+# Multi-Turn Experiment Example
+
+The example in this folder demonstrates how to use [create_experiment](https://docs.galileo.ai/sdk-api/python/reference/experiments#create_experiment) to compute a session-level metric for a multi-turn conversation. 
+
+## Setup Instructions
+
+### 1. Create and Activate Virtual Environment
+
+```bash
+# Navigate to the example folder
+cd python/experiments/multi-turn
+
+# Create virtual environment
+python -m venv venv
+
+# Activate virtual environment
+source venv/bin/activate
+```
+
+### 2. Install Dependencies
+
+Run
+
+```bash
+pip install -r requirements.txt
+```
+
+### 3. Configure Environment Variables
+
+Your `.env` should look like this. Feel free to follow the `.env.example` and enter your credentials
+
+```bash
+
+# Required: Your Galileo API key
+GALILEO_API_KEY="your-galileo-api-key"
+
+# Required: Galileo project name
+GALILEO_PROJECT="your-galileo-project"
+
+# Provide the console url below if you are not using app.galileo.ai
+# GALILEO_CONSOLE_URL="your-galileo-console-url"
+```
+
+### 4. Add Integration in Galileo Console
+
+The session-level metric in this example uses an LLM. 
+
+Make sure that you've configured a valid LLM integration in the Galileo console.
+
+Related documentation: [Configure an LLM integration](https://docs.galileo.ai/getting-started/evaluate-and-improve/evaluate-and-improve#configure-an-llm-integration)
+
+## Basic Example
+
+Run the basic example:
+
+```bash
+python basic-example.py
+```
+
+The `METRIC_NAME` variable in this script cites a session-level metric.
+
+Pre-defined session-level metrics include:
+
+- `GalileoMetrics.conversation_quality`
+- `GalileoMetrics.action_completion`
+- `GalileoMetrics.action_advancement`
+- `GalileoMetrics.agent_efficiency`
+- `GalileoMetrics.context_adherence`
+- `GalileoMetrics.context_relevance`
+- `GalileoMetrics.tool_error_rate`
+
+Related documentation: [Metrics Comparison](https://docs.galileo.ai/concepts/metrics/metric-comparison)
+
+Optionally, you can define your own custom session-level metric in the Galileo Console UI, and then add the custom metric name. 
+
+![Example custom session-level boolean metric](screenshot-custom-session-level-boolean-metric.png)
+
+## Troubleshooting
+
+Visit the "Sessions" tab of the Experiment in the Galileo Console to confirm the status of the metric computation.
+
+![Troubleshooting auth error](screenshot-session-level-metric-auth-error.png)
+
+If you see an auth error, go to the metric details and make sure that a [valid integration](https://docs.galileo.ai/getting-started/evaluate-and-improve/evaluate-and-improve#configure-an-llm-integration) has been configured.
