 The main reference implementation is written in [ANSI C](c.md) (about 32000 LOC) and uses a register-based bytecode virtual machine for execution.
 Another notable implementation is [LuaJIT](https://luajit.org), which speeds up execution speed by JIT compiling the Lua code.
 
+## Bytecode
+`luac` can be used to compile and dump bytecode into a file. However the bytecode is not portable.
+```sh
+luac -o out source.lua
+```
+
+You can get a listing of the compiled bytecode for a Lua source file with `luac`:
+```sh
+luac -p -l -l source.lua
+```
