+# Nix Deployment Quick Reference
+
+## TL;DR
+
+```bash
+# Just run it - zero configuration needed!
+nix run .#gitea-mirror
+```
+
+Secrets auto-generate, database auto-initializes, and the web UI starts at http://localhost:4321.
+
+---
+
+## Installation Options
+
+### 1. Run Without Installing
+```bash
+nix run .#gitea-mirror
+```
+
+### 2. Install to Profile
+```bash
+nix profile install .#gitea-mirror
+gitea-mirror
+```
+
+### 3. NixOS System Service
+```nix
+# configuration.nix
+{
+  inputs.gitea-mirror.url = "github:RayLabsHQ/gitea-mirror";
+
+  services.gitea-mirror = {
+    enable = true;
+    betterAuthUrl = "https://mirror.example.com";  # For production
+    openFirewall = true;
+  };
+}
+```
+
+### 4. Development
+```bash
+nix develop
+# or
+direnv allow
+```
+
+---
+
+## What Gets Auto-Generated?
+
+On first run, the wrapper automatically:
+
+1. Creates `~/.local/share/gitea-mirror/` (or `$DATA_DIR`)
+2. Generates `BETTER_AUTH_SECRET` → `.better_auth_secret`
+3. Generates `ENCRYPTION_SECRET` → `.encryption_secret`
+4. Initializes SQLite database
+5. Runs startup recovery and repair scripts
+6. Starts the application
+
+---
+
+## Key Commands
+
+```bash
+# Database management
+gitea-mirror-db init      # Initialize database
+gitea-mirror-db check     # Health check
+gitea-mirror-db fix       # Fix issues
+
+# Development
+nix develop               # Enter dev shell
+nix build                 # Build package
+nix flake check           # Validate flake
+```
+
+---
+
+## Environment Variables
+
+All vars from `docker-compose.alt.yml` are supported:
+
+```bash
+DATA_DIR="$HOME/.local/share/gitea-mirror"
+PORT=4321
+HOST="0.0.0.0"
+BETTER_AUTH_URL="http://localhost:4321"
+
+# Secrets (auto-generated if not set)
+BETTER_AUTH_SECRET=auto-generated
+ENCRYPTION_SECRET=auto-generated
+
+# Concurrency (for perfect ordering, set both to 1)
+MIRROR_ISSUE_CONCURRENCY=3
+MIRROR_PULL_REQUEST_CONCURRENCY=5
+```
+
+---
+
+## NixOS Module Options
+
+```nix
+services.gitea-mirror = {
+  enable = true;
+  package = ...;                        # Override package
+  dataDir = "/var/lib/gitea-mirror";   # Data location
+  user = "gitea-mirror";               # Service user
+  group = "gitea-mirror";              # Service group
+  host = "0.0.0.0";                    # Bind address
+  port = 4321;                         # Listen port
+  betterAuthUrl = "http://...";        # External URL
+  betterAuthTrustedOrigins = "...";    # CORS origins
+  mirrorIssueConcurrency = 3;          # Concurrency
+  mirrorPullRequestConcurrency = 5;    # Concurrency
+  environmentFile = null;              # Optional secrets file
+  openFirewall = true;                 # Open firewall
+};
+```
+

+
+## Comparison: Docker vs Nix
+
+| Feature | Docker | Nix |
+|---------|--------|-----|
+| **Config Required** | BETTER_AUTH_SECRET | None (auto-generated) |
+| **Startup** | `docker-compose up` | `nix run .#gitea-mirror` |
+| **Service** | Docker daemon | systemd (NixOS) |
+| **Updates** | `docker pull` | `nix flake update` |
+| **Reproducible** | Image-based | Hash-based |

+# Nix Deployment Guide
+
+This guide covers deploying Gitea Mirror using Nix flakes. The Nix deployment follows the same minimal configuration philosophy as `docker-compose.alt.yml` - secrets are auto-generated, and everything else can be configured via the web UI.
+
+## Prerequisites
+
+- Nix with flakes enabled (Nix 2.4+)
+- For NixOS module: NixOS 23.05+
+
+To enable flakes, add to `/etc/nix/nix.conf` or `~/.config/nix/nix.conf`:
+```
+experimental-features = nix-command flakes
+```
+
+## Quick Start (Zero Configuration!)
