+# Assembly x86_64 - Hello World!
+
+## Assembly Code 
+
+We're going to use vim to write our code
+    
+    
+    [ 192.168.0.18/24 ] [ /dev/pts/88 ] [~/binexp/asm]
+    → vim 0.asm
+    
+    
+    
+    
+    section .data
+            text db "Hello, World!",10
+    
+    section .text
+            global _start
+    
+    _start:
+            mov rax, 1
+            mov rdi, 1
+            mov rsi, text
+            mov rdx, 14
+            syscall
+    
+            mov rax, 60
+            mov rdi, 0
+            syscall
+    
+    
+
+## Compiling 
+
+Here we're going to use nasm to compile our assembly code: 
+    
+    
+    [ 192.168.0.18/24 ] [ /dev/pts/89 ] [~/binexp/asm]
+    → nasm -f elf64 0.asm -o 0.o
+    
+    [ 192.168.0.18/24 ] [ /dev/pts/89 ] [~/binexp/asm]
+    → ls -lash
+    total 16K
+    4.0K drwxr-xr-x 2 nothing nothing 4.0K Mar  2 16:17 .
+    4.0K drwxr-xr-x 5 nothing nothing 4.0K Mar  2 16:01 ..
+    4.0K -rw-r--r-- 1 nothing nothing  179 Mar  2 16:09 0.asm
+    4.0K -rw-r--r-- 1 nothing nothing  848 Mar  2 16:17 0.o
+    
+    
+
+Now we have our 0.asm code and the 0.o object file, now we need to link it using the gnu linker (ld) to make an executable file
+    
+    
+    [ 192.168.0.18/24 ] [ /dev/pts/89 ] [~/binexp/asm]
+    → ld 0.o -o 0
+    
+    [ 192.168.0.18/24 ] [ /dev/pts/89 ] [~/binexp/asm]
+    → ls -lash
+    total 28K
+    4.0K drwxr-xr-x 2 nothing nothing 4.0K Mar  2 16:19 .
+    4.0K drwxr-xr-x 5 nothing nothing 4.0K Mar  2 16:01 ..
+     12K -rwxr-xr-x 1 nothing nothing 8.7K Mar  2 16:19 0
+    4.0K -rw-r--r-- 1 nothing nothing  179 Mar  2 16:09 0.asm
+    4.0K -rw-r--r-- 1 nothing nothing  848 Mar  2 16:17 0.o
+    
+    [ 192.168.0.18/24 ] [ /dev/pts/89 ] [~/binexp/asm]
+    → file 0
+    0: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, not stripped
+    
+    
+    
+
+and now we have our executable file called '0', we make it executable with chmod +x and then execute it:
+    
+    
+    [ 192.168.0.18/24 ] [ /dev/pts/89 ] [~/binexp/asm]
+    → chmod +x 0
+    
+    [ 192.168.0.18/24 ] [ /dev/pts/89 ] [~/binexp/asm]
+    → ./0
+    Hello, World!
+    
+    
+
+And that concludes our first assembly code! in the next part we're going to explain everything about this code [here](2.html).
