+Source code
+"""""""""""
+
+You can check out the latest sources with the command:
+
+.. code-block:: sh
+
+   git clone https://github.com/mind-inria/hidimstat.git
+
+Test suite
+""""""""""
+
+For testing, we recommend you install the test dependencies with pip:
+
+.. code-block:: sh
+
+   pip install -e '.[test]'
+  
+This will install ``pytest`` and the following extensions: 
+``pytest-cov``, ``pytest-randomly``, ``pytest-xdist``, ``pytest-html``,
+``pytest-timeout``, ``pytest-durations``
+
+After this installation, you can launch the test suite:
+
+.. code-block:: sh
+
+   pytest test
+
+Examples
+""""""""
+
+To run the examples, we recommend you install the example dependencies with pip:
+
+.. code-block:: sh
+
+    pip install -e '.[example]'
+
+For running the examples, it's necessary to install Matplotlib >= |MatplotlibMinVersion| and seaborn >=
+|SeabornMinVersion|.
+
+| After this installation, you can run any example in the `examples <https://github.com/mind-inria/hidimstat/tree/main/examples>`_ folder.
+| Or you can download some of them from the `documentation <https://hidimstat.github.io/dev/auto_examples/index.html>`_.
+
+Documentation
+"""""""""""""
+
+The documentation is built with Sphinx. We recommend you install the documentation dependencies with pip:
+
+.. code-block:: sh
+
+    pip install -e '.[doc]'
+
+After this installation, you can build the documentation from the source using the Makefile in doc_conf:
+
+.. code-block:: sh
+
+    make html
