+# CI/CD Setup — Forgejo Actions Registry Credentials
+
+## Required Configuration
+
+The CI pipeline (`.forgejo/workflows/build.yaml`) automatically builds and pushes Docker images on each push to `main`. However, it requires registry credentials to be configured as repository secrets.
+
+### Setup Steps
+
+#### 1. **Get Registry Credentials**
+
+From the homelab setup:
+```bash
+# Get ci-bot token (or use your personal access token)
+kubectl get secret -n poimen $(kubectl get secret -n poimen -l app.kubernetes.io/name=ci-bot -o name | head -1) -o jsonpath='{.data.token}' | base64 -d
+```
+
+Or use a personal Forgejo access token:
+- URL: https://forgejo.riotpiao.com/user/settings/tokens
+- Create token with `write:package` scope
+
+#### 2. **Set Repository Secrets**
+
+Go to: **https://git.riotpiao.com/rock/poimen-memory/settings/secrets**
+
+Add two secrets:
+- **`REGISTRY_USER`**: `ci-bot` (or your username)
+- **`REGISTRY_TOKEN`**: `<token-from-step-1>`
+
+#### 3. **Verify Setup**
+
+Push a commit and check:
+```bash
+# Via web UI
+https://git.riotpiao.com/rock/poimen-memory/actions
+
+# Or check if image exists
+docker pull forgejo.riotpiao.com/rock/poimen-memory:latest
+```
+
+---
+
+## How It Works
+
+```
+┌─────────────────┐
+│  Push to main   │
+└────────┬────────┘
+         │
+         ↓
+┌─────────────────────────────────────────┐
+│  Forgejo Actions (rust runner)          │
+│  1. cargo build --workspace             │
+│  2. cargo test --all                    │
+└────────┬────────────────────────────────┘
+         │
+         ↓ (only if tests pass)
+┌─────────────────────────────────────────┐
+│  Build Docker Image                     │
+│  docker build -t forgejo.../latest .    │
+└────────┬────────────────────────────────┘
+         │
+         ↓
+┌─────────────────────────────────────────┐
+│  Push to Registry                       │
+│  docker login + push                    │
+│  Uses: REGISTRY_USER + REGISTRY_TOKEN   │
+└────────┬────────────────────────────────┘
+         │
+         ↓
+┌─────────────────────────────────────────┐
+│  ArgoCD Detects Image                   │
+│  Syncs k8s/app/ with new image          │
+└────────┬────────────────────────────────┘
+         │
+         ↓
+┌─────────────────────────────────────────┐
+│  K8s Deployment                         │
+│  Pulls new image, restarts pods         │
+└─────────────────────────────────────────┘
+```
+

+
+## Troubleshooting
+
+### Build Fails During Tests
+- Check workflow logs: https://git.riotpiao.com/rock/poimen-memory/actions
+- Run locally: `cargo test --all`
+
+### Image Not Pushing
+- Verify `REGISTRY_TOKEN` secret is set correctly
+- Check docker login error in workflow logs
+- Ensure token has `write:package` scope
+
+### ArgoCD Not Syncing
+```bash
+kubectl get application -n argocd poimen-memory-app -o yaml | grep -A 5 status
+```
+
+---
+
+## Manual Alternative
+
+If CI is not working, you can push manually:
+
+```bash
+# From homelab machine (has registry access)
+cd ~/workplace/Poimen/memory
+cargo build --release
+docker build -t forgejo.riotpiao.com/rock/poimen-memory:latest .
+docker push forgejo.riotpiao.com/rock/poimen-memory:latest
+```
+
+But the goal is **zero-touch CI/CD**, so set up the secrets once and forget about it.
+
+---
+
+## Status
+
+- ✅ Workflow file: `.forgejo/workflows/build.yaml`
+- ✅ ArgoCD App: `k8s/argocd/memory-app.yaml`
+- ⏳ **Required**: Set `REGISTRY_USER` and `REGISTRY_TOKEN` secrets
+- ⏳ Then: Push to main, watch image build and deploy automatically
