+## Objective
+
+Run [Flake8](https://flake8.pycqa.org/en/latest/) on your Python code to ensure it adheres to PEP8
+standards and to detect various errors such as syntax errors, semantic errors, and complex code.
+Flake8 is a Python tool that glues together pycodestyle, pyflakes, and McCabe.
+
+### Global Configuration of Flake8
+
+To add configuration to `flake8` shared with any other usage of flake8 (such as manual run,
+pre-commit, etc), you can use `.flake8` configuration file. Learn more
+about [flake8 configuration](https://flake8.pycqa.org/en/latest/user/configuration.html) files.
+
+See this example:
+
+```ini
+[flake8]
+exclude = .git,__pycache__,venv,dist
+max-complexity = 10
+max-line-length = 100
+```
+
+This example ignores certain errors, sets the maximum line length to 100 characters, excludes the
+tests directory, and sets the maximum McCabe complexity to 10.
+
+## How to use it
+
+1. Configure the `.flake8` file in your repository's root directory with your desired rules.
+2. Include the flake8 template in your CI/CD configuration (see quick use above).
+3. Customize the template if it's relevant.
+
+## Add a <a href="https://flake8.pycqa.org/"><img alt="Code style: Flake8" src="https://img.shields.io/badge/Flake8-checks-blue"></a> Badge to your project README.md
+
+To display the use of Flake8 in your project, you can add the following badge to your README.md:
+
+```markdown
+<a href="https://flake8.pycqa.org/">
+    <img alt="Code style: Flake8" src="https://img.shields.io/badge/Flake8-checks-blue">
+</a>
+```
