+# WetGIT — Nederlandse wetgeving als code
+
+## Project
+
+Elke Nederlandse wet als Markdown-bestand, elke wijziging als Git-commit. Data van officiële BWB (Basis Wettenbestand) XML bronnen.
+
+## Stack
+
+- **Python 3.12+** (pyproject.toml, setuptools)
+- **FastAPI** — API + web frontend (module: `wetgit.api.app:app`)
+- **Meilisearch v1.12** — full-text search
+- **Qdrant v1.13** — semantic search (Mistral embeddings)
+- **Forgejo** — self-hosted git (git.wetgit.nl)
+- **Redis** — Celery broker
+- **Nginx** — reverse proxy (3 vhosts: wetgit.nl, api.wetgit.nl, git.wetgit.nl)
+- **Codeberg** — public mirror (codeberg.org/wetgit, daily push)
+
+## API Endpoints

+Rate limiting: 60 req/min default, 30 req/min voor zoeken (slowapi).
+
+## Deployment
+
+```bash
+# Full deploy
+ansible-playbook ansible/site.yml
+
+# Selective
+ansible-playbook ansible/site.yml --tags app      # code + deps + services
+ansible-playbook ansible/site.yml --tags docker    # Docker stack
+ansible-playbook ansible/site.yml --tags nginx     # nginx vhosts + SSL
+ansible-playbook ansible/site.yml --tags forgejo   # Forgejo + Redis + cron
+
+# Dry-run
+ansible-playbook ansible/site.yml --check --diff
+```
+
+Server: dt-prod-01 via Tailscale (100.98.29.89), user: deploy.
+Vault password: `ansible/.vault_pass`
+
+**Important:** Data lives at `/opt/wetgit/app/rijk/` (env var `WETGIT_GIT_REPOS_DIR=/opt/wetgit/app`).
+
+## Shared server rules
+
+This server is shared with **dt-platform**. Do NOT:
+- Modify global nginx.conf or system packages
+- Use ports 8001 (dt-chatbot) or 8200 (grimoire)
+- Touch /opt/dt-chatbot, /opt/grimoire, /opt/dt-skills-portal
+
+## Development
+
+```bash
+# Enter nix shell (provides Python + dependencies)
+nix develop
+
+# Run tests
+pytest
+
+# Run locally
+uvicorn wetgit.api.app:app --reload
+
+# Lint
+ruff check src/
+black --check src/
+```
+
+## Key directories
+
+```
+src/wetgit/          # Application code
+  api/               # FastAPI routes, search, models
+  web/               # Jinja2 templates + static
+  pipeline/          # BWB parser, SRU client, sync, indexer
+  ai/                # Summaries, semantic search, alerts, domains, crossref
+  cli/               # CLI tool
+  tasks.py           # Celery app (sync, reindex, alerts)
+ansible/             # Deployment playbooks
+  roles/             # wetgit-forgejo, wetgit-app, wetgit-nginx
+  group_vars/wetgit/ # main.yml (vars), vault.yml (secrets)
+PRD/                 # Product Requirements Document
+```
+
+## Troubleshooting
+
+- **Port 8002 bezet na deploy:** `ssh deploy@100.98.29.89 "sudo fuser -k 8002/tcp && sudo systemctl restart wetgit"`
+- **Meilisearch crasht:** Check image version — v1.12 data is incompatibel met v1.13
+- **Ansible check-mode faalt op wetgit-web.conf:** Verwacht — file wordt niet echt geschreven in check-mode
