+# Docker Hub Integration Setup
+
+## Required Secrets
+
+Add these secrets to your Gitea repository settings:
+
+### 1. DOCKER_HUB_USERNAME
+- Your Docker Hub username (e.g., "jskala")
+
+### 2. DOCKER_HUB_TOKEN
+- Your Docker Hub access token (NOT your password)
+
+## Creating a Docker Hub Access Token
+
+1. Go to [Docker Hub](https://hub.docker.com/)
+2. Sign in to your account
+3. Click your avatar → **Account Settings**
+4. Go to **Security** tab
+5. Click **New Access Token**
+6. Name it: `NFOGuard-CI`
+7. Permissions: **Read, Write, Delete**
+8. Click **Generate**
+9. **Copy the token immediately** (you won't see it again)
+
+## Adding Secrets to Gitea
+
+1. Go to your NFOguard repository in Gitea
+2. Click **Settings** → **Secrets**
+3. Add the following secrets:
+   - **Name**: `DOCKER_HUB_USERNAME`
+   - **Value**: Your Docker Hub username
+   
+   - **Name**: `DOCKER_HUB_TOKEN`  
+   - **Value**: The access token you generated
+
+## What Gets Published
+
+### Main Branch (Production)
+- `yourusername/nfoguard:latest`
+- `yourusername/nfoguard:v1.5.2` (version from VERSION file)
+- `yourusername/nfoguard:sha-abc123` (git commit SHA)
+
+### Dev Branch
+- `yourusername/nfoguard:dev`
+- `yourusername/nfoguard:dev-sha-abc123`
+
+## Usage Examples
+
+Once set up, users can pull from either registry:
+
+```bash
+# From your local Gitea registry (fast for you)
+docker pull 192.168.253.221:3000/jskala/nfoguard:latest
+
+# From Docker Hub (public access)
+docker pull yourusername/nfoguard:latest
+
+# Dev versions
+docker pull yourusername/nfoguard:dev
+```
+
+## Testing the Setup
+
+After adding the secrets, push a commit to trigger the CI:
+
+```bash
+git add .
+git commit -m "Add Docker Hub CI integration"
+git push origin main
+```
+
+Watch the Actions tab in Gitea to see both registries being pushed to successfully!
+
+## Benefits
+
+- **Local**: Ultra-fast local builds and deployment
+- **Public**: Anyone can use `docker pull yourusername/nfoguard:latest`
+- **Redundancy**: Multiple image sources
+- **Versioning**: Proper semantic versioning across both registries
