+This python application generates a pdf-file based calendar with images and associated texts for each day. It's designed to read images and texts from specified directories and display them in a calendar format. Per DIN A4 page 4 days get displayed.
-This Flask application generates a web-based calendar view with images and associated texts for each day. It's designed to read images and texts from specified directories and display them in a calendar format. The web-based pages can be printed to a pdf-file. This is easy, because every browser application has the option to print a page to a pdf-file. Per DIN A4 page 4 days get displayed.

 ## How It Works
-
-- The application serves a web page displaying a calendar.
 - Each day on the calendar can have an image and a text associated with it.
-- Images are read from `static/images/`, and text files are from `texts/`.
+- Images are read from `images/`, and text files are from `texts/`.
 - Files are matched based on their filenames, formatted as `YYYY-MM-DD`.
 - The calendar is dynamically generated based on available images and texts.
 - If an image or text is not available for a specific day, it will be displayed without that content.

 ## Notes
 
 - Text for each day should be concise. Lengthy texts may be truncated in the display to maintain the layout of the calendar.
-- You can customize the appearance and behavior of the calendar by modifying the HTML, CSS, and Flask application logic.
