## Importing Requirements

Any requirement build from another notebook in the same Folder can be reused. Once you import a new requirement, it will build. Once done you will have an option to activate it. Below video shows how you can reuse requirements.&#x20;

There are many requirements available when you open a Notebook, you can activate any of these requirements to start.