+
+### Run Immediately - No Setup Required
+
+```bash
+# Run directly from the flake
+nix run .#gitea-mirror
+
+# Or from GitHub (once published)
+nix run github:RayLabsHQ/gitea-mirror
+```
+
+That's it! On first run:
+- Secrets (`BETTER_AUTH_SECRET` and `ENCRYPTION_SECRET`) are auto-generated
+- Database is automatically created and initialized
+- Startup recovery and repair scripts run automatically
+- Access the web UI at http://localhost:4321
+
+Everything else (GitHub credentials, Gitea settings, mirror options) is configured through the web interface after signup.
+
+### Development Environment
+
+```bash
+# Enter development shell with all dependencies
+nix develop
+
+# Or use direnv for automatic environment loading
+echo "use flake" > .envrc
+direnv allow
+```
+
+### Build and Install
+
+```bash
+# Build the package
+nix build
+
+# Run the built package
+./result/bin/gitea-mirror
+
+# Install to your profile
+nix profile install .#gitea-mirror
+```
+
+## What Happens on First Run?
+
+Following the same pattern as the Docker deployment, the Nix package automatically:
+
+1. **Creates data directory**: `~/.local/share/gitea-mirror` (or `$DATA_DIR`)
+2. **Generates secrets** (stored securely in data directory):
+   - `BETTER_AUTH_SECRET` - Session authentication (32-char hex)
+   - `ENCRYPTION_SECRET` - Token encryption (48-char base64)
+3. **Initializes database**: SQLite database with Drizzle migrations
+4. **Runs startup scripts**:
+   - Environment configuration loader
+   - Crash recovery for interrupted jobs
+   - Repository status repair
+5. **Starts the application** with graceful shutdown handling
+
+## NixOS Module - Minimal Deployment
+
+### Simplest Possible Configuration
+
+Add to your NixOS configuration (`/etc/nixos/configuration.nix`):
+
+```nix
+{
+  inputs = {
+    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
+    gitea-mirror.url = "github:RayLabsHQ/gitea-mirror";
+  };
+
+  outputs = { nixpkgs, gitea-mirror, ... }: {
+    nixosConfigurations.your-hostname = nixpkgs.lib.nixosSystem {
+      system = "x86_64-linux";
+      modules = [
+        gitea-mirror.nixosModules.default
+        {
+          # That's it! Just enable the service
+          services.gitea-mirror.enable = true;
+        }
+      ];
+    };
+  };
+}
+```
+
+Apply with:
+```bash
+sudo nixos-rebuild switch
+```
+
+Access at http://localhost:4321, sign up (first user is admin), and configure everything via the web UI.
+
+### Production Configuration
+
+For production with custom domain and firewall:
+
+```nix
+{
+  services.gitea-mirror = {
+    enable = true;
+    host = "0.0.0.0";
+    port = 4321;
+    betterAuthUrl = "https://mirror.example.com";
+    betterAuthTrustedOrigins = "https://mirror.example.com";
+    openFirewall = true;
+  };
+
+  # Optional: Use with nginx reverse proxy
+  services.nginx = {
+    enable = true;
+    virtualHosts."mirror.example.com" = {
+      locations."/" = {
+        proxyPass = "http://127.0.0.1:4321";
+        proxyWebsockets = true;
+      };
+      enableACME = true;
+      forceSSL = true;
+    };
+  };
+}
+```
+
+### Advanced: Manual Secret Management
+
+If you prefer to manage secrets manually (e.g., with sops-nix or agenix):
+
+1. Create a secrets file:
+```bash
+# /var/lib/gitea-mirror/secrets.env
+BETTER_AUTH_SECRET=your-32-character-minimum-secret-key-here
+ENCRYPTION_SECRET=your-encryption-secret-here
+```
+
+2. Reference it in your configuration:
+```nix
+{
+  services.gitea-mirror = {
+    enable = true;
+    environmentFile = "/var/lib/gitea-mirror/secrets.env";
+  };
+}
+```
+
+### Full Configuration Options
+
+```nix
+{
+  services.gitea-mirror = {
+    enable = true;
+    package = gitea-mirror.packages.x86_64-linux.default;  # Override package
+    dataDir = "/var/lib/gitea-mirror";
+    user = "gitea-mirror";
