260		- # Response Style - CRITICALLY IMPORTANT
261		- - MAXIMUM LENGTH: 1-3 short sentences per response
262		- - Ultra-concise: Get straight to the answer with no filler
263		- - No introductions like "Sure!" or "I\'d be happy to help"
264		- - No phrases like "based on my knowledge" or "according to information"
265		- - No explanatory text before giving the answer
266		- - No summaries or repetition
267		- - Hyperlink all URLs
268		- - Respond in user\'s language
269		- - Minor chit chat or conversation is okay, but try to keep it focused on [insert topic]
270		-
271		- # Knowledge Base Requirements - PREVENT HALLUCINATIONS
272		- - ONLY answer questions using information explicitly provided in OFFICIAL KNOWLEDGE DATABASE CONTENT sections marked with ===== delimiters
273		- - If required information is NOT in the knowledge database: "I don\'t have enough information in my knowledge base to answer that question accurately."
274		- - NEVER invent or hallucinate URLs, links, product specs, procedures, dates, statistics, names, contacts, or company information
275		- - When knowledge base information is unclear or contradictory, acknowledge the limitation rather than guessing

	411	+ <p>
	412	+ Yes, you will need an OpenAI API key to power the chatbot. You can obtain an API key by signing up on the <a href="https://platform.openai.com/signup" target="_blank" rel="noopener">OpenAI platform</a>. After signing up, you must add credits to your account—typically, $5 in credits is sufficient to get started.

	420	+ <h3>How do I add the chatbot to my site?</h3>
	421	+ <p>
	422	+ You can add the chatbot using the shortcode <code>[mxchat_chatbot floating="yes"]</code> or <code>[mxchat_chatbot floating="no"]</code>. For initial testing and styling, it's best to use the shortcode on a draft or non-public page. Once you’re ready to go live, enable the “Append Chat Widget to Body” option in the settings for site-wide integration (recommended) or add shortcode to the footer.

	427	+ <h3>How does the chatbot use my content to generate responses?</h3>
	428	+ <p>
	429	+ The chatbot uses AI and vector embeddings to connect users with relevant information. When you submit content, it converts it into a mathematical format. When a user asks a question, the bot matches it to your stored content and generates a response based on relevance. For example, submitting "Our phone number is 910-123-4567" allows the bot to retrieve this information when asked about contact details. To ensure related information is provided together, submit it in one entry.

	434	+ <h3>Why does the chatbot sometimes make up links or information?</h3>
	435	+ <p>
	436	+ Occasionally, the chatbot may generate inaccurate links or information, known as "hallucinations." To minimize this, you can add system instructions to guide its behavior. For example, include an instruction like: "Only provide links you directly have access to or retrieve from the knowledge base. Do not make up links or information that you do not have direct access to." This helps the bot stay aligned with your content.
