# Phase library You can save completed phases in an experiment to the phase library so you can reuse them in another experiment. To do this, click on the **Phase Library** button, then type a name for the phase and click on **Add to library**. Saving completed phases to the phase library is useful as you can re-use a phase in another experiment. --- # 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.
