-#### ⚠️ Advanced features
-For some advanced features (ex: Export as PDF) Docs relies on XL packages from BlockNote. These are licenced under GPL 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/env.md) for more information.

-# Installation
-If you want to install Docs you've come to the right place.
-Here are a bunch of resources to help you install the project.
-
-## Kubernetes
-We (Docs maintainers) are only using the Kubernetes deployment method in production. We can only provide advanced support for this method.
-Please follow the instructions laid out [here](/docs/installation/kubernetes.md).
-
-## Docker Compose
-We are aware that not everyone has Kubernetes Cluster laying around 😆. 
-We also provide [Docker images](https://hub.docker.com/u/lasuite?page=1&search=impress) that you can deploy using Compose. 
-Please follow the instructions [here](/docs/installation/compose.md). 
-⚠️ Please keep in mind that we do not use it ourselves in production. Let us know in the issues if you run into troubles, we'll try to help.
-
-## Other ways to install Docs
-Community members have contributed several other ways to install Docs. While we owe them a big thanks 🙏, please keep in mind we (Docs maintainers) can't provide support on these installation methods as we don't use them ourselves and there are two many options out there for us to keep track of. Of course you can contact the contributors and the broader community for assistance.
