+# Docker Hub Quick Start Guide
+
+## 🚀 Quick Setup (3 Steps)
+
+### 1. Create Docker Hub Secrets
+
+```bash
+./infrastructure/kubernetes/setup-dockerhub-secrets.sh
+```
+
+This creates the `dockerhub-creds` secret in all namespaces with your Docker Hub credentials.
+
+### 2. Apply Updated Manifests
+
+```bash
+# Development environment
+kubectl apply -k infrastructure/kubernetes/overlays/dev
+
+# Production environment
+kubectl apply -k infrastructure/kubernetes/overlays/prod
+```
+
+### 3. Verify Pods Are Running
+
+```bash
+kubectl get pods -n bakery-ia
+```
+
+All pods should now be able to pull images from Docker Hub!
+
+---
+
+## 🔧 What Was Configured
+
+✅ **Docker Hub Credentials**
+- Username: `uals`
+- Access Token: `dckr_pat_zzEY5Q58x1S0puraIoKEtbpue3A`
+- Email: `ualfaro@gmail.com`
+
+✅ **Kubernetes Secrets**
+- Created in: `bakery-ia`, `bakery-ia-dev`, `bakery-ia-prod`, `default`
+- Secret name: `dockerhub-creds`
+
+✅ **Manifests Updated (47 files)**
+- All service deployments
+- All database deployments
+- All migration jobs
+- All cronjobs and standalone jobs
+
+✅ **Tiltfile Configuration**
+- Supports both local registry and Docker Hub
+- Use `export USE_DOCKERHUB=true` to enable Docker Hub mode
+
+---
+
+## 📖 Full Documentation
+
+See [docs/DOCKERHUB_SETUP.md](docs/DOCKERHUB_SETUP.md) for:
+- Detailed configuration steps
+- Troubleshooting guide
+- Security best practices
+- Image management
+- Rate limits information
+
+---
+
+## 🔄 Using with Tilt (Local Development)
+
+**Default: Local Registry**
+```bash
+tilt up
+```
+
+**Docker Hub Mode**
+```bash
+export USE_DOCKERHUB=true
+export DOCKERHUB_USERNAME=uals
+docker login -u uals
+tilt up
+```
+
+---
+
+## 🐳 Pushing Images to Docker Hub
+
+```bash
+# Login first
+docker login -u uals
+
+# Use the automated script
+./scripts/tag-and-push-images.sh
+```
+
+---
+
+## ⚠️ Troubleshooting
+
+**Problem: ImagePullBackOff**
+```bash
+# Check if secret exists
+kubectl get secret dockerhub-creds -n bakery-ia
+
+# Recreate secret if needed
+./infrastructure/kubernetes/setup-dockerhub-secrets.sh
+```
+
+**Problem: Pods not using new credentials**
+```bash
+# Restart deployment
+kubectl rollout restart deployment/<deployment-name> -n bakery-ia
+```
+
+---
+
+## 📝 Scripts Reference
+
+| Script | Purpose |
+|--------|---------|
+| `infrastructure/kubernetes/setup-dockerhub-secrets.sh` | Create Docker Hub secrets in all namespaces |
+| `infrastructure/kubernetes/add-image-pull-secrets.sh` | Add imagePullSecrets to manifests (already done) |
+| `scripts/tag-and-push-images.sh` | Tag and push all custom images to Docker Hub |
+
+---
+
+## ✅ Verification Checklist
+
+- [ ] Docker Hub secret created: `kubectl get secret dockerhub-creds -n bakery-ia`
+- [ ] Manifests applied: `kubectl apply -k infrastructure/kubernetes/overlays/dev`
+- [ ] Pods running: `kubectl get pods -n bakery-ia`
+- [ ] No ImagePullBackOff errors: `kubectl get events -n bakery-ia`