+    group = "gitea-mirror";
+    host = "0.0.0.0";
+    port = 4321;
+    betterAuthUrl = "https://mirror.example.com";
+    betterAuthTrustedOrigins = "https://mirror.example.com";
+
+    # Concurrency controls (match docker-compose.alt.yml)
+    mirrorIssueConcurrency = 3;  # Set to 1 for perfect chronological order
+    mirrorPullRequestConcurrency = 5;  # Set to 1 for perfect chronological order
+
+    environmentFile = null;  # Optional secrets file
+    openFirewall = true;
+  };
+}
+```
+
+## Service Management (NixOS)
+
+```bash
+# Start the service
+sudo systemctl start gitea-mirror
+
+# Stop the service
+sudo systemctl stop gitea-mirror
+
+# Restart the service
+sudo systemctl restart gitea-mirror
+
+# Check status
+sudo systemctl status gitea-mirror
+
+# View logs
+sudo journalctl -u gitea-mirror -f
+
+# Health check
+curl http://localhost:4321/api/health
+```
+
+## Environment Variables
+
+All variables from `docker-compose.alt.yml` are supported:
+
+```bash
+# === AUTO-GENERATED (Don't set unless you want specific values) ===
+BETTER_AUTH_SECRET          # Auto-generated, stored in data dir
+ENCRYPTION_SECRET           # Auto-generated, stored in data dir
+
+# === CORE SETTINGS (Have good defaults) ===
+DATA_DIR="$HOME/.local/share/gitea-mirror"
+DATABASE_URL="file:$DATA_DIR/gitea-mirror.db"
+HOST="0.0.0.0"
+PORT="4321"
+NODE_ENV="production"
+
+# === BETTER AUTH (Override for custom domains) ===
+BETTER_AUTH_URL="http://localhost:4321"
+BETTER_AUTH_TRUSTED_ORIGINS="http://localhost:4321"
+PUBLIC_BETTER_AUTH_URL="http://localhost:4321"
+
+# === CONCURRENCY CONTROLS ===
+MIRROR_ISSUE_CONCURRENCY=3           # Default: 3 (set to 1 for perfect order)
+MIRROR_PULL_REQUEST_CONCURRENCY=5    # Default: 5 (set to 1 for perfect order)
+
+# === CONFIGURE VIA WEB UI (Not needed at startup) ===
+# GitHub credentials, Gitea settings, mirror options, scheduling, etc.
+# All configured after signup through the web interface
+```
+
+## Database Management
+
+The Nix package includes a database management helper:
+
+```bash
+# Initialize database (done automatically on first run)
+gitea-mirror-db init
+
+# Check database health
+gitea-mirror-db check
+
+# Fix database issues
+gitea-mirror-db fix
+
+# Reset users
+gitea-mirror-db reset-users
+```
+
+## Home Manager Integration
+
+For single-user deployments:
+
+```nix
+{ config, pkgs, ... }:
+let
+  gitea-mirror = (import (fetchTarball "https://github.com/RayLabsHQ/gitea-mirror/archive/main.tar.gz")).packages.${pkgs.system}.default;
+in {
+  home.packages = [ gitea-mirror ];
+
+  # Optional: Run as user service
+  systemd.user.services.gitea-mirror = {
+    Unit = {
+      Description = "Gitea Mirror Service";
+      After = [ "network.target" ];
+    };
+
+    Service = {
+      Type = "simple";
+      ExecStart = "${gitea-mirror}/bin/gitea-mirror";
+      Restart = "always";
+      Environment = [
+        "DATA_DIR=%h/.local/share/gitea-mirror"
+        "HOST=127.0.0.1"
+        "PORT=4321"
+      ];
+    };
+
+    Install = {
+      WantedBy = [ "default.target" ];
+    };
+  };
+}
+```
+
+## Docker Image from Nix (Optional)
+
+You can also use Nix to create a Docker image:
+
+```nix
+# Add to flake.nix packages section
+dockerImage = pkgs.dockerTools.buildLayeredImage {
+  name = "gitea-mirror";
+  tag = "latest";
+  contents = [ self.packages.${system}.default pkgs.cacert pkgs.openssl ];
+  config = {
+    Cmd = [ "${self.packages.${system}.default}/bin/gitea-mirror" ];
+    ExposedPorts = { "4321/tcp" = {}; };
+    Env = [
+      "DATA_DIR=/data"
+      "DATABASE_URL=file:/data/gitea-mirror.db"
+    ];
+    Volumes = { "/data" = {}; };
+  };
+};
+```
+
+Build and load:
+```bash
+nix build .#dockerImage
+docker load < result
+docker run -p 4321:4321 -v gitea-mirror-data:/data gitea-mirror:latest
+```
+
+## Comparison: Docker vs Nix
