Annotate models

There is gem called annotate, that can generate annotation for models. The annotation contains the attributes of the models, so it can make them easier to understand.

Start by reviewing the repository's model definitions and the annotate gem's supported integration. Determine which models should receive generated annotations and how the project expects those annotations to be maintained. Done means the relevant models are annotated and the generated annotations accurately reflect their attributes.
