+### Embedding Model Configuration
+
+App-Controller need to use two types of model, including the chat model and the embedding model. These models need api key to be
+called.
+In our system, the user of your application need to provide api keys of two types model. In addition, the developer of application
+need to provide the api key of the embedding model for pre-building the index.
+
+- **Chat model**: It is used to reason the suitable API for the user's input. All users of your application need to send api key
+  of selected chat model to the App-Controller. Then, the chat model will be called by the api key.
+- **Embedding model**: For developer of application, you need to provide the api key of the embedding model for pre-building the
+  index on available apis and other knowledge. For user of your application, the api key of the embedding model will be used to
+  embed the user's input for searching the most similar knowledge.
+
+You can configure your embedding model by modifying the `embed_model_config` file.
+It supports multiple embedding models. Each embedding model will build index for all apis and knowledge independently.
+Each config of embed model should refer to  [Model Config](https://modelscope.github.io/agentscope/en/tutorial/203-model.html)
+
+For example, you can configure the embedding model of openai as below.
+
+```json5

+    "config_name": "openai_embedding_config",
+    "model_type": "openai_embedding",

+### Basic Configuration
 
 You can configure the App-Controller by modifying the `config.ini` file.
 There are several important parameters that you need to pay attention to.
