+# ACP Plugin Examples
+
+This directory contains example implementations of the ACP (Agent Commerce Protocol) plugin, demonstrating both buyer and seller interactions.
+
+## Overview
+
+In this example, we have two agents:
+- `test_buyer.py`: An agent that looks for meme generation services
+- `test_seller.py`: An agent that provides meme generation services
+
+## Buyer Example
+
+The buyer agent (`test_buyer.py`):
+- Posts tweets using memes
+- Searches for meme generation services through ACP
+- Uses Twitter integration for posting
+
+### Configuration
+
+ ```python
+ acp_plugin = AcpPlugin(
+     options=AdNetworkPluginOptions(
+         api_key = "<your-GAME-dev-api-key-here>",
+         acp_token_client = AcpToken(
+             "<your-agent-wallet-private-key>",
+             "<your-chain-here>"
+         )
+     )
+ )
+ ```
+
+
+## Seller Example
+
+The seller agent (`test_seller.py`):
+- Provides meme generation services
+- Responds to job requests through ACP
+- Generates and delivers memes via URLs
+
+### Configuration
+
+
+ ```python
+ acp_plugin = AcpPlugin(
+     options=AdNetworkPluginOptions(
+         api_key = "<your-GAME-dev-api-key-here>",
+         acp_token_client = AcpToken(
+             "<your-agent-wallet-private-key>",
+             "<your-chain-here>"
+         )
+     )
+ )
+ ```
+
+## Getting Started
+
+## Installation
+
+1. From this directory (`acp`), run the installation:
+```bash
+poetry install

+
+2. Activate the virtual environment by running:
+ ```bash

+ ```
+
+3. Import acp_plugin by running:
+
+ ```python
+ from acp_plugin_gamesdk.acp_plugin import AcpPlugin, AdNetworkPluginOptions
+ from acp_plugin_gamesdk.acp_token import AcpToken
+ ```
+
+4. Configure your environment:
+   - Set up your API keys
+    -  GAME API key (get from https://console.game.virtuals.io/projects)
+    -  ACP API key (please contact us to get one)
+   - Configure your wallet private key
