+# Imersão DevOps - Alura Google Cloud
+
+Este projeto é uma API desenvolvida com FastAPI para gerenciar alunos, cursos e matrículas em uma instituição de ensino.
+
+## Pré-requisitos
+
+- [Python 3.10 ou superior instalado](https://www.python.org/downloads/)
+- [Git](https://git-scm.com/downloads)
+- [Docker](https://www.docker.com/get-started/)
+
+## Passos para subir o projeto
+
+1. **Faça o download do repositório:**
+   [Clique aqui para realizar o download](https://github.com/guilhermeonrails/imersao-devops/archive/refs/heads/main.zip)
+
+2. **Crie um ambiente virtual:**
+   ```sh
+   python3 -m venv ./venv
+   ```
+
+3. **Ative o ambiente virtual:**
+   - No Linux/Mac:
+     ```sh
+     source venv/bin/activate
+     ```
+   - No Windows, abra um terminal no modo administrador e execute o comando:
+   ```sh
+   Set-ExecutionPolicy RemoteSigned
+   ```
+
+     ```sh
+     venv\Scripts\activate
+     ```
+
+4. **Instale as dependências:**
+   ```sh
+   pip install -r requirements.txt
+   ```
+
+5. **Execute a aplicação:**
+   ```sh
+   uvicorn app:app --reload
+   ```
+
+6. **Acesse a documentação interativa:**
+
+   Abra o navegador e acesse:  
+   [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs)
+
+   Aqui você pode testar todos os endpoints da API de forma interativa.
+

+
+## Estrutura do Projeto
+
+- `app.py`: Arquivo principal da aplicação FastAPI.
+- `models.py`: Modelos do banco de dados (SQLAlchemy).
+- `schemas.py`: Schemas de validação (Pydantic).
+- `database.py`: Configuração do banco de dados SQLite.
+- `routers/`: Diretório com os arquivos de rotas (alunos, cursos, matrículas).
+- `requirements.txt`: Lista de dependências do projeto.
+
+---
+
+- O banco de dados SQLite será criado automaticamente como `escola.db` na primeira execução.
+- Para reiniciar o banco, basta apagar o arquivo `escola.db` (isso apagará todos os dados).
