 ## Abstract
 
-Xbyak is a C++ header library that enables dynamically to assemble x86(IA32), x64(AMD64, x86-64) mnemonic.
+Xbyak is a C++ header-only library that enables dynamic assembly of x86/x64 instructions using mnemonics.
 
-The pronunciation of Xbyak is `kəi-bja-k`.
-It is named from a Japanese word [開闢](https://translate.google.com/?hl=ja&sl=ja&tl=en&text=%E9%96%8B%E9%97%A2&op=translate), which means the beginning of the world.
+The pronunciation of Xbyak is `/kʌɪbjæk/` (kai-byak).
 
-## Feature
+The name is derived from the Japanese word [開闢](https://translate.google.com/?hl=ja&sl=ja&tl=en&text=%E9%96%8B%E9%97%A2&op=translate) (kaibyaku), which means "the beginning of the world" or "creation".

 - WAITPKG instructions (tpause, umonitor, umwait) are supported.
 - MmapAllocator supports memfd with user-defined strings. see sample/memfd.cpp
-- strictly check address offset disp32 in a signed 32-bit integer. e.g., `ptr[(void*)0xffffffff]` causes an error.
-  - define `XBYAK_OLD_DISP_CHECK` if you need an old check, but the option will be remoevd.
-- add `jmp(mem, T_FAR)`, `call(mem, T_FAR)` `retf()` for far absolute indirect jump.
-- vnni instructions such as vpdpbusd supports vex encoding.
-- (break backward compatibility) `push(byte, imm)` (resp. `push(word, imm)`) forces to cast `imm` to 8(resp. 16) bit.
