+(This is a project realised for our University, it will not be maintained after and it should not be used outside of testing)
+
+Palto is a project to check students attendances at their school classes. 
+It allows teachers to create sessions containing students that should be present. 
+They can then scan their student card with the NFC technology and they will be automatically marked as present to 
+this session.
+
+# Installation
+
+1. Install `python >= 3.11`
+2. Create a virtual environment with `python -m venv ./.venv/`. The next steps will be inside it.
+3. Install the dependencies with `python -m pip install -r ./requirements.txt`.
+4. Run the program by with `python ./manage.py runserver`.
