 ## Building
 
 POSIX systems are supported, as are some Rockbox targets.

+## Technical Details
+
+The program consists of four parts: the interpreter, compiler, bytecode interpreter, and C transcompiler.
+
+### Interpreter
+
+Executes ducky directly.
+
+
+### Bytecode Compiler
+
+Compiles ducky to a stack-machine based bytecode.
+
+### Bytecode Interpreter
+
+Executes the bytecode generated by the bytecode compiler.
+
+### C Transcompiler
+
+Translates bytecode generated by the bytecode compiler into C.
+Depends on labels as values, which is a GCC extension.
+
 ## Future Directions
 
-   - Compile to C?
    - Refactor code
+   - Input
    - Add more builtins
    - Arrays?
    - Functions?
