## Step 1. Download the client

Instructions are available on the [installation page](https://tuna.am/en/docs/guides/install.md).

## Step 2. Run a server on the Flask framework

Server code example (explanations can be found in the [official documentation](https://flask.palletsprojects.com/en/3.0.x/quickstart/)):

```python
from flask import Flask

app = Flask(__name__)

@app.route("/")
def hello_world():
    return "<p>Hello, World!</p>"

```

## Step 3. Run tuna

Flask uses port 5000 by default:

```bash
tuna http 5000

```
