+## Writing code
+
+### Coding style
+
+#### Python style
+- Unless otherwise specified, follow [PEP 8](https://www.python.org/dev/peps/pep-0008). Use [flake8](https://pypi.org/project/flake8/) to check for problems in this area.
+- Use [isort](https://github.com/PyCQA/isort#readme) to automate import sorting.
+
+To automatize this work just configure `pre-commit` hooks in your development environment:
+```bash
+# on your virtual environment
+pip install -r requirements-dev.txt
+pre-commit install
+```
+
+#### HTML (templates)
+- Template file names should be all lowercase, using underscores instead of camelCase.
+
+  Do this: `device_detail.html`
+
+  Don't do this: `DeviceDetail.html`, `Device-detail.html`
