+Support multiple usages of `GuGithubActionsRole` in a single AWS account
+
+This significantly changes the resources constructed by `GuGithubActionsRole`,
+specifically, **the construct will no longer instantiate a `GitHubOidcProvider`**.
+This is because you can only ever have one `GitHubOidcProvider` per provider
+domain (ie `token.actions.githubusercontent.com`) - while we may want multiple
+instances of `GuGithubActionsRole` in an AWS account, we can't have the
+`GuGithubActionsRole` construct trying to make a new `GitHubOidcProvider` with
+each instance.
+
+Consequently, you will need to instantiate the `GitHubOidcProvider` elsewhere
+as a singleton. At the Guardian, we do this with https://github.com/guardian/aws-account-setup.

 AWS CDK implements an OIDCProvider as a custom resource.
 This requires a lambda to be deployed into the account.
 As far as I can tell, the lambda is automating the setting of `ThumbprintList`, which is quite generic.
