-If you are a **pipenv** user you can quickly setup testing environment by
-using Make commands:
+We use `poetry <https://python-poetry.org/>`_ as dependency management and packaging tool.
+
+.. code-block:: bash
+
+    $ cd djoser
+    $ poetry install
+
+This will create a virtualenv with all development dependencies.
+
+To activate the virtual environment run
+
+.. code-block:: bash
+
+    $ poetry shell
+
+To run tests outside of tox, install test dependencies with:
+
+..code-block:: bash
+
+    $ poetry install -e test
+
+We also preapred a convenient ``Makefile``
 
 .. code-block:: bash
 
     $ make init
     $ make test
 
-Otherwise, if you cannot use Make commands, please create virtualenv and install
-requirements manually:
+Without poetry
+--------------
+
+New versions of ``pip`` can use ``pyproject.toml`` to build the package and install its dependencies.
 
 .. code-block:: bash
 
-    $ pip install django djangorestframework
-    $ pip install -r requirements.txt
+    $ pip install .
 
 .. code-block:: bash
 
     $ cd testproject
     $ ./manage.py test
 
+Tox
+---
+
 If you need to run tests against all supported Python and Django versions then invoke:
 
 .. code-block:: bash
 
-    $ pip install tox
-    $ tox -p all
+    $ poetry run tox -p all
+
+Example project
+---------------
 
 You can also play with test project by running following commands:
 
 .. code-block:: bash
 
-    $ ./manage.py migrate
-    $ ./manage.py runserver
+    $ make migrate
+    $ make runserver
+
+Commiting your code
+-------------------
+
+Before sending patches please make sure you have `pre-commit <https://pre-commit.com/>`_ activated in your local git repository:
+
+.. code-block:: bash
+
+    $ pre-commit install
+
+This will ensure that your code is cleaned before you commit it.
+Some steps (like black) automatically fix issues but the show their status as FAILED.
+Just inspect if eveything is OK, git-add the files and retry the commit.
+Other tools (like flake8) require you to manually fix the issues.