+
+Both deployment methods follow the same philosophy:
+
+| Feature | Docker Compose | Nix |
+|---------|---------------|-----|
+| **Configuration** | Minimal (only BETTER_AUTH_SECRET) | Zero config (auto-generated) |
+| **Secret Generation** | Auto-generated & persisted | Auto-generated & persisted |
+| **Database Init** | Automatic on first run | Automatic on first run |
+| **Startup Scripts** | Runs recovery/repair/env-config | Runs recovery/repair/env-config |
+| **Graceful Shutdown** | Signal handling in entrypoint | Signal handling in wrapper |
+| **Health Check** | Docker healthcheck | systemd timer (optional) |
+| **Updates** | `docker pull` | `nix flake update && nixos-rebuild` |
+
+## Troubleshooting
+
+### Check Auto-Generated Secrets
+```bash
+# For standalone
+cat ~/.local/share/gitea-mirror/.better_auth_secret
+cat ~/.local/share/gitea-mirror/.encryption_secret
+
+# For NixOS service
+sudo cat /var/lib/gitea-mirror/.better_auth_secret
+sudo cat /var/lib/gitea-mirror/.encryption_secret
+```
+
+### Database Issues
+```bash
+# Check if database exists
+ls -la ~/.local/share/gitea-mirror/gitea-mirror.db
+
+# Reinitialize (deletes all data!)
+rm ~/.local/share/gitea-mirror/gitea-mirror.db
+gitea-mirror-db init
+```
+
+### Permission Issues (NixOS)
+```bash
+sudo chown -R gitea-mirror:gitea-mirror /var/lib/gitea-mirror
+sudo chmod 700 /var/lib/gitea-mirror
+```
+
+### Port Already in Use
+```bash
+# Change port
+export PORT=8080
+gitea-mirror
+
+# Or in NixOS config
+services.gitea-mirror.port = 8080;
+```
+
+### View Startup Logs
+```bash
+# Standalone (verbose output on console)
+gitea-mirror
+
+# NixOS service
+sudo journalctl -u gitea-mirror -f --since "5 minutes ago"
+```
+
+## Updating
+
+### Standalone Installation
+```bash
+# Update flake lock
+nix flake update
+
+# Rebuild
+nix build
+
+# Or update profile
+nix profile upgrade gitea-mirror
+```
+
+### NixOS
+```bash
+# Update input
+sudo nix flake lock --update-input gitea-mirror
+
+# Rebuild system
+sudo nixos-rebuild switch
+```
+
+## Migration from Docker
+
+To migrate from Docker to Nix while keeping your data:
+
+1. **Stop Docker container:**
+   ```bash
+   docker-compose -f docker-compose.alt.yml down
+   ```
+
+2. **Copy data directory:**
+   ```bash
+   # For standalone
+   cp -r ./data ~/.local/share/gitea-mirror
+
+   # For NixOS
+   sudo cp -r ./data /var/lib/gitea-mirror
+   sudo chown -R gitea-mirror:gitea-mirror /var/lib/gitea-mirror
+   ```
+
+3. **Copy secrets (if you want to keep them):**
+   ```bash
+   # Extract from Docker volume
+   docker run --rm -v gitea-mirror_data:/data alpine \
+     cat /data/.better_auth_secret > better_auth_secret
+   docker run --rm -v gitea-mirror_data:/data alpine \
+     cat /data/.encryption_secret > encryption_secret
+
+   # Copy to new location
+   cp better_auth_secret ~/.local/share/gitea-mirror/.better_auth_secret
+   cp encryption_secret ~/.local/share/gitea-mirror/.encryption_secret
+   chmod 600 ~/.local/share/gitea-mirror/.*_secret
+   ```
+
+4. **Start Nix version:**
+   ```bash
+   gitea-mirror
+   ```
+
+## CI/CD Integration
+
+Example GitHub Actions workflow:
+
+```yaml
+name: Build with Nix
+
+on: [push, pull_request]
+
+jobs:
+  build:
+    runs-on: ubuntu-latest
+    steps:
+    - uses: actions/checkout@v4
+    - uses: cachix/install-nix-action@v24
+      with:
+        extra_nix_config: |
+          experimental-features = nix-command flakes
+    - uses: cachix/cachix-action@v12
+      with:
+        name: gitea-mirror
+        authToken: '${{ secrets.CACHIX_AUTH_TOKEN }}'
+    - run: nix build
+    - run: nix flake check
+```

+# Nix Distribution - Ready to Use! 🎉
+
+## Current Status: ✅ WORKS NOW
+
+Your Nix package is **already distributable**! Users can run it directly from GitHub without any additional setup on your end.
