Need a todo or issue to track work item "replace `main` with a tagged version".

Currently, the reference to a document always points to a version in main branch, so the content of reference will change once there is an update in main branch, which makes the reference not valid in some scenarios. It's better to refer to a tagged version of document that the content won't change over the time.
