+# Set variables
+
+Set variables to be used together with the system prompt for your LLM.
+
+---
+
+When configuring the system prompt for a chat model, variables play an important role in enhancing flexibility and reusability. With variables, you can dynamically adjust the system prompt to be sent to your model. In the context of RAGFlow, if you have defined variables in the **Chat Configuration** dialogue, except for the system's reserved variable `{knowledge}`, you are required to pass in values for them from RAGFlow's [HTTP API](../../references/http_api_reference.md#converse-with-chat-assistant) or through its [Python SDK](../../references/python_api_reference.md#converse-with-chat-assistant).
+
+:::danger IMPORTANT
+In RAGFlow, variables are closely linked with the system prompt. When you add a variable in the **Variable** section, include it in the system prompt. Conversely, when deleting a variable, ensure it is removed from the system prompt; otherwise, an error would occur.
+:::
+
+## Where to set variables
+
+Hover your mouse over your chat assistant, click **Edit** to open its **Chat Configuration** dialogue, then click the **Prompt Engine** tab. Here, you can work on your variables in the **System prompt** field and the **Variable** section:
+
+![set_variables](https://raw.githubusercontent.com/infiniflow/ragflow-docs/main/images/prompt_engine.jpg)
+
+## 1. Manage variables
+
+In the **Variable** section, you add, remove, or update variables.
+
+### `{knowledge}` - a reserved variable
+
+`{knowledge}` is the system's reserved variable, representing the chunks retrieved from the knowledge base(s) specified by **Knowledge bases** under the **Assistant settings** tab. If your chat assistant is associated with certain knowledge bases, you can keep it as is.
+
+:::info NOTE
+It does not currently make a difference whether you set `{knowledge}` to optional or mandatory, but note that this design will be updated at a later point.
+:::
+
+From v0.17.0 onward, you can start an AI chat without specifying knowledge bases. In this case, we recommend removing the `{knowledge}` variable to prevent unnecessary references and keeping the **Empty response** field empty to avoid errors.
+
+### Custom variables
+
+Besides `{knowledge}`, you can also define your own variables to pair with the system prompt. To use these custom variables, you must pass in their values through RAGFlow's official APIs. The **Optional** toggle determines whether these variables are required in the corresponding APIs:
+
+- **Disabled** (Default): The variable is mandatory and must be provided.
+- **Enabled**: The variable is optional and can be omitted if not needed.
+
+
+
+## 2. Update system prompt
+
+After you add or remove variables in the **Variable** section, ensure your changes are reflected in the system prompt to avoid inconsistencies and errors. Here's an example:
+
+```
+You are an intelligent assistant. Please answer the question by summarizing chunks from the specified knowledge base(s)...
+
+Your answers should follow a professional and {style} style.
+
+Here is the knowledge base:
+{knowledge}
+The above is the knowledge base.
+```
+
+:::tip NOTE
+If you have removed `{knowledge}`, ensure that you thoroughly review and update the entire system prompt to achieve optimal results.
+:::
+
+## APIs
+
+The *only* way to pass in values for the custom variables defined in the **Chat Configuration** dialogue is to call RAGFlow's [HTTP API](../../references/http_api_reference.md#converse-with-chat-assistant) or through its [Python SDK](../../references/python_api_reference.md#converse-with-chat-assistant).
+
+### HTTP API
+

 Retrieval accuracy is the touchstone for a production-ready RAG framework. In addition to retrieval-enhancing approaches like auto-keyword, auto-question, and knowledge graph, RAGFlow introduces an auto-tagging feature to address semantic gaps. The auto-tagging feature automatically maps tags in the user-defined tag sets to relevant chunks within your knowledge base based on similarity with each chunk. This automation mechanism allows you to apply an additional "layer" of domain-specific knowledge to existing datasets, which is particularly useful when dealing with a large number of chunks.
 
-To use this feature, ensure you have at least one properly configured tag set, specify the tag set(s) on the **Configuration** page of your knowledge base (dataset), and then re-parse your documents to initiate the auto-tag process. During this process, each chunk in your dataset is compared with every entry in the specified tag set(s), and tags are automatically applied based on similarity.

 ## Scenarios
 
-Auto-tagging applies in situations where chunks are so similar to each other that the intended chunks cannot be distinguished from the rest. For example, when you have a few chunks about iPhone and a majority about iPhone case or iPhone accessaries, it becomes difficult to retrieve the iPhone-specific chunks without additional information.