+
+## How Users Will Use It
+
+### Simple: Just Run From GitHub
+
+```bash
+nix run --extra-experimental-features 'nix-command flakes' github:RayLabsHQ/gitea-mirror
+```
+
+That's it! No releases, no CI, no infrastructure needed. It works right now.
+
+---
+
+## What Happens When They Run This?
+
+1. **Nix fetches** your repo from GitHub
+2. **Nix reads** `flake.nix` and `flake.lock`
+3. **Nix builds** the package on their machine
+4. **Nix runs** the application
+5. **Result cached** in `/nix/store` for reuse
+
+---
+
+## Do You Need CI or Releases?
+
+### For Basic Usage: **NO**
+Users can already use it from GitHub. No CI or releases required.
+
+### For Better UX: **Recommended**
+Set up binary caching so users don't compile from source.
+
+---
+
+## Next Steps (Optional but Recommended)
+
+### Option 1: Add Binary Cache (5 minutes)
+
+**Why:** Users download pre-built binaries instead of compiling (much faster!)
+
+**How:**
+1. Create free account at https://cachix.org/
+2. Create cache named `gitea-mirror`
+3. Add GitHub secret: `CACHIX_AUTH_TOKEN`
+4. GitHub Actions workflow already created at `.github/workflows/nix-build.yml`
+5. Add to your docs:
+   ```bash
+   # Users run once
+   cachix use gitea-mirror
+
+   # Then they get fast binary downloads
+   nix run github:RayLabsHQ/gitea-mirror
+   ```
+
+### Option 2: Release Versioning (2 minutes)
+
+**Why:** Users can pin to specific versions
+
+**How:**
+```bash
+# When ready to release
+git tag v3.8.11
+git push origin v3.8.11
+
+# Users can then pin to this version
+nix run github:RayLabsHQ/gitea-mirror/v3.8.11
+```
+
+No additional CI needed - tags work automatically with flakes!
+
+### Option 3: Submit to nixpkgs (Long Term)
+
+**Why:** Maximum discoverability and trust
+
+**When:** After package is stable and well-tested
+
+**How:** Submit PR to https://github.com/NixOS/nixpkgs
+
+---
+
+## Files Created
+
+### Essential (Already Working)
+- ✅ `flake.nix` - Package definition
+- ✅ `flake.lock` - Dependency lock file
+- ✅ `.envrc` - direnv integration
+
+### Documentation
+- ✅ `NIX.md` - Quick reference for users
+- ✅ `docs/NIX_DEPLOYMENT.md` - Complete deployment guide
+- ✅ `docs/NIX_DISTRIBUTION.md` - Distribution guide for you (maintainer)
+- ✅ `README.md` - Updated with Nix instructions
+
+### CI (Optional, Already Set Up)
+- ✅ `.github/workflows/nix-build.yml` - Builds + caches to Cachix
+
+### Updated
+- ✅ `.gitignore` - Added Nix artifacts
+
+---
+
+## Comparison: Your Distribution Options
+
+| Setup | Time | User Experience | What You Need |
+|-------|------|----------------|---------------|
+| **Direct GitHub** | 0 min ✅ | Slow (build from source) | Nothing! Works now |
+| **+ Cachix** | 5 min | Fast (binary download) | Cachix account + token |
+| **+ Git Tags** | 2 min | Versionable | Just push tags |
+| **+ nixpkgs** | Hours | Official/Trusted | PR review process |
+
+**Recommendation:** Start with Direct GitHub (already works!), add Cachix this week for better UX.
+
+---
+
+## Testing Your Distribution
+
+You can test it right now:
+
+```bash
+# Test direct GitHub usage
+nix run --extra-experimental-features 'nix-command flakes' github:RayLabsHQ/gitea-mirror
+
+# Test with specific commit
+nix run github:RayLabsHQ/gitea-mirror/$(git rev-parse HEAD)
+
+# Validate flake
+nix flake check
+```
+
+---
+
+## User Documentation Locations
+
+Users will find instructions in:
+1. **README.md** - Installation section (already updated)
+2. **NIX.md** - Quick reference
+3. **docs/NIX_DEPLOYMENT.md** - Detailed guide
+
+All docs include the correct commands with experimental features flags.
