+# Authelia
+
+## Overview
+
+Single sign-on and 2FA portal for protecting apps behind a reverse proxy (lighter replacement for Authentik).
+
+## Project Details
+
+-   **Project Repository:** [GitHub](https://github.com/authelia/authelia)
+-   **Container Image:** [authelia/authelia](https://hub.docker.com/r/authelia/authelia)
+-   **Documentation:** [authelia.com](https://www.authelia.com/)
+-   **Reverse Proxy Port:** `9091`
+
+## Getting Started
+
+1. Start the container: `docker compose up -d`
+2. Open http://localhost:9091 in your browser
+3. Follow the initial setup wizard to configure the application
+
+## Environment Variable Notes
+
+    Configuration is file-based; env vars can override any setting using the AUTHELIA_ prefix
+
+## Volume Notes
+
+    /config – configuration.yml, users_database.yml, and the local SQLite storage
+
+## Network Notes
+
+Requires proxy network
+
+## Docker Run
+
+```bash
+docker run -d \
+  --name authelia \
+  -p 9091:9091 \
+  -e TZ=America/Vancouver \
+  -v /data/authelia/config:/config \
+  authelia/authelia:latest
+```
+
+## Additional Notes / Gotchas
+
+Authelia will not start without a valid `configuration.yml` in the config volume — generate one from the docs first (session secret, storage encryption key, and a users_database.yml are the minimum).
+Works as forward-auth with Nginx Proxy Manager.
