## What it is
An open-source series of blog posts (also available as a PDF book) that teaches x86_64 assembly programming on GNU Linux. It covers processor architecture, stack and heap memory, system calls, macros, floating-point arithmetic, and calling assembly from C.

## Use cases
- learn x86_64 assembly from scratch
- understand how programs run at the low level
- learn how system calls work on Linux
- understand stack and heap memory layout
- learn to call assembly code from C
- study x86_64 processor architecture concepts
- download a free assembly programming book as PDF

## When to choose
- you want a free, hands-on introduction to x86_64 assembly on Linux
- you already know a high-level language and want to go low-level
- you prefer learning through runnable examples with CI-verified code
- you want a structured series from basics to C interop

## When to avoid
- you need ARM64 or other architectures (only planned, not covered)
- you are a complete beginner with no programming background
- you need a comprehensive reference manual rather than a tutorial
- you need Windows or macOS assembly coverage

## Facets
- artifact type: learning-resource
- maturity: stable
- function: documentation, developer-tools
- domain: tutorials, operating-systems, programming-languages, education
- platform: cli
- tags: assembly, x86-64, book, low-level-programming, system-calls, nasm, linux
