+# Movies Diary
+
+A self-hosted, server-side rendered movie logging system with a full REST API. Built in Rust — no JavaScript in the HTML interface, just HTML forms and an RSS feed. Designed to run as a lightweight widget embedded on a personal site or as a backend for third-party clients.
+
+## Features
+
+- Log movies with a TMDB/OMDb ID or manual title/year/director, with a 0–5 rating
+- Immutable append-only viewing ledger (tracks re-watches)
+- Background poster fetching and storage (local filesystem or S3-compatible)
+- RSS/Atom feed for public subscription (global and per-user)
+- JWT authentication via cookie (HTML) or Bearer token (REST API)
+- ActivityPub federation — follow/unfollow remote users on any compatible server, accept/reject/remove followers, pending follow request management
+- CSV and JSON diary export (full round-trip: exported files can be re-imported via the TUI bulk import)
+- REST API v1 (`/api/v1/`) with full feature parity with the HTML interface
+- OpenAPI documentation at `/docs` (Swagger UI) and `/scalar` (Scalar)
+- CSRF protection on all HTML form routes (double-submit cookie, defense-in-depth on top of `SameSite=Strict`)
+- Per-IP rate limiting via token bucket (production-grade, backed by `axum-governor`)
+- Terminal UI client (`crates/tui`) for logging reviews, bulk CSV import, and diary browsing
+
+## Architecture
+
+Hexagonal (Ports & Adapters) with Domain-Driven Design:
+
+```
+domain              — pure types and trait definitions, no external deps
+application         — use cases / business logic orchestration
+presentation        — Axum HTTP router, wires all adapters together
+adapters/
+  auth              — JWT issuance and validation (Argon2 passwords)
+  sqlite            — SQLite repository via sqlx
+  metadata          — OMDb HTTP client
+  poster-fetcher    — downloads poster images
+  poster-storage    — uploads posters to local filesystem or S3-compatible storage
+  template-askama   — Askama HTML rendering
+  rss               — RSS/Atom feed generation
+  export            — CSV and JSON diary serialization
+  event-publisher   — async event channel for background poster sync
+  activitypub       — ActivityPub federation (follow, inbox/outbox, actor)
+  activitypub-base  — core ActivityPub types and repository traits
+doc                 — OpenAPI spec assembly and Swagger UI / Scalar serving
+tui                 — terminal UI client (ratatui)
+```
+
+## Prerequisites
+
+- Rust (stable, 2024 edition)
+- SQLite
+- Poster storage: local filesystem (zero deps) or an S3-compatible object store (e.g. MinIO)
+- An [OMDb API key](https://www.omdbapi.com/apikey.aspx)
+
+## Environment Variables
+
+A `.env.example` file is provided at the repo root — copy it to `.env` and fill in your values.
+
+```env
+# Database
+DATABASE_URL=sqlite://movies.db
+
+# Authentication
+JWT_SECRET=change-me
+
+# OMDb metadata
+OMDB_API_KEY=your-key
+
+# Public base URL (used for ActivityPub actor URLs and canonical links)
+BASE_URL=https://yourdomain.example.com
+
+# Poster storage — pick one backend:
+
+# Option A: local filesystem (zero deps)
+POSTER_STORAGE_BACKEND=local
+POSTER_STORAGE_PATH=./posters
+
+# Option B: S3-compatible (MinIO, AWS S3, etc.)
+# POSTER_STORAGE_BACKEND=s3
+# MINIO_ENDPOINT=http://localhost:9000
+# MINIO_BUCKET=posters
+# MINIO_REGION=minio
+# MINIO_ACCESS_KEY_ID=minioadmin
+# MINIO_SECRET_ACCESS_KEY=minioadmin
+
+# Optional
+HOST=0.0.0.0
+PORT=3000
+RATE_LIMIT=60           # requests per minute per IP (default: 60)
+ALLOW_REGISTRATION=true # set to false to disable new sign-ups
+SECURE_COOKIES=true     # set when serving over HTTPS
+RUST_LOG=presentation=info,tower_http=info
+```
+
+## Run
+
+```bash
+cargo run -p presentation
+```
+
+Server listens on `0.0.0.0:3000` by default.
+
+## API
+
+All REST endpoints are under `/api/v1/`. Authentication uses `Authorization: Bearer <token>` obtained from `POST /api/v1/auth/login`.
+
+Interactive API documentation is available at runtime:
+
+- **Swagger UI** — `http://localhost:3000/docs`
+- **Scalar** — `http://localhost:3000/scalar`
