-The package package_name is used to:
-	- 
-	-
+Este é um exemplo de **pacote Python simples**, criado com o objetivo de servir como base para projetos futuros. Ele foi desenvolvido para praticar a estruturação de pacotes, a organização do código, a criação de funções reutilizáveis e a escrita de testes unitários.
 
-## Installation
+---
 
-Use the package manager [pip](https://pip.pypa.io/en/stable/) to install package_name
+## ✨ Objetivo
 
-```bash
-pip install package_name
-```
+- Compreender como criar um pacote Python reutilizável.
+- Praticar a separação de responsabilidades em arquivos diferentes.
+- Aprender a estruturar um projeto com testes e dependências.
+- Treinar o uso de `setup.py` e `requirements.txt` para empacotamento e instalação.
 
-## Usage
+---
 
-```python
-from package_name import file1_name
-file1_name.my_function()
-```
+## 🚀 Funcionalidades do Pacote
 
-## Author
-My_name
+O pacote contém **duas funções principais**:
+
+### ✅ `say_hello(name: str) -> str`
+
+Retorna uma saudação personalizada com o nome fornecido.
