 ### Metadata
 
 The following types are represented in Front50 ([data models](https://github.com/spinnaker/front50/tree/master/front50-core/src/main/groovy/com/netflix/spinnaker/front50/model)):
 
-| *Type* | *Description* |
-| ------ | ------------- |
-| Application | Defines a set of commonly named resources managed by Spinnaker (metadata includes name, ownership, description, source code repository, etc.). |
-| Application Permission | Defines the group memberships required to read/write any application resource. |
-| Entity Tags | Provides a general purpose and cloud agnostic tagging mechanism. |
-| Notification | Defines application-wide notification schemes (email, slack and sms). |
-| Pipeline | Defines a reusable delivery workflow (exists within the context of a specific application). |
-| Pipeline Strategy | Defines a custom deployment strategy (exists within the context of a specific application). |
-| Project | Provides a (many-to-many) grouping mechanism for multiple applications. |
-| Service Account | Defines a system identity (with group memberships) that can be associated with one or more pipeline triggers. |
