+This Ansible role deploys **Nginx** as a high-performance [reverse proxy](https://en.wikipedia.org/wiki/Reverse_proxy) in front of Docker-hosted services.  
+It provides automatic TLS integration, WebSocket support, and a flexible templating system for per-application configuration.

-- https://www.bogotobogo.com/DevOps/Docker/docker/compose/Nginx-Reverse-Proxy-Multiple-Containers.php
+## Overview
+
+Optimised for Arch Linux, the role installs Nginx, prepares opinionated configuration snippets and exposes a simple interface for other roles to drop in new virtual-hosts.  
+It plays well with **Let’s Encrypt**, **OAuth2 Proxy**, and your existing Docker stack.
+
+## Purpose
+
+The goal of this role is to deliver a **hassle-free, production-ready reverse proxy** for self-hosted containers, suitable for homelabs and small-scale production workloads.
+
+## Features
+
+- **Automatic TLS & HSTS** — integrates with the *nginx-https* role for certificate management.  
+- **Flexible vHost templates** — *basic* and *ws_generic* flavours cover standard HTTP and WebSocket applications.  
+- **Security headers** — sensible defaults plus optional X-Frame-Options / CSP based on application settings.  
+- **WebSocket & HTTP/2 aware** — upgrades, keep-alive tuning, and gzip already configured.  
+- **OAuth2 gating** — drop-in support when *docker-oauth2-proxy* is present.  
+- **Modular includes** — headers, locations, and global snippets are factored for easy extension.

-# Nginx Domain Setup Role 🚀
+# Nginx Domain Setup 🚀
 
-This role streamlines your Nginx configuration by performing several essential tasks:
+## Description
 
-- **Modify Nginx configuration** with the `nginx-modifier-all` role.
-- **Request and receive HTTPS certificates** using the `nginx-https-get-cert` role.
-- **Deploy a domain configuration file** from a Jinja2 template.
-- **Optionally secure your domain** with OAuth2 via the `docker-oauth2-proxy` role if enabled.
+This role bootstraps **per-domain Nginx configuration**: it requests TLS certificates, applies global modifiers, deploys a ready-made vHost file, and can optionally lock down access via OAuth2.
 
-## Author
+## Overview
 
-Developed by [Kevin Veen-Birkenbach](https://www.veen.world) 😎
+A higher-level orchestration wrapper, *nginx-domain-setup* ties together several lower-level roles:
 
----
+1. **`nginx-modifier-all`** – applies global tweaks and includes.  
+2. **`nginx-https-get-cert`** – obtains Let’s Encrypt certificates.  
+3. **Domain template deployment** – copies a Jinja2 vHost from *nginx-docker-reverse-proxy*.  
+4. **`docker-oauth2-proxy`** *(optional)* – protects the site with OAuth2.
 
-Happy automating! 🎉
+The result is a complete, reproducible domain rollout in a single playbook task.
+
+## Purpose
+
+Provide **one-stop, idempotent domain provisioning** for Nginx-based homelabs or small production environments.
+
+## Features
+
+- **End-to-end TLS** — certificate retrieval and secure headers included.  
+- **Template-driven vHosts** — choose *basic* or *ws_generic* flavours (or your own).  
+- **Conditional OAuth2** — easily toggle authentication per application.  
+- **Handler-safe** — automatically triggers an Nginx reload when templates change.  
+- **Composable** — designed to be called repeatedly for many domains.
