53 + - If a visitor asks for a purchase link or further information, provide them with this link: [Insert Purchase Link Here]. Always ensure that the link is relevant and directly related to the website\'s offerings.
54 + - Keep your responses short, concise, and to the point. Provide clear and direct answers suitable for a chatbot interaction.
55 + - If you reference specific content, provide a hyperlink to the relevant page using hypertext. Avoid including links that do not directly relate to the content or answer the visitor\'s query.

290 + You can add the chatbot to your site using the <code>[mxchat_chatbot floating="yes"]</code> or <code>[mxchat_chatbot floating="no"]</code> shortcode. Additionally, you can automatically append the chatbot to your site’s body element from the settings page.
291 + </p>
292 + <p>
293 + Please note that you must have an OpenAI API key to use the chatbot. You can obtain an API key from the <a href="https://platform.openai.com/signup" target="_blank">OpenAI website</a>. It's easy to sign up, and you'll need to add credits to your account before using the chatbot. Generally, as little as $5 in credits is sufficient to get started.
