+# SolFoundry Discord Bot
+
+Bounty notification bot for the SolFoundry AI Agent Marketplace.
+
+## Features
+
+- 🔔 **New Bounty Notifications** — Rich embeds posted automatically when new bounties appear
+- 🏆 **Leaderboard** — `/leaderboard` command shows top contributors
+- 🔍 **Bounty Search** — `/bounties` with tier and domain filters
+- ⚙️ **Personal Filters** — `/subscribe` to customize notification preferences
+- 📊 **Bot Status** — `/status` for uptime and poller info
+
+## Setup
+
+### 1. Create Discord Application
+
+1. Go to https://discord.com/developers/applications
+2. Create a new application
+3. Create a bot and copy the **Bot Token**
+4. Enable **Message Content Intent** and **Server Members Intent**
+5. Copy the **Application ID**
+
+### 2. Invite Bot to Server
+
+Use the OAuth2 URL generator with scopes: `bot`, `applications.commands`
+
+### 3. Configure Environment
+
+```bash
+# Required
+DISCORD_BOT_TOKEN=your-bot-token
+DISCORD_CHANNEL_ID=your-channel-id
+DISCORD_GUILD_ID=your-guild-id
+DISCORD_CLIENT_ID=your-application-id
+
+# Optional
+SOLFOUNDRY_API_URL=https://api.solfoundry.io
+```
+
+### 4. Run
+
+```bash
+npm install
+npm start
+```
+
+## Commands
+
+| Command | Description |
+|---------|-------------|
+| `/bounties [tier] [domain] [limit]` | List open bounties |
+| `/leaderboard [top]` | Show top contributors |
+| `/subscribe [min_tier] [min_reward] [domain]` | Set notification filters |
+| `/unsubscribe` | Remove notification filters |
+| `/status` | Show bot status |
+
