-Coming soon.
+This will install:
 
+	- ``phys2bids`` as an editable package, which means that you can modify the program and run it without having to reinstall it every time!
+	- All the ``phys2bids`` dependencies.
+	- All the **interface** modules, that deal with the interfaces for all the file formats.
+	- All the **style** modules, such as ``flake8``, to help you linter the code!
+	- All the **documentation** modules, like ``sphinx``, so that you can build the docs locally before submitting them.
+	- All the **test** modules, like ``pytest``, in order for you to test your code locally before committing it!

+If you are planning to use file formats other than plain ``txt``, you need to install extra modules to have the right interface.
+Extra modules installation can be done with the syntax::
 
-    pip install .
+    pip3 install <package>[<extra>]
 
-If you need to install other libraries, you can call again ``pip``::
+Where ``<package>>`` is either ``phys2bids`` or ``.``, depending on whether you want to use ``pip`` or ``git`` for the installation, and ``<extra>`` is one of the following:
+
+    - ``acq``: if you plan to use native AcqKnowledge files (``.acq`` extension)
+    - ``interfaces``: for all the interfaces above.
+
+For instance, if you plan to install ``phys2bids`` and use all the interfaces, run::
+
+    pip3 install phys2bids[interfaces]
+
+.. note::
+    If you "missed" or skipped this trick when you installed ``phys2bids`` the first time, don't worry!
