# Nodes To build virtual agents on our platform you can utilize the boxes you see on the left side of the page. The boxes are called **nodes** and are the building blocks of the conversation. Each of them has its own purpose, and together they create the conversational flow. You can click on a box, drag it into the middle of the page, and can edit it accordingly by clicking on it again. It will open up on the right side of the page. {% hint style="info" %} *In order to create a flow, you have to connect the nodes to one another. Please connect them from the exit point of one module to the entry point of another.* {% endhint %} ![](https://3877181490-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-L_81A0PNZfdawu_TPAO%2Fuploads%2Feu4SsWMBmPPZi4AhAUe9%2FNodes.gif?alt=media\&token=faecb462-5054-4fc9-8cdd-2a775e831e07) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
