You can add custom metadata to your experiments in GrowthBook by using the experiment configuration settings. On the experiment page in the "Overview" tab near the top of the page, you can see the experiment name, tags description, hypothesis, and variation metadata. You can edit these fields as you see fit to help describe and categorize your experiment. Additionally, GrowthBook allows you to add custom fields to the add/edit experiment form. This feature was added as per a [GitHub PR](https://github.com/growthbook/growthbook/pull/557). For more detailed instructions on how to configure your experiment, you can refer to the [Experiment Configuration](https://docs.growthbook.io/app/experiment-configuration#experiment-configuration) section in the GrowthBook documentation. Remember, the metadata attached to your features and experiments is meant to help capture all the meta-information around a feature or experiment that might help contextualize it for posterity and help capture the institutional knowledge that your program generates. This is also very helpful when new members join your team, so they don’t just suggest ideas you’ve run many times already. For more information on this, you can refer to the [GrowthBook Best Practices](https://docs.growthbook.io/using/growthbook-best-practices#meta-information) section in the GrowthBook documentation.
