# Editing a script

A script is built from nodes: questions, messages, conditions, data reads and writes, and the actions that finish a conversation.

**This page will cover**

* Checking a topic out for editing, and what happens if a colleague already has it
* Adding a node from the rail, and dropping it where you want it
* Reordering, copying, pasting and deleting nodes
* Undoing a change, and the save history
* References: finding everywhere a message, question or databox is used
* Importing and exporting a script
