%description
    Tyk is a lightweight, open source API Gateway and enables you to
    control who accesses your API, when they access it and how they
    access it. Tyk will also record detailed analytics on how your users
    are interacting with your API and when things go wrong. Tyk can act
    as an OAUTH 2.0 provider for authorization.
