+# Project: ComFi Management System
+
+## Overview
+ComFi is a React-based financial and management dashboard.
+- **Frontend:** React 19, Vite, TypeScript.
+- **Serving (Production):** Node.js (Express) via `server.js`.
+- **State Management:** Context API (`ComFiContext`, `ToastContext`).
+- **Styling:** CSS / Lucide React icons.
+
+## Architecture
+
+### Current (Local)
+- **Dev Server:** `vite` (HMR, local dev).
+- **Prod Preview:** `node server.js` serving `dist/`.
+
+### Target (Production)
+- **Containerization:** Docker (Multi-stage build).
+- **Orchestration:** Docker Swarm (managed via Portainer).
+- **CI/CD:** Gitea Actions.
+- **Reverse Proxy:** Traefik or Nginx (implied by Swarm/Portainer setup, usually handles SSL termination).
+
+## Deployment Roadmap
+
+### 1. Dockerization
+- Create `Dockerfile`:
+  - **Stage 1 (Builder):** Install deps, run `npm run build` to generate `dist/`.
+  - **Stage 2 (Runner):** Alpine Node image, copy `dist/`, `server.js`, and `package.json`. Run `npm install --production`.
+- Create `docker-compose.yml` for local testing of the production build.
+
+### 2. CI/CD (Gitea Actions)
+- Define workflow `.gitea/workflows/deploy.yaml`.
+- **Steps:**
+  - Checkout code.
+  - Login to Container Registry.
+  - Build and Push Docker Image (tagged with commit SHA and `latest`).
+  - Trigger Deployment (Portainer Webhook).
+
+### 3. Portainer & Swarm Configuration
+- **Stack Definition:** A `docker-compose` style file for Swarm.
+- **Secrets Management:**
+  - Registry Credentials (if private).
+  - Environment variables (if any, e.g., API endpoints).
+- **Update Mechanism:** Webhook URL provided by Portainer Service.
+
+## Required Configuration & Secrets
+To proceed, we will need to define:
+1.  **Registry URL:** `gitea.blyzer.com.br`
+2.  **Image Name:** `gitea.blyzer.com.br/blyzer/comfi`
+3.  **Portainer Webhook:** The URL Portainer provides to trigger a service update.
+
+### Secrets (Gitea)
+Set these in your Gitea repository settings (Settings > Actions > Secrets):
+- `REGISTRY_USERNAME`: Your Gitea username.
+- `REGISTRY_TOKEN`: Your Gitea password or token.
+- `PORTAINER_WEBHOOK`: The full webhook URL from Portainer.
+- `API_KEY`: (Optional) Google GenAI API key.
+
+## Directives
+- **Conventions:** Follow existing TypeScript and React patterns.
+- **Safety:** Do not commit `.env` files.
+- **Style:** Maintain the clean, dashboard-style UI.
