 ## Layers
 
 Folder swh/web/ui/:
 
 - api            main api endpoints definition (api)
 - views          main ui endpoints (web app)
 - service        Orchestration layer used by api/view module.
                  In charge of communication with `backend` to retrieve

 - backend        Lower layer in charge of communication with swh storage.
                  Used by `service` module.
 
 In short:
 1. views -depends-> api -depends-> service -depends-> backend     ----asks----> swh-storage
 2. views <- api <- service <- backend                             <----rets---- swh-storage
 
 ## Utilities
 
 Folder swh/web/ui/:
 
 - apidoc         Browsable api functions.
 - exc            Exception definitions.
 - errorhandler   Exception (defined in `exc`) handlers.
                  Use at route definition time (`api`, `views`).
 - renderers      Rendering utilities (html, json, yaml, data...).
                  Use at route definition time (`api`, `views`).
 - converters     conversion layer to transform swh data to serializable data.
                  Used by `service` to convert data before transmitting to `api` or `views`.
 - query          Utilities to parse data from http endpoints.
                  Used by `service`
 - upload         Utility module to deal with upload of data to webapp or api.

 ### About apidoc
 
-This is a 'decorator tower' that stores the data associated with the documentation upon loading
-the apidoc module. The top decorator of any tower should be @apidoc.route(). Apidoc raises an
-exception if this decorator is missing, and flask raises an exception if it is present but not at
-the top of the tower.
