+zx-brainfuck
+=========
+
+ZX-Brainfuck é um interpretador de [Brainfuck] em Assembly no ZX Spectrum.
+
+Requisitos
+-----------
+
+O unico realmente necessário é o Assembler, mas para ver o resultado convem tambem ter um emulador, os verdadeiros podem converter o ficheiro [tap] para audio, passar para um leitor de mp3 e ligar a um Spectrum real :-D
+
+* [Pasmo] - Assembler de Z80, é Open Source e Cross Platform
+* [ZX Spin] - Emulador de ZX Spectrum para Windows que inclui um Debugger
+
+Instalação
+--------------
+
+```sh
+git clone https://github.com/falsovsky/z80.git
+cd z80/zx-brainfuck
+pasmo -v --tapbas --err main.asm main.tap
+```
+
+Licença
+----
