 ### Considerations
 
-- Checking for licenses is not supported on Enterprise Server.
+- Checking for licenses is not supported on Enterprise Server as the API does not return license information.
 - The action will only accept one of the two `license` parameters; an error will be raised if you provide both.
 - We don't have license information for all of your dependents. If we can't detect the license for a dependency **we will inform you, but the action won't fail**.

+Using the `deny-groups` option you can exclude dependencies by their group name/namespace. You can add multiple values separated by a comma.

+## Waiting for dependency submission jobs to complete
+
+When possible, this action will [include dependencies submitted through the dependency submission API][DSAPI]. In this case,
+it's important for the action not to complete until all of the relevant dependencies have been submitted for both the base
+and head commits.
+
+When this action runs before one or more of the dependency submission actions, there will be an unequal number of dependency
+snapshots between the base and head commits. For example, there may be one snapshot available for the tip of `main` and none
+for the PR branch. In that case, the API response will contain a "snapshot warning" explaining the discrepancy.
+
+In this example, when the action encounters one of these warnings it will retry every 10 seconds after that for 60 seconds
+or until there is no warning in the response.
