## Project Overview
This analysis pertains to the "Notes App" project, a full-stack web application designed to allow users to securely create, view, edit, and delete their personal notes. The project aims to provide an intuitive user experience with robust core functionalities and will be built following the io8 workflow principles, leveraging a cloned Angular Clarity boilerplate for the frontend foundation.

## Business Analysis
The primary business objective is to deliver a reliable and user-friendly note-taking application. The value proposition lies in providing a secure and organized digital space for users to manage their personal thoughts and information. The target audience is any individual needing a simple, effective, and accessible tool for note creation and organization. The project will initially focus on core functionalities (MVP) and then expand to enhanced features, ensuring a solid foundation and user satisfaction.

- Users must be able to edit the title and content of an existing note.
- Users must be able to delete notes.

### User Authentication
- Users must be able to register for a new account.
- Users must be able to log in to their account.
- Users must be able to log out of their account.
