- [ANSWER node](https://docs.borndigital.ai/digital-agent/conversation-flow/nodes-explained/answer-node.md): Use the Answer node when you need a response from the customer: it waits for the input, recognises the intent and decides where the conversation goes.
- [DECISION node](https://docs.borndigital.ai/digital-agent/conversation-flow/nodes-explained/decision-node.md): Use the Decision node to branch the conversation based on conditions over variables.
- [FUNCTION node](https://docs.borndigital.ai/digital-agent/conversation-flow/nodes-explained/function-node.md): Use the Function node to run tools, call back-end systems and set or reset variables in the background.
- [AI node](https://docs.borndigital.ai/digital-agent/conversation-flow/nodes-explained/ai-node.md): The AI node lets a large language model answer the user, use tools and decide where the conversation goes next.

- [Build your first agent](https://docs.borndigital.ai/digital-agent/building-new-projects.md): 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.
- [Step 1 – Create the project](https://docs.borndigital.ai/digital-agent/building-new-projects/step-1-create-the-project.md): Create an empty Digital Agent project and open it in the flow editor.
- [Step 2 – Welcome the customer and wait for a message](https://docs.borndigital.ai/digital-agent/building-new-projects/step-2-welcome-and-wait-for-a-message.md): Add a welcome message, an Answer node that waits for the customer, and a goodbye path that ends the conversation.
- [Step 3 – Answer questions with AI](https://docs.borndigital.ai/digital-agent/building-new-projects/step-3-answer-questions-with-ai.md): Add an AI node that answers every other message and returns to the Answer node, so the customer can keep asking.
- [Step 4 – Add your own knowledge (optional)](https://docs.borndigital.ai/digital-agent/building-new-projects/step-4-add-your-own-knowledge.md): Optional: let the AI node answer from your own documents with a knowledge base. Uses a small UNESCO sample.
