+# Installation
+
+## Python
+
+You need python 3 with the tensorflow library. We will set up a virtual envireonment to not mess up with the system.
+To do that you will need [virtualenv](https://virtualenv.pypa.io/en/stable/) and
+[virtualenvwrapper](https://virtualenvwrapper.readthedocs.io/en/latest/).
+
+One way to do it, in the correct directory (the project's one), enter the commands:
+```bash
+$ python3 -m venv env     # create the virtual envireonment, do it once
+$ source env/bin/activate # use the virtual envireonement
+
+# Here goes the install commands
+$ pip install --upgrade tensorflow
+$ pip install numpy scipy
+$ pip install scikit-learn
+$ pip install pillow
+$ pip install h5py
+$ pip install keras
+
+$ deactivate              # quit the virtual envireonment
+```
+
+Or, an other way to do it:
+
+```bash
+$ mkvirtualenv keras_tf -p python3  # create the virtual envireonment, do it once
+$ workon keras_tf                   # use the virtual envireonement
+
+# Here goes the install commands
+$ pip install --upgrade tensorflow
+$ pip install numpy scipy
+$ pip install scikit-learn
+$ pip install pillow
+$ pip install h5py
+$ pip install keras
+
+# don't know how to quit, find it yourself
+```
