 For triple-quoted strings, always use double quote characters to be consistent with the docstring convention in [PEP 257](https://www.python.org/dev/peps/pep-0257).

-For docstrings we use double quotes since the chance of writing a ' is higher in the documentation string of a class or a method

+### exclude in mypy
+You may need to exclude files in mypy (for example configurations and migrations files). You can get this done
+adding a regexp list called `exclude` in the `setup.cfg` file. This is an example:
 
-To convert the existing double quotes to single ones, follow these steps:
-1. In your IDE, search by the regex `/(?<!"")(?<=(?!""").)"(?!"")/`
-2. Replace the occurrences with the single quote `'`
-3. Include only the python files: `*.py`
-4. Exclude migrations files and manage.py: `*migrations*, manage.py`
-5. Check that everything is well replaced.
+```yaml
+[mypy]
+python_version = 3.10
+check_untyped_defs = True
+ignore_missing_imports = True
+warn_unused_ignores = True
+warn_redundant_casts = True
+warn_unused_configs = True

+django_settings_module = config.settings.test
+

+# Django migrations should not produce any errors:
+ignore_errors = True
+```
 
-The VS Code configuration:
-- **Search**: `(?<!"")(?<=(?!""").)"(?!"")`
-- **Replace**: `'`
-- **files to include**: `*.py`
-- **files to exclude**: `*migrations*, manage.py`
 
+#### pre-commit and mypy
+Sometimes mypy can generate issues with pre-commit, because it can't recognize some used libraries in the project.
+The error shows that doesn't find some dependencies. If that is the case, add those libraries in the `.pre-commit-config.yaml` file.
+This is an example configuration:
+
+```yaml
+  - repo: https://github.com/pre-commit/mirrors-mypy
+    rev: v0.942
+    hooks:
+      - id: mypy
