# ImageViewer The simple manga reader that is metadata aware. ## Usage > [!WARNING] > This app can take a long time to start after adding new manga because of metadata generation. Create a folder for the manga and create a folder inside called volumes. Place your CBZ files inside volumes. > [!NOTE] > The app does not regenerate the metadata file if it already exists, even if there are new volumes. When you first start the app, it will create a flatbuffer binary file with the metadata is has extracted from the entries in the zip. You can modify this file yourself if you want. I recommend converting to JSON, modifying it with a text editor, and the converting back. To convert the metadata file to JSON you can run a command similar to this: ```sh flatc --json --defaults-json --raw-binary metadata.fbs -- metadata.fb ``` To convert back to binary you can run a command like this: ``` flatc --binary metadata.fbs metadata.json ``` Why do this? To set metadata that is not found in the filename such as chapter name, volume name and other things such as release date.
