 ## Features
 
-- 🔐 **Authentication** — Login, remember me, forced password change on first login
+### Messaging
-- 💬 **Real-time messaging** — WebSocket (Socket.io) powered chat
+- **Real-time messaging** — WebSocket-powered (Socket.io); messages appear instantly across all clients
-- 👥 **Public channels** — Admin-created, all users auto-joined
+- **Image attachments** — Attach and send images; auto-compressed client-side before upload
-- 🔒 **Private groups** — User-created, owner-managed
+- **Message replies** — Quote and reply to any message with an inline preview
-- 📷 **Image uploads** — Attach images to messages
+- **Emoji reactions** — Quick-react with common emojis or open the full emoji picker; one reaction per user, replaceable
-- 💬 **Message quoting** — Reply to any message with preview
+- **@Mentions** — Type `@` to search and tag users with autocomplete; mentioned users receive a notification
-- 😎 **Emoji reactions** — Quick reactions + full emoji picker
+- **Link previews** — URLs are automatically expanded with Open Graph metadata (title, image, site name)
-- @**Mentions** — @mention users with autocomplete, they get notified
+- **Typing indicators** — See when others are composing a message
-- 🔗 **Link previews** — Auto-fetches OG metadata for URLs
+- **Image lightbox** — Tap any image to open it full-screen with pinch-to-zoom support
-- 📱 **PWA** — Install to home screen, works offline
+
-- 👤 **Profiles** — Custom avatars, display names, about me
+### Channels & Groups
-- ⚙️ **Admin settings** — Custom logo, app name
+- **Public channels** — Admin-created; all users are automatically added
-- 👨‍💼 **User management** — Create, suspend, delete, bulk CSV import
+- **Private groups / DMs** — Any user can create; membership is invite-only by the owner
-- 📢 **Read-only channels** — Announcement-style public channels
+- **Read-only channels** — Admin-configurable announcement-style channels; only admins can post
+- **Support group** — A private admin-only group that receives submissions from the login page contact form
+
+### Users & Profiles
+- **Authentication** — Email/password login with optional Remember Me (30-day session)
+- **Forced password change** — New users must change their password on first login
+- **User profiles** — Custom display name, avatar upload, About Me text

+### Notifications
+- **In-app notifications** — Mention alerts with toast notifications
+- **Unread indicators** — Private groups with new unread messages are highlighted and bolded in the sidebar
+- **Web Push notifications** — Badge and push notifications for mentions and new private messages when the app is backgrounded or closed (requires HTTPS)
+
+### Admin & Settings
+- **User Manager** — Create, suspend, activate, delete users; reset passwords; change roles
+- **Bulk CSV import** — Import multiple users at once from a CSV file
+- **App branding** — Customize app name, logo, New Chat icon, and Group Info icon via the Settings panel
+- **Reset to defaults** — One-click reset of all branding customizations

+
+### PWA
+- **Installable** — Install to home screen on mobile and desktop via the browser install prompt
+- **Dynamic app icon** — Uploaded logo is automatically resized to 192×192 and 512×512 and used as the PWA shortcut icon
+- **Dynamic manifest** — App name and icons in the PWA manifest update live when changed in Settings
+- **Offline fallback** — Basic offline support via service worker caching
+
+### Contact Form
+- **Login page contact form** — A "Contact Support" button on the login page opens a form (name, email, message, math captcha) that posts directly into the admin Support group

-## Quick Start
+## Tech Stack
 
-### Prerequisites
+| Layer | Technology |
-- Docker & Docker Compose
+|---|---|
-
+| Backend | Node.js, Express, Socket.io |
-### 1. Build a versioned image
+| Database | SQLite (better-sqlite3) |
-
+| Frontend | React 18, Vite |
-```bash
+| Image processing | sharp |
-# Build and tag as v1.0.0 (also tags :latest)
+| Push notifications | web-push (VAPID) |
-./build.sh 1.0.0
+| Containerization | Docker, Docker Compose |
-
+| Reverse proxy / SSL | Caddy (recommended) |
-# Build latest only
-./build.sh
-```
-
-### 2. Deploy with Docker Compose
-
-```bash
-cp .env.example .env
-# Edit .env — set TEAMCHAT_VERSION, admin credentials, JWT_SECRET
-nano .env
-
-docker compose up -d
-
-# View logs
-docker compose logs -f
-```
-
-App will be available at **http://localhost:3000**
 
 ---
 
-## Release Workflow
+## Requirements
 
-TeamChat uses a **build-then-run** pattern. You build the image once on your build machine (or CI), then the compose file just runs the pre-built image — no build step at deploy time.
+- **Docker** and **Docker Compose v2**
+- A domain name with DNS pointed at your server (required for HTTPS and Web Push notifications)
+- Ports **80** and **443** open on your server firewall (if using Caddy for SSL)

-### Build script usage
+## Building the Image
+
+All builds use `build.sh`. No host Node.js installation is required — `npm install` and the Vite build run inside Docker.
