+# Assembleur
+
+## Usage
+
+```bash
+./Assembleur [--help] [--reversed] [--version] [--output file] [--format type] file
+```
+
+There are 3 format types :
+ - "int" : 32 bits integers are written. Exemple : `10878976`
+ - "binint" : bits are written. Exemple : `00000000 10100110 00000000 00000000`
+ - "bin" : the file is written in pure binary
+ - "logisim" (default) : the file is written in binary for use in LogiSim
+
+## Exemple
+
+```assembly
+operations:
+	add R1 R2 R3
+	sub R1 R2 #69
+	and R0 R6 R3
+	xor R1 R2 R3
+	or R1 R7 R3
+	sl R5 R2 #10
+	sr R1 R2 R3
+	mult R1 R1 R3
+io:
+	str R1 R2 R3
+	ld R1 R2 R3
+sauts:
+	jmp controle
+	jequ R1 R2 io
+	jneq R1 R2 sauts
+	jsup R1 R2 operations
+	jinf R1 R2 controle
+controle:
+	call io
+	ret
