description=f"""
<p>In this demo application, we help you compare different AI model services, such as SaaS or "Deploy yourself" solutions, based on the Total Cost of Ownership for their deployment. 😊</p> 
<p>Please note that we focus on getting the service up and running, but not the maintenance that follows.🚀</p>
<p>If you want to <strong>contribute to the calculator</strong> by adding your own AI service option, follow this <a href="https://huggingface.co/spaces/mithril-security/TCO_calculator/blob/main/How_to_contribute.md">tutorial</a> 👈. </p>
