How to change ACCOUNT_ID

Hello,I'm trying to run FedML on a Kubernete clusters. According to the tutorial:
"The entire workflow is as follows:
In the file ./install_on_k8s/fedml-edge-client-server/deployment-client.yml, modify the variable ACCOUNT_ID to your desired value
Deploy the fedml client: kubectl apply -f ./install_on_k8s/fedml-edge-client-server/deployment-client.yml
In the file ./install_on_k8s/fedml-edge-client-server/deployment-server.yml, modify the variable ACCOUNT_ID to your desired value
Deploy the fedml server: kubectl apply -f ./install_on_k8s/fedml-edge-client-server/deployment-server.yml
Login the FedML MLOps platform (https://open.fedml.ai), the above deployed client and server will be found in the edge devices "

My question is :
What does "modify the variable ACCOUNT_ID to your desired value" mean? What is my desired value?
Also,after I logged into the FedML MLOps platform, I can only find my account and API key in my profile. How does this relate to the desired value mentioned in the tutorial? Thank you.
