+A federated mobile-first event RSVP platform that lets you create events, share unique URLs, and collect RSVPs without any registration required. With built-in federation, discover and share events across a decentralized network of instances.
 
 ### ✨ Features
 
-- **🎯 Instant Event Creation** - Create events in seconds with our streamlined form. No accounts, no waiting, just pure efficiency.
-- **🔗 One-Click Sharing** - Each event gets a unique, memorable URL. Share instantly via any platform or messaging app.
-- **🔍 All-in-One Clarity** - No more scrolling through endless chats and reactions. See everyone's availability and responses neatly in one place.
-- **📅 iCal Integration** - One-tap add-to-calendar via ICS/webcal links. Works with Apple Calendar, Google Calendar, and Outlook, with automatic time zone handling.
-- **👤 No Hassle, No Sign-Ups** - Skip registrations and endless forms. Unlike other event platforms, you create and share instantly — no accounts, no barriers.
-- **🛡️ Smart Limits** - Choose between unlimited RSVPs or set a limited capacity. Perfect for any event size.
-- **✨ Effortless Simplicity** - Designed to be instantly clear and easy. No learning curve — just open, create, and go.

 Your app will be available at `http://localhost:5173`. You can use the Makefile commands to run the application or the database, eg.: `make db-only`.
 
 Use the `database/seed.sql` if you want to populate your database with dummy data.
 
+### Federation
+
+Cactoide supports federation, allowing multiple instances to share and discover public events across the network. This enables users to discover events from other Cactoide instances, creating a decentralized event discovery network.
+
+<p align="center">
+  <img alt="Federation Example" src="./docs/federation_example.png" width="840">
+</p>
+
+#### How it works
+
+Federation is managed through the `federation.config.js` file, which contains:
+
+- **Instance name**: The display name for your instance when exposing events to the federation
+- **Instance list**: An array of federated instance URLs. Add instance URLs here to discover events from other federated instances.
+
+```javascript
+const config = {
+	name: 'Cactoide Genesis',
+	instances: [{ url: 'js-meetups.seattle.io' }, { url: 'ai-events.seattle.com' }]
+};
+```
+
+#### Opt-in
+
+To enable federation on your instance, you need to:
+
+1. **Set the environment variable**: Add `FEDERATION_INSTANCE=true` to your `.env` file. This enables the federation API endpoints on your instance.
+
+2. **Configure your instance name**: Update the `name` field in your `federation.config.js` file to set your instance's display name.
+
+Your instance will automatically expose:
+
+- `/api/federation/events` - Returns all public events from your instance
+- `/api/federation/info` - Returns your instance name and public events count
+
+#### Adding your instance
+
+To add your instance to the global federation list (so other instances can discover your events):
+
+1. Fork the [Cactoide repository](https://github.com/polaroi8d/cactoide)
+2. Add your instance URL to the `instances` array in `federation.config.js`:
+3. Open a pull request to the main repository
+
+Once merged, your instance will appear in the federation network, and other instances will be able to discover and display your public events.
+
+You can view all registered federated instances in the main repository: `federation.config.js` file.

+# Cactoide
+
+> A federated mobile-first event RSVP platform built with SvelteKit. Cactoide is an open-source alternative to big tech event platforms like Meetup.com, Eventbrite, and Luma. It allows users to create events, share unique URLs, and collect RSVPs without any registration required. Features include built-in federation for decentralized event discovery across multiple instances, iCal integration, smart capacity limits, and a no-signup approach. The platform uses PostgreSQL with Drizzle ORM, implements federation via configurable instance lists, and supports multiple languages through a simple i18n system.
+
+Cactoide is an open-source event management platform licensed under AGPL-3.0, designed as a privacy-focused alternative to centralized event platforms. Unlike Meetup.com, Eventbrite, Luma, and other big tech solutions, Cactoide requires no user accounts, collects minimal data, and operates on a federated model that gives users control over their events and data. Events can be public, private, or invite-only. The platform supports both limited and unlimited RSVP capacity.
+
+## Architecture
+
+The project is built with:
+- **Frontend**: SvelteKit 5 with TypeScript, Tailwind CSS
+- **Backend**: SvelteKit server routes and API endpoints
+- **Database**: PostgreSQL with Drizzle ORM
+- **Deployment**: Docker and Docker Compose support
+
+Key architectural decisions:
+- File-based routing (SvelteKit conventions)
+- Server-side rendering for all pages
+- Cookie-based user identification (no authentication system)
+- Federation via HTTP API endpoints between instances
+
+## API Endpoints
+
+- [Health Check](/api/healthz): Returns instance health status and response time in milliseconds
+- [Federation Events](/api/federation/events): Returns all public events from the instance (requires FEDERATION_INSTANCE env variable)
+- [Federation Info](/api/federation/info): Returns instance name and public events count (requires FEDERATION_INSTANCE env variable)
+
+## Database Schema
+
+The database uses three main tables:
+- **events**: Stores event information (id, name, date, time, location, type, visibility, attendee_limit, user_id)
+- **rsvps**: Stores RSVP responses (id, event_id, name, user_id, created_at)
+- **invite_tokens**: Stores invite tokens for invite-only events (id, event_id, token, expires_at)
+
+Event visibility can be: public, private, or invite-only. Event types can be: limited or unlimited.
+
+## Federation
+
+Federation allows multiple Cactoide instances to share and discover public events. Configuration is managed through `federation.config.js` which contains:
+- Instance name (display name for the instance)
+- Instance list (array of federated instance URLs to discover events from)
+
+To enable federation on an instance:
+1. Set `FEDERATION_INSTANCE=true` environment variable
+2. Configure instance name in `federation.config.js`
+3. Add other instance URLs to the instances array to discover their events
+
+Federated instances are displayed at `/instance` with health status, response times, and event counts.
+
+## Routes
+
+- `/` - Landing page (can be disabled with PUBLIC_LANDING_INFO=false)
+- `/create` - Event creation form
+- `/discover` - Public events discovery page with search and filters
+- `/event/[id]` - Individual event page with RSVP functionality
+- `/instance` - Federation instances status page
+
+## Code Structure
+
+### src/routes/
+SvelteKit file-based routing system. Each folder represents a route, with `+page.svelte` for UI and `+page.server.ts` for server-side data loading.
