 ## How can I find relevant information about scenarios on the OEP?
 
-:oep-icon-info: Our [scenario bundles](https://openenergyplatform.org/scenario-bundles/main) provide dedicated information about scenarios and their context. Context for example includes the study reports that deal with the scenario(s), the projection data available on the OEP that were created using the scenario(s), the sectors and technologies depicted and so on. These bundles are be based on RDF and the Open Energy Knowledge Graph (OEKG) and they are tied to the [Open Energy Ontology](https://openenergyplatform.org/ontology/) (OEO) for improving comparability across scenario bundles.