+
+---
+
+## When to Release New Versions
+
+### For Git Tag Releases:
+```bash
+# 1. Update version in package.json
+vim package.json
+
+# 2. Update version in flake.nix (line 17)
+vim flake.nix  # version = "3.8.12";
+
+# 3. Commit and tag
+git add package.json flake.nix
+git commit -m "chore: bump version to v3.8.12"
+git tag v3.8.12
+git push origin main
+git push origin v3.8.12
+```
+
+Users can then use: `nix run github:RayLabsHQ/gitea-mirror/v3.8.12`
+
+### No Release Needed For:
+- Bug fixes
+- Small changes
+- Continuous updates
+
+Users can always use latest from main: `nix run github:RayLabsHQ/gitea-mirror`
+
+---
+
+## Summary
+
+**✅ Ready to distribute RIGHT NOW**
+- Just commit and push your `flake.nix`
+- Users can run directly from GitHub
+- No CI, releases, or infrastructure required
+
+**🚀 Recommended next: Add Cachix (5 minutes)**
+- Much better user experience
+- Workflow already created
+- Free for public projects
+
+**📦 Optional later: Submit to nixpkgs**
+- Maximum discoverability
+- Official Nix repository
+- Do this once package is stable
+
+See `docs/NIX_DISTRIBUTION.md` for complete details!

+# Nix Package Distribution Guide
+
+This guide explains how Gitea Mirror is distributed via Nix and how users can consume it.
+
+## Distribution Methods
+
+### Method 1: Direct GitHub Usage (Zero Infrastructure)
+
+**No CI, releases, or setup needed!** Users can consume directly from GitHub:
+
+```bash
+# Latest from main branch
+nix run --extra-experimental-features 'nix-command flakes' github:RayLabsHQ/gitea-mirror
+
+# Pin to specific commit
+nix run github:RayLabsHQ/gitea-mirror/abc123def
+
+# Pin to git tag
+nix run github:RayLabsHQ/gitea-mirror/v3.8.11
+```
+
+**How it works:**
+1. Nix fetches the repository from GitHub
+2. Nix reads `flake.nix` and `flake.lock`
+3. Nix builds the package locally on the user's machine
+4. Package is cached in `/nix/store` for reuse
+
+**Pros:**
+- Zero infrastructure needed
+- Works immediately after pushing code
+- Users always get reproducible builds
+
+**Cons:**
+- Users must build from source (slower first time)
+- Requires build dependencies (Bun, etc.)
+
+---
+
+### Method 2: Binary Cache (Recommended)
+
+Pre-build packages and cache them so users download binaries instead of building:
+
+#### Setup: Cachix (Free for Public Projects)
+
+1. **Create account:** https://cachix.org/
+2. **Create cache:** `gitea-mirror` (public)
+3. **Add secret to GitHub:** `Settings → Secrets → CACHIX_AUTH_TOKEN`
+4. **GitHub Actions builds automatically** (see `.github/workflows/nix-build.yml`)
+
+#### User Experience:
+
+```bash
+# First time: Configure cache
+cachix use gitea-mirror
+
+# Or add to nix.conf:
+# substituters = https://cache.nixos.org https://gitea-mirror.cachix.org
+# trusted-public-keys = cache.nixos.org-1:6NCHdD59X431o0gWypbMrAURkbJ16ZPMQFGspcDShjY= gitea-mirror.cachix.org-1:YOUR_KEY_HERE
+
+# Then use normally - downloads pre-built binaries!
+nix run github:RayLabsHQ/gitea-mirror
+```
+
+**Pros:**
+- Fast installation (no compilation)
+- Reduced bandwidth/CPU for users
+- Professional experience
+
+**Cons:**
+- Requires Cachix account (free for public)
+- Requires CI setup
+
+---
+
+### Method 3: nixpkgs Submission (Official Distribution)
+
+Submit to the official Nix package repository for maximum visibility.
