## Overview

SiteComunidade is a Flask blog/community site. Visitors can browse recent posts and contact information; account holders can create accounts, log in, manage profiles, view users, and create, edit, or delete their own posts. Routes coordinate forms, persistence, and page rendering. The README is brief, so capabilities and links here are grounded in the sampled route, model, form, and app-setup code; templates and styling are represented as a presentation subsystem without inferred per-template flows.

Main entry points: [`comunidade/routes.py`](https://github.com/marcelofantin/sitecomunidade/blob/main/comunidade/routes.py) (Request handlers), [`comunidade/models.py`](https://github.com/marcelofantin/sitecomunidade/blob/main/comunidade/models.py) (User and post models), [`comunidade/__init__.py`](https://github.com/marcelofantin/sitecomunidade/blob/main/comunidade/__init__.py) (SQLAlchemy database), [`comunidade/forms.py`](https://github.com/marcelofantin/sitecomunidade/blob/main/comunidade/forms.py) (Account and post forms)
