+# Traefik
+
+## Overview
+
+Modern reverse proxy and load balancer designed for microservices and Docker environments.
+
+## Project Details
+
+-   **Project Repository:** [GitHub](https://github.com/traefik/traefik)
+-   **Container Image:** [traefik](https://hub.docker.com/_/traefik)
+-   **Documentation:** [doc.traefik.io](https://doc.traefik.io/traefik/)
+-   **Reverse Proxy Port:** `8080` (dashboard)
+
+## Getting Started
+
+1. Start the container: `docker compose up -d`
+2. Open http://localhost:8080 in your browser
+3. Follow the initial setup wizard to configure the application
+
+## Environment Variable Notes
+
+    TRAEFIK_HTTP_PORT / TRAEFIK_HTTPS_PORT – entrypoint ports
+    TRAEFIK_DASHBOARD_PORT – dashboard/API port
+
+## Volume Notes
+
+    /var/run/docker.sock – read-only Docker socket for service discovery
+    /letsencrypt – ACME certificate storage
+
+## Network Notes
+
+Requires proxy network
+
+## Docker Run
+
+```bash
+docker run -d \
+  --name traefik \
+  -p 80:80 -p 443:443 -p 8080:8080 \
+  -v /var/run/docker.sock:/var/run/docker.sock:ro \
+  traefik:v3 \
+  --api.insecure=true --providers.docker=true \
+  --providers.docker.exposedbydefault=false \
+  --entrypoints.web.address=:80 --entrypoints.websecure.address=:443
+```
+
+## Additional Notes / Gotchas
+
+This repo assumes Nginx Proxy Manager as the main reverse proxy — running Traefik alongside it will conflict on ports 80/443 unless you change them.
+`--api.insecure=true` exposes the dashboard without auth; do not expose port 8080 publicly.
