 # 07 - Code quality
 
-In Lesson [04 - Professional Project](../04-professional-project) we created a repo and website for an old project developed during the course. Now we are going to improve its quality by fixing the issues each group found using a linter tool. 
+In Lesson [04 - Professional Project](../04-professional-project) we created a repo and website for an old project developed during the course. Now we are going to improve its quality by fixing the issues from each group by using a **linter** tool. 
+
+**Linters** analyze your code for potential errors, enforce coding standards, improve readability and security. They are useful tools to ensure high-quality of coding. Some popular Python linter tools:
+
+1. **Flake8:**
+Combines tools like PyFlakes, pycodestyle, and McCabe.
+Detects syntax errors, style guide violations (PEP 8), and cyclomatic complexity.
+Lightweight and easy to integrate into CI/CD pipelines.
+![](./Flake8.png)
+
+2. **Pylint:**
+Comprehensive linter that checks for errors, enforces coding standards, and suggests code refactoring.
+Provides a detailed score for your code quality.
+Highly configurable, but may require some setup to avoid excessive warnings.