+
+#### Process:
+
+1. **Prepare package** (already done with `flake.nix`)
+2. **Test thoroughly**
+3. **Submit PR to nixpkgs:** https://github.com/NixOS/nixpkgs
+
+#### User Experience:
+
+```bash
+# After acceptance into nixpkgs
+nix run nixpkgs#gitea-mirror
+
+# NixOS configuration
+environment.systemPackages = [ pkgs.gitea-mirror ];
+```
+
+**Pros:**
+- Maximum discoverability (official repo)
+- Trusted by Nix community
+- Included in NixOS search
+- Binary caching by cache.nixos.org
+
+**Cons:**
+- Submission/review process
+- Must follow nixpkgs guidelines
+- Updates require PRs
+
+---
+
+## Current Distribution Strategy
+
+### Phase 1: Direct GitHub (Immediate) ✅
+
+Already working! Users can:
+
+```bash
+nix run github:RayLabsHQ/gitea-mirror
+```
+
+### Phase 2: Binary Cache (Recommended Next)
+
+Set up Cachix for faster installs:
+
+1. Create Cachix cache
+2. Add `CACHIX_AUTH_TOKEN` secret to GitHub
+3. Workflow already created in `.github/workflows/nix-build.yml`
+4. Add instructions to docs
+
+### Phase 3: Version Releases (Optional)
+
+Tag releases for version pinning:
+
+```bash
+git tag v3.8.11
+git push origin v3.8.11
+
+# Users can then pin:
+nix run github:RayLabsHQ/gitea-mirror/v3.8.11
+```
+
+### Phase 4: nixpkgs Submission (Long Term)
+
+Once package is stable and well-tested, submit to nixpkgs.
+
+---
+
+## User Documentation
+
+### For Users: How to Install
+
+Add this to your `docs/NIX_DEPLOYMENT.md`:
+
+#### Option 1: Direct Install (No Configuration)
+
+```bash
+# Run immediately
+nix run --extra-experimental-features 'nix-command flakes' github:RayLabsHQ/gitea-mirror
+
+# Install to profile
+nix profile install --extra-experimental-features 'nix-command flakes' github:RayLabsHQ/gitea-mirror
+```
+
+#### Option 2: With Binary Cache (Faster)
+
+```bash
+# One-time setup
+cachix use gitea-mirror
+
+# Then install (downloads pre-built binary)
+nix profile install github:RayLabsHQ/gitea-mirror
+```
+
+#### Option 3: Pin to Specific Version
+
+```bash
+# Pin to git tag
+nix run github:RayLabsHQ/gitea-mirror/v3.8.11
+
+# Pin to commit
+nix run github:RayLabsHQ/gitea-mirror/abc123def
+
+# Lock in flake.nix
+inputs.gitea-mirror.url = "github:RayLabsHQ/gitea-mirror/v3.8.11";
+```
+
+#### Option 4: NixOS Configuration
+
+```nix
+{
+  inputs = {
+    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
+    gitea-mirror.url = "github:RayLabsHQ/gitea-mirror";
+    # Or pin to version:
+    # gitea-mirror.url = "github:RayLabsHQ/gitea-mirror/v3.8.11";
+  };
+
+  outputs = { nixpkgs, gitea-mirror, ... }: {
+    nixosConfigurations.your-host = nixpkgs.lib.nixosSystem {
+      modules = [
+        gitea-mirror.nixosModules.default
+        {
+          services.gitea-mirror = {
+            enable = true;
+            betterAuthUrl = "https://mirror.example.com";
+            openFirewall = true;
+          };
+        }
+      ];
+    };
+  };
+}
+```
+
+---
+
+## Maintaining the Distribution
+
+### Releasing New Versions
+
+```bash
+# 1. Update version in package.json
+vim package.json  # Update version field
+
+# 2. Update flake.nix version (line 17)
+vim flake.nix  # Update version = "X.Y.Z";
+
+# 3. Commit changes
+git add package.json flake.nix
+git commit -m "chore: bump version to vX.Y.Z"
+
+# 4. Create git tag
+git tag vX.Y.Z
+git push origin main
+git push origin vX.Y.Z
+
+# 5. GitHub Actions builds and caches automatically
+```
+
+Users can then pin to the new version:
+```bash
+nix run github:RayLabsHQ/gitea-mirror/vX.Y.Z
+```
+
+### Updating Flake Lock
+
+The `flake.lock` file pins all dependencies. Update it periodically:
+
+```bash
+# Update all inputs
+nix flake update
+
+# Update specific input
+nix flake lock --update-input nixpkgs
+
+# Test after update
