Any tutorials out there for this?

I want to learn about dll/exe assembly and decompiling and understand it, I was wondering if there are any good tutorials out there that can get me started. For Example

.text:0000000010005400 push rbp
.text:0000000010005401 push rdi
.text:0000000010005402 push rsi
.text:0000000010005403 push rbx
.text:0000000010005404 sub rsp, 0x38
.text:0000000010005408 cmp edx, 0x1
.text:000000001000540b je 0x10005420
.text:000000001000540d
.text:000000001000540d 0x1000540d:
.text:000000001000540d mov eax, 0x1
.text:0000000010005412
.text:0000000010005412 0x10005412:
.text:0000000010005412 add rsp, 0x38
.text:0000000010005416 pop rbx
.text:0000000010005417 pop rsi
.text:0000000010005418 pop rdi
.text:0000000010005419 pop rbp
.text:000000001000541a ret
.text:000000001000541b nop dword ptr [rax+rax]

what kind of tutorial can show me how to read something like that properly and try to make sense of it

Thanks in Advance
