+# OpenWrt Reticulum Package Builder 📡
+
+GitHub workflow for cross-compiling [Reticulum Network Stack (RNS)](https://github.com/markqvist/Reticulum) packages for OpenWrt. Based on [openwrt/gh-action-sdk](https://github.com/openwrt/gh-action-sdk).
+
+> **Note**: This is an experimental project currently under active development. The build process and package structure are still being refined and may change significantly. Not recommended for production use yet!
+
+## Overview 📖
+
+This repository provides GitHub Actions workflows for building OpenWrt packages defined in the [feed-reticulum](https://github.com/gretel/feed-reticulum) repository. While the feed contains the package definitions (Makefiles, patches, and configurations), this workflow handles the automated cross-compilation process.
+
+### Repository Relationship
+- **feed-reticulum**: Contains OpenWrt package definitions for RNS
+- **This repository**: Provides automation to build those packages for different architectures
+
+## Features ✨
+
+- Cross-compiles RNS packages for OpenWrt targets
+- Uses official OpenWrt SDK containers
+- Build artifact collection and release management
+- Package signing support
+
+## How it Works 🔄
+
+1. The workflow fetches the official OpenWrt SDK container for each target architecture
+2. It adds our custom feed (`feed-reticulum`) to the SDK
+3. The packages (`rns` and `lxmf`) are then built using the SDK
+4. Built packages are collected and published as artifacts
+
+## Supported Platforms 🎯
+
+This workflow builds `rns` and `lxmf` packages for:
+
+| Architecture | Example Devices |
+|--------------|----------------|
+| `aarch64_cortex-a53` | GL.iNet MT3000 (Beryl AX), Raspberry Pi 4/Zero 2, MediaTek MT7981/MT7622 |
+| `arm_arm1176jzf-s_vfp` | Raspberry Pi Zero (1st gen) |
+| `mips_24kc` | GL.iNet AR750S (Slate), GL.iNet AR300M, Most Atheros AR71xx/AR72xx/AR93xx |
+| `x86_64` | Generic x86_64 devices, Virtual Machines |
+
+## Usage 🚀
+
+Create a workflow file (e.g. `.github/workflows/build.yml`):
+
+```yaml
+name: Build OpenWrt Packages
+
+on:
+  push:
+    branches: [ main ]
+    tags: ["[0-9]+.[0-9]+.[0-9]+*"]
+  pull_request:
+  workflow_dispatch:
+
+env:
+  PACKAGES: rns lxmf
+  EXTRA_FEEDS: >-
+    src-git|reticulum|https://github.com/gretel/feed-reticulum.git
+
+jobs:
+  build:
+    # ... rest of workflow configuration
+```
+
+## Configuration ⚙️
+
+### Environment Variables
+
+| Variable | Description | Default |
+|----------|-------------|---------|
+| `PACKAGES` | Space-separated list (`rns lxmf`) | Required |
+| `EXTRA_FEEDS` | Feed URL (`src-git\|reticulum\|url`) | Required |
+| `V` | Build verbosity ('', 's', 'sc') | '' |
+| `PRIVATE_KEY` | Package signing key | Repository Secret |
+| `INDEX` | Generate package index (0/1) | 0 |
+
+## Artifacts 📦
+
+The workflow produces:
+- Built packages (`.ipk` format)
+- Build logs (if enabled)
+- Package index (if enabled)
+
+All artifacts are:
+- Collected from `/artifacts` directory
+- Uploaded to GitHub Actions artifacts
+- Published to GitHub Releases for tagged commits
+
+## Requirements 📋
+
+- GitHub Actions runner with Docker support
+- OpenWrt-compatible package source code
+- Valid package Makefiles in feed
+- Package signing key (optional)
+
+## Development Setup 🛠️
+
+For local development and testing, refer to the [feed-reticulum](https://github.com/gretel/feed-reticulum) repository, which contains detailed instructions for:
+- Setting up the OpenWrt build environment
+- Installing required dependencies
+- Building packages locally
+- Configuration and usage guides
