+## Code execution
+
+We strongly recommend using docker to execute code. There are two ways to use docker:
+
+1. Run autogen in a docker container.
+2. Run autogen outside of a docker, while perform code execution with a docker container. For this option, make sure the python package `docker` is installed. When it is not installed and `use_docker` is omitted in `code_execution_config`, the code will be executed locally (this behavior is subject to change in future).
