## Overview

This Flask social microblog lets signed-in users publish posts, browse followed users’ and public feeds, search posts, and manage profiles and follows; authentication includes registration and password resets. Routes orchestrate form validation, handler logic, and the SQLAlchemy models. Search indexing, email, language detection, localization, and error pages are supporting capabilities. The README documents Flask setup and translation support. Some modules are unsampled; edges involving them are included only where the source index or README establishes the relationship.

Main entry points: [`app/__init__.py`](https://github.com/towareesh/practice_flask/blob/master/app/__init__.py) (Flask app factory), [`app/main/routes.py`](https://github.com/towareesh/practice_flask/blob/master/app/main/routes.py) (Feed and search routes), [`app/user/routes.py`](https://github.com/towareesh/practice_flask/blob/master/app/user/routes.py) (Profile and follow routes), [`app/models.py`](https://github.com/towareesh/practice_flask/blob/master/app/models.py) (User and post models)
