# Build your first agent

A step-by-step tutorial: build a small digital agent that greets the customer, answers questions with AI (optionally from your own knowledge base), says goodbye, and runs on your website.

In this tutorial you build a small digital agent from scratch, test it and put it on a web page. It takes about 30 minutes and needs no programming.

## What you will build

```
START → MSG_WELCOME → ANS_MAIN ─ "goodbye" ──→ MSG_GOODBYE → END_DONE
                         ↑   └─ anything else ─→ AI_ASSISTANT ─┐
                         └─────────────────────────────────────┘
```

* **MSG\_WELCOME** greets the customer.
* **ANS\_MAIN** waits for the customer's message. When the customer says goodbye, the agent says goodbye and ends. Everything else is a question for the AI.
* **AI\_ASSISTANT** answers the question with a language model and returns to **ANS\_MAIN** for the next question – so the customer can ask as many questions as they like.

## Before you start

* You can sign in to Digital Studio with the **Admin** or **User** role – see [Sign in](/getting-started/sign-in.md).
* Have a look at [User Interface Basics](/digital-agent/conversation-flow/user-interface-basics.md) to find your way in the flow editor.

**The one rule to remember:** every node must lead somewhere. A node with an empty **Next** makes training fail. The steps below tell you which **Next** to fill in.
