+Currently the deployment to npm is done using API keys for Ben Meyrick's (`[email protected]`) npm account. If these need changing there are some prerequisites:
 
 ### npm account
 
 - You must be a collaborator on the @ons/design-system package
 - You may have 2FA enabled but only for authentication
 - The API token **must** be encrypted using the Travis CLI
-
-### GitHub account
-
-- You must be an administrator of the repository
-- The branch protection rules for `master` should be set to **not** apply to administrators, or Travis won't be able to update the package.json version with the latest tag