+nix build
+nix flake check
+
+# Commit the updated lock file
+git add flake.lock
+git commit -m "chore: update flake dependencies"
+git push
+```
+
+---
+
+## Troubleshooting Distribution Issues
+
+### Users Report Build Failures
+
+1. **Check GitHub Actions:** Ensure CI is passing
+2. **Test locally:** `nix flake check`
+3. **Check flake.lock:** May need update if dependencies changed
+
+### Cachix Not Working
+
+1. **Verify cache exists:** https://gitea-mirror.cachix.org
+2. **Check GitHub secret:** `CACHIX_AUTH_TOKEN` is set
+3. **Review workflow logs:** Ensure build + push succeeded
+
+### Version Pinning Not Working
+
+```bash
+# Verify tag exists
+git tag -l
+
+# Ensure tag is pushed
+git ls-remote --tags origin
+
+# Test specific tag
+nix run github:RayLabsHQ/gitea-mirror/v3.8.11
+```
+
+---
+
+## Advanced: Custom Binary Cache
+
+If you prefer self-hosting instead of Cachix:
+
+### Option 1: S3-Compatible Storage
+
+```nix
+# Generate signing key
+nix-store --generate-binary-cache-key cache.example.com cache-priv-key.pem cache-pub-key.pem
+
+# Push to S3
+nix copy --to s3://my-nix-cache?region=us-east-1 $(nix-build)
+```
+
+Users configure:
+```nix
+substituters = https://my-bucket.s3.amazonaws.com/nix-cache
+trusted-public-keys = cache.example.com:BASE64_PUBLIC_KEY
+```
+
+### Option 2: Self-Hosted Nix Store
+
+Run `nix-serve` on your server:
+
+```bash
+# On server
+nix-serve -p 8080
+
+# Behind nginx/caddy
+proxy_pass http://localhost:8080;
+```
+
+Users configure:
+```nix
+substituters = https://cache.example.com
+trusted-public-keys = YOUR_KEY
+```

+## Comparison: Distribution Methods
+
+| Method | Setup Time | User Speed | Cost | Discoverability |
+|--------|-----------|------------|------|-----------------|
+| Direct GitHub | 0 min | Slow (build) | Free | Low |
+| Cachix | 5 min | Fast (binary) | Free (public) | Medium |
+| nixpkgs | Hours/days | Fast (binary) | Free | High |
+| Self-hosted | 30+ min | Fast (binary) | Server cost | Low |
+
+**Recommendation:** Start with **Direct GitHub** (works now), add **Cachix** for better UX (5 min), consider **nixpkgs** later for maximum reach.

-### Method 2: Binary Cache (Recommended)
+### Method 2: CI Build Caching
 
-Pre-build packages and cache them so users download binaries instead of building:
+The GitHub Actions workflow uses **Magic Nix Cache** (by Determinate Systems) to cache builds:
 
-#### Setup: Cachix (Free for Public Projects)
+- **Zero configuration required** - no accounts or tokens needed
+- **Automatic** - CI workflow handles everything
+- **Uses GitHub Actions cache** - fast, reliable, free
 
-1. **Create account:** https://cachix.org/
-2. **Create cache:** `gitea-mirror` (public)
-3. **Add secret to GitHub:** `Settings → Secrets → CACHIX_AUTH_TOKEN`
-4. **GitHub Actions builds automatically** (see `.github/workflows/nix-build.yml`)
+#### How It Works:
 
-#### User Experience:
+1. GitHub Actions builds the package on each push/PR
+2. Build artifacts are cached in GitHub Actions cache
+3. Subsequent builds reuse cached dependencies (faster CI)
 
-```bash
-# First time: Configure cache
-cachix use gitea-mirror
-
-# Or add to nix.conf:
-# substituters = https://cache.nixos.org https://gitea-mirror.cachix.org
-# trusted-public-keys = cache.nixos.org-1:6NCHdD59X431o0gWypbMrAURkbJ16ZPMQFGspcDShjY= gitea-mirror.cachix.org-1:YOUR_KEY_HERE
-
-# Then use normally - downloads pre-built binaries!
-nix run github:RayLabsHQ/gitea-mirror
-```
-
-**Pros:**
-- Fast installation (no compilation)
-- Reduced bandwidth/CPU for users
-- Professional experience
-
-**Cons:**
-- Requires Cachix account (free for public)
-- Requires CI setup
+Note: This caches CI builds. Users still build locally, but the flake.lock ensures reproducibility.
