-⚠️ For some advanced features (ex: Export as PDF) Docs relies on XL packages from BlockNote. These are licenced under AGPL-3.0 and are not MIT compatible. You can perfectly use Docs without these packages by setting the environment variable `PUBLISH_AS_MIT` to true. That way you'll build an image of the application without the features that are not MIT compatible. Read the [environment variables documentation](/docs/docs/env.md) for more information.
