+# Discord Bot Starter
+
+This is a starter template for creating a Discord bot using the Solana Agent Kit by Send AI.
+
+## Setup
+
+### Prerequisites
+
+- Node.js (v20 or higher)
+- pnpm (v9 or higher)
+- A Discord account
+- A Solana account keypair
+
+### Step 1: Create a Discord Bot
+
+1. Go to the [Discord Developer Portal](https://discord.com/developers/applications).
+2. Click on "New Application" and give your application a name.
+3. Navigate to the "Bot" tab on the left sidebar and click "Add Bot".
+4. Under the "Token" section, click "Copy" to copy your bot token.
+
+### Step 2: Fill Out Environment Variables
+
+Create a `.env` file in the root directory of the project and fill it out with the following variables:
+
+- `DISCORD_BOT_TOKEN`: Paste the bot token you copied from the Discord Developer Portal.
+- `SOLANA_PRIVATE_KEY`: Enter your Solana private key. This is required for interacting with the Solana blockchain.
+- `SOLANA_RPC_URL`: Provide the RPC URL for connecting to the Solana network. You can use a public RPC URL or your own.
+- `OPENAI_API_KEY`: Input your OpenAI API key if you plan to use OpenAI services within your bot. You can obtain this key from the OpenAI platform.
+
+### Step 3: Install Dependencies and Start the Bot
+
+1. Open a terminal and navigate to the root directory of the project.
+2. Run the following command to install the project dependencies:
+   ```sh
+   pnpm install
+   ```
+3. After the installation is complete, start the bot by running:
+   ```sh
+   pnpm start
+   ```
+4. Once the bot is running, open Discord and send a direct message (DM) to your bot to ensure it is working correctly.
