 ## Configuration
 
-The configuration file (`.config.yaml`) should contain the following fields:
+The default configuration filename is `.config.yaml` (it is searched in the current working directory).
+Use the command `cmm config --create <FILENAME>` to create a default configuration:
 
-- `openai`:
-  - `api_key`: Your OpenAI API key.
-  - `model`: The name of the OpenAI model to use (e.g. "text-davinci-002").
-  - `temperature`: The temperature value for the model.
-  - `max_tokens`: The maximum number of tokens for the model.
-  - `top_p`: The top P value for the model.
-  - `frequency_penalty`: The frequency penalty value.
-  - `presence_penalty`: The presence penalty value.
-- `system`: The system message used to set the behavior of the AI.
-- `db`: The directory where the question-answer pairs are stored in YAML files.

+db: ./db/
+ais:
+  myopenai:
+    name: openai
+    model: gpt-3.5-turbo-16k

+    system: You are an assistant

+
+Each AI has its own section and the name of that section is called the 'AI ID' (in the example above it is `myopenai`).
+The AI ID can be any string, as long as it's unique within the `ais` section. The AI ID is used for all commands that support the `AI` parameter and it's also stored within each message file.
