# Nodes The **Nodes** section gathers lines and remote nodes for the PR4 protocol. A line refers to a PR4 server, while remote nodes are the connections to client applications. First of all, the PR4 node must be created, then the line and the remote node can be added. Details on how to **create a PR4 node**, **line** and **remote node** are available on the next page. --- # 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.
