# Build a Q&A knowledge base
> Add question-and-answer pairs for the exact phrasing customers use.
**Q\&A** is one of four source types on the **Content** tab. Define a question, its common variations, and one fixed answer. It is built for the phrasing you know customers actually use that is not written down anywhere on your site or in your documents.
## Add a Q\&A pair
1. Open the **Content** tab and click **Add Content** in the top-right corner.
2. Choose **Add Q\&A** from the dropdown.
3. Give the entry a **name**.
4. Enter the **question** — including any phrasing variations customers commonly use for it.
5. Enter the **answer** the employee should give.
6. Save. The entry is queued for the next training cycle; see [Keep knowledge accurate](/help/ai-employees/content/keep-knowledge-accurate).
Rather than relying on the employee to infer the right answer from a larger document, a Q\&A entry gives it an exact question paired with an exact answer, referenced whenever that question — or something sufficiently close to it — comes up in a live conversation.
## When Q\&A is the right source
Q\&A works best for facts that should never drift — pricing, hours, shipping windows, refund windows — where you want one exact, approved answer regardless of how the question is worded.
| Source | Best for |
| --------------------------------------------------------------- | ------------------------------------------------------------------------------------------- |
| **Q\&A** | Facts with one correct answer that should not vary, phrased the way customers actually ask. |
| [**Links**](/help/ai-employees/content/add-your-website) | Broad static content already published on your site. |
| [**Documents**](/help/ai-employees/content/upload-documents) | Structured content already written up in a file — spec sheets, policies, guides. |
| [**Text**](/help/ai-employees/content/add-plain-text-knowledge) | One-off notes that do not exist as a page or file yet. |
Combine Q\&A with links and documents rather than choosing one — Q\&A locks down the exact answers customers ask about most, while links and documents give the employee broader coverage for everything else.
