Begin with a brief overview of the solution, its purpose, and its main features.

• Users must be authenticated to create a section.
• A section can have multiple subsections.

1. Clone the repository: git clone <repo_url>
2. Navigate to the project directory: cd project-dir
3. Install dependencies: npm install
4. Run the solution: npm run dev
5. Run the server php artisan serve

• Create a Book: Navigate to the /books endpoint and use the provided form.
• Add/Edit Sections: Once a book is created, sections can be added or edited via the book's detail page.
• Manage Collaborators: Authors can add collaborators to their books, assign roles, and manage permissions through the collaborators' management page.
• To create a section: POST /sections { "title": "Section Title", "content": "Section Content" }
• To edit a section: PUT /sections/:id { "title": "New Title" }

The codebase is well-commented, providing context for complex logic or decisions. For instance, permissions are checked before certain actions, ensuring that only authorized users can perform specific tasks.

Errors are handled gracefully, providing meaningful messages to the user. For example, if a user tries to add a collaborator that doesn't exist, they'll receive a "User not found" error.

• How do I add a collaborator to my book? Navigate to your book's detail page and use the "Add Collaborator" feature. You'll need the collaborator's email address.

• I'm a collaborator. How do I edit a section? If the author has granted you edit permissions, navigate to the section you want to edit and use the provided form.
