 Key architecture documents: see [architecture](docs/architecture/README.md) for the arc42-based architecture documentation.
 
 For contributors: the `routes/`, `models/` and `services/` folders contain the primary application code. Tests and E2E specs are in `tests/`.
+
+## Run with Docker
+
+The repository ships with a multi-stage `Dockerfile` that produces a slim runtime image.
+
+```powershell
+# Build the image locally
+docker build -t calminer:latest .
+
+# Run the container (exposes FastAPI on http://localhost:8000)
+docker run --rm -p 8000:8000 calminer:latest
+
+# Provide environment variables (e.g., database URL)
+docker run --rm -p 8000:8000 -e DATABASE_URL="postgresql://user:pass@host/db" calminer:latest
+```
+
+Use `docker compose` or an orchestrator of your choice to co-locate PostgreSQL/Redis alongside the app when needed. The image expects migrations to be applied before startup.
+
+## CI/CD expectations
+
+CalMiner uses Gitea Actions workflows stored in `.gitea/workflows/`:
+
+- `test.yml` runs style/unit/e2e suites on every push with cached Python dependencies.
+- `build-and-push.yml` builds the Docker image, reuses cached layers, and pushes to the configured registry.
+- `deploy.yml` pulls the pushed image on the target host and restarts the container.
+
+Pipelines assume the following secrets are provisioned in the Gitea instance: `GITEA_USERNAME`, `GITEA_PASSWORD`, `GITEA_REGISTRY`, `SSH_HOST`, `SSH_USERNAME`, and `SSH_PRIVATE_KEY`.

 ## Deployment Topology
@@ -23,8 +25,8 @@ The infrastructure components for the application include:
 - **Database Server**: PostgreSQL database for persisting application data.
 - **Static File Server**: Serves static assets such as CSS, JavaScript, and image files.
 - **Reverse Proxy (optional)**: An Nginx or Apache server can be used as a reverse proxy.
-- **CI/CD Pipeline (optional)**: Automated deployment pipelines can be set up using tools like GitHub Actions.
-- **Containerization (optional)**: Docker can be used to containerize the application.
+- **Containerization**: Docker images are generated via the repository `Dockerfile`, using a multi-stage build to keep the final runtime minimal.
+- **CI/CD Pipeline**: Automated pipelines (Gitea Actions) run tests, build/push Docker images, and trigger deployments.
 - **Cloud Infrastructure (optional)**: The application can be deployed on cloud platforms.
 
 ## Environments

+## Containerized Deployment Flow
+
+The Docker-based deployment path aligns with the solution strategy documented in [04 — Solution Strategy](04_solution_strategy.md) and the CI practices captured in [14 — Testing & CI](14_testing_ci.md).
+
+### Image Build
+
+- The multi-stage `Dockerfile` installs dependencies in a builder layer (including system compilers and Python packages) and copies only the required runtime artifacts to the final image.
+- Build arguments are minimal; environment configuration (e.g., `DATABASE_URL`) is supplied at runtime. Secrets and configuration should be passed via environment variables or an orchestrator.
+- The resulting image exposes port `8000` and starts `uvicorn main:app` (s. [README.md](../README.md)).
+
+### Runtime Environment
+
+- For single-node deployments, run the container alongside PostgreSQL/Redis using Docker Compose or an equivalent orchestrator.
+- A reverse proxy (e.g., Nginx) terminates TLS and forwards traffic to the container on port `8000`.
+- Migrations must be applied prior to rolling out a new image; automation can hook into the deploy step to run `scripts/run_migrations.py`.
+
+### CI/CD Integration
+
+- Gitea Actions workflows reside under `.gitea/workflows/`.
+- `test.yml` executes the pytest suite using cached pip dependencies.
+- `build-and-push.yml` logs into the container registry, rebuilds the Docker image using GitHub Actions cache-backed layers, and pushes `latest` (and additional tags as required).
+- `deploy.yml` connects to the target host via SSH, pulls the pushed tag, stops any existing container, and launches the new version.
+- Required secrets: `GITEA_REGISTRY`, `GITEA_USERNAME`, `GITEA_PASSWORD`, `SSH_HOST`, `SSH_USERNAME`, `SSH_PRIVATE_KEY`.
+- Extend these workflows when introducing staging/blue-green deployments; keep cross-links with [14 — Testing & CI](14_testing_ci.md) up to date.
+
 ## Integrations and Future Work (deployment-related)
 
 - **Persistence of results**: `/api/simulations/run` currently returns in-memory results; next iteration should persist to `simulation_result` and reference scenarios.
-- **Deployment**: documentation focuses on local development; containerization and CI/CD pipelines remain to be defined. Consider Docker + GitHub Actions or a simple Docker Compose for local stacks.
+- **Deployment**: implement infrastructure-as-code (e.g., Terraform/Ansible) to provision the hosting environment and maintain parity across dev/stage/prod.

+`build-and-push.yml` adds:
+
+- Registry login using repository secrets.
+- Docker image build/push with GHA cache storage (`cache-from/cache-to` set to `type=gha`).

+- SSH into the deployment host.
+- Pull the tagged image from the registry.
+- Stop, remove, and relaunch the `calminer` container exposing port 8000.
+
+When adding new workflows, mirror this structure to ensure secrets, caching, and deployment steps remain aligned with the production environment.

+## Docker-based setup
+
+To build and run the application using Docker instead of a local Python environment:
+
+```powershell
+# Build the application image (multi-stage build keeps runtime small)
+docker build -t calminer:latest .
+
+# Start the container on port 8000
+docker run --rm -p 8000:8000 calminer:latest
+
+# Supply environment variables (e.g., Postgres connection)
+docker run --rm -p 8000:8000 -e DATABASE_URL="postgresql://user:pass@host/db" calminer:latest
+```
+
+If you maintain a Postgres or Redis dependency locally, consider authoring a `docker compose` stack that pairs them with the app container. The Docker image expects the database to be reachable and migrations executed before serving traffic.
