+
+## Getting Started
+
+### Prerequisites
+
+- [Bun](https://bun.sh/) runtime
+- Discord bot token
+- Replicate API token
+
+### Environment Variables
+
+Create a `.env` file:
+
+```env
+DISCORD_TOKEN=your_discord_token
+REPLICATE_API_TOKEN=your_replicate_token
+```
+
+### Installation
+
+```bash
+bun install
+```
+
+### Database Setup
+
+```bash
+# Generate migrations
+bun run db:generate
+
+# Run migrations
+bun run db:migrate
+```
+
+### Running
+
+```bash
+# Development (with hot reload)
+bun run dev
+
+# Production
+bun run start
+
+# Build
+bun run build
+```
+
+## Adding New Features
+
+### Adding a Command
+
+1. Create a new file in `src/commands/definitions/`:
+
+```typescript
+import { SlashCommandBuilder } from "discord.js";
+import type { Command } from "../types";
+
+const command: Command = {
+  data: new SlashCommandBuilder()
+    .setName("mycommand")
+    .setDescription("Description"),
+  category: "fun",
+  execute: async (interaction) => {
+    await interaction.reply("Hello!");
+  },
+};
+
+export default command;
+```
+
+Commands are auto-loaded from the `definitions/` folder.
+
+### Adding an Event Handler
+
+1. Create a new file in `src/events/handlers/`:
+
+```typescript
+import { Events } from "discord.js";
+import type { EventHandler } from "../types";
+
+export const myEventHandler: EventHandler<"eventName"> = {
+  name: Events.EventName as "eventName",
+  once: false,
+  execute: async (client, ...args) => {
+    // Handle event
+  },
+};
+```
+
+2. Register it in `src/events/register.ts`
+
+### Adding a New AI Provider
+
+1. Implement the `AiProvider` interface in `src/services/ai/`:
+
+```typescript
+import type { AiProvider, AiResponse, AskOptions } from "./types";
+
+export class MyProvider implements AiProvider {
+  async health(): Promise<boolean> {
+    return true;
+  }
+
+  async ask(options: AskOptions): Promise<AiResponse> {
+    // Implementation
+  }
+}
+```
+
+2. Use it in `AiService` constructor
+
+## Architecture Principles
+
+- **Separation of Concerns**: Each module has a single responsibility
+- **Dependency Injection**: Services can be swapped via interfaces
+- **Repository Pattern**: Database access through repositories
+- **Event-Driven**: Discord events are handled by dedicated handlers
+- **Feature Modules**: Related functionality grouped together
