Capstone Project: Entity Relationship Diagram

In the README.md of your capstone project, create an entity-relationship diagram with mermaid.

Here’s an example Entity-Relationship Diagram that describes the data and associations in the blog project.

erDiagram
User {
  string username
  string email
  string password
  string hashed_password
  naive_datetime confirmed_at
}

Post {
    string title
    text content
    date published_on
    boolean visibility
}

CoverImage {
    text url
    id post_id
}

Comment {
  text content
  id post_id
}

Tag {
    string name
}

User |O--O{ Post: ""
Post }O--O{ Tag: ""
Post ||--O{ Comment: ""
Post ||--|| CoverImage: ""

See https://mermaid.js.org/syntax/entityRelationshipDiagram.html for the syntax.
