Certainly! Here's an example "hello world" program in x86 64-bit assembly that should be relatively easy to read:

section .data
    message db 'Hello, world!',0   ; define the message to be printed

section .text
    global _start

_start:
    ; write the message to standard output
    mov rax, 1         ; system call number for "write"
    mov rdi, 1         ; file descriptor 1 is standard output
    mov rsi, message   ; address of the message to be printed
    mov rdx, 13        ; message length
    syscall

    ; exit the program
    mov rax, 60        ; system call number for "exit"
    xor rdi, rdi       ; exit status code (0 for success)
    syscall


The first section, .data, defines the string to be printed, using the db (define byte) directive to create an array of characters terminated by a null byte (0).

The second section, .text, contains the actual code of the program. The global _start directive tells the linker that _start is the entry point of the program.

The _start label marks the beginning of the program. The first set of instructions use the mov (move) instruction to set up the arguments for the write system call, which will print the message to standard output. Specifically, rax is set to the system call number for write, rdi is set to 1 (the file descriptor for standard output), rsi is set to the address of the message string, and rdx is set to the length of the message (in bytes).

After the write system call completes, the program uses another set of mov instructions to set up the arguments for the exit system call. Specifically, rax is set to the system call number for exit, and rdi is set to 0 (the exit status code for success).

Finally, the syscall instruction is used to make each system call. This transfers control to the kernel, which carries out the requested operation (in this case, printing the message and exiting the program).
