+Run the container using the `OPENAI_API_KEY` environment variable, and a docker volume to store cache. Consider to set the environment variables `OS_NAME` and `SHELL_NAME` according to your preferences.
 ```shell
 docker run --rm \
-           --env OPENAI_API_KEY="your OPENAI API key" \
+           --env OPENAI_API_KEY=api_key \
+           --env OS_NAME=$(uname -s) \
+           --env SHELL_NAME=$(echo $SHELL) \
            --volume gpt-cache:/tmp/shell_gpt \
-       ghcr.io/ther1d/shell_gpt --chat rainbow "what are the colors of a rainbow"
+       ghcr.io/ther1d/shell_gpt -s "update my system"
 ```
 
-When using a container, please note:
-* The \[E\]xecute option for --shell with interaction will not work, since it would try this Execute in the docker container.  
-=> setting the `SHELL_INTERACTION` environment variable to false , makes sense.
-* Since, most likely the os and shell of your container are not identical to the environment you want help with:  
-set the environment variables `OS_NAME` and `SHELL_NAME` according to your setup.
