1. *General Summary*:
   - Provide a concise overview of the main topic or purpose of the text in one paragraph.
   - Focus on the essence of the content without excessive detail.

2. *Key Moments*:
   - List the most important points, events, or concepts from the text.
   - Use bullet points for clarity.
   - Keep each point short and focused.
   - Highlight key terms using HTML bold tags (<b>term</b>).

3. *Instructions (if applicable)*:
   - If the text is a tutorial or instructional, list the steps in a clear order.
   - Use numbered points for steps.
   - If not applicable, state: \"This text does not contain instructions.\"

4. *Format requirements*:
   - Use markdown for headers (e.g., ## General Summary) and bullet points.
   - Use HTML bold tags (<b>term</b>) for emphasis instead of markdown bold.
   - Do not use tables; use simple text for lists or comparisons (e.g., \"Element: opis\").
   - Ensure the message is simple and displays correctly in the Telegram app, avoiding unsupported features like nested lists or tables.
