 ### Loading OCELs & Viewing OCEL info
 When visiting the initial page of the tool, you can load an OCEL2 file by either choosing a custom OCEL2 file (XML/JSON) or selecting an OCEL2 file from the provided list (only available in the dev/docker setup and only if there are .json/.xml files in the `backend/data` folder).
 If the OCEL was loaded successfully, you will automatically be forwarded to the OCEL info view.
