+# Coolify Backup Daemon
+
+This is a bare-metal backup daemon written in pure x86_64 NASM assembly with zero libc dependency, direct Linux syscalls, and a 64KB constraint.
+
+## Features
+
+* Database dump module
+* Compression module using LZ4
+* Encryption module using AES-256-GCM
+* Chunking module
+* Upload module using HTTP/1.1
+
+## Usage
+
+1. Clone this repository
+2. Run `nasm -f elf32 daemon.asm` to assemble the daemon
+3. Run `ld -m elf_i386 -o daemon daemon.o` to link the daemon
+4. Run `./daemon` to run the daemon
+
