 ## Why use Docs ❓
 
-⚠️ **Note that Docs provides docs/pdf exporters by loading [two BlockNote packages](https://github.com/suitenumerique/docs/blob/main/src/frontend/apps/impress/package.json#L22C7-L23C53), which we use under the AGPL-3.0 licence. Until we comply with the terms of this license, we recommend that you don't run Docs as a commercial product, unless you are willing to sponsor [BlockNote](https://github.com/TypeCellOS/BlockNote).**

+⚠️ During Docs installation, you will be prompted if you want to install them or not. Please ensure to fulfill your obligation regarding BlockNoteJS licensing (see https://github.com/TypeCellOS/BlockNote/blob/main/packages/xl-pdf-exporter/LICENSE and https://www.blocknotejs.org/about#partner-with-us). Note that Docs works perfectly fine without these export features.
