android open source
+   If same module exist in android open source, you should replace it. (no overwrite)
+   
+  # It is possible to build all modules at once.
+  
+3. You should add module name to 'PRODUCT_PACKAGES' in 'build/make/target/product/base_system.mk' as following case.
+	case 1) libexifa : should add 'libexifa.camera.samsung' to PRODUCT_PACKAGES
+	case 2) libjpega : should add 'libjpega.camera.samsung' to PRODUCT_PACKAGES
+	case 3) keyutils : should add 'libknox_keyutils' to PRODUCT_PACKAGES
+	
+
+ex.) [build/make/target/product/base_system.mk] - add all module name for case 1 ~ 3 at once
+    
+# libexifa
+PRODUCT_PACKAGES += \
+    libexifa.camera.samsung
+    
+# libjpega
+PRODUCT_PACKAGES += \
+    libjpega.camera.samsung
+    
+# KeyUtils
+PRODUCT_PACKAGES += \
+    libknox_keyutils
+   
+4. excute build command
+   ./build_64bit.sh
+
