Blog posts are one of the pre-defined content types and ready use directly after you install Tanam.
You can upload and manage media files (currently only images) directly in Tanam CMS. Each uploaded image will be kept in its original format and also converted into a number of small to large scaled WebP versions for option of higher performance.
The CMS will notify you if you are in need of a composite index for any query that your templates are trying to perform. Clicking the notification link will take you to the Firebase console and automatically open the "click-to-create index" dialog.
