+### Minikin Style Guide
+
+The C++ style in Minikin follows Android Framework C++ Code Style Guide except for following rules:
+
+ * Order of include
+
+ In dir/foo.cc or dir/foo_test.cc, whose main purpose is to implement or test the stuff in
+ dir2/foo2.h, order your includes as follows:
+
+ 1. dir2/foo.h
+ 2. A blank line
+ 3. C system files
+ 4. C++ system files
+ 5. A blank line
+ 6. Other libraries' files
+ 7. A blank line
+ 8. Minikin public files
+ 9. A blank line
+ 10. Minikin private files
+
+ For example,
+ ```
+ #include "minikin/Layout.h" // The corresponding header file.
+
+ #include <math.h> // C system header files.
+ #include <string> // C++ system header files.
+
+ #include <hb.h> // Other library, HarfBuzz, header file.
+ #include <log/log.h> // Other library, Android, header file.
+ #include <unicode/ubidi.h> // Other library, ICU, header file.
+
+ #include "minikin/Emoji.h" // The minikin public header file.
+ #include "HbFontCache.h" // The minikin private header file.
+ ```
+
+ * "<>" vs ""
+
+ * `#include <...>` should be used for non local library files.
+ * `#include "..."` should be used for minikin header files.
