+### Install with virtualenv

 virtualenv --python=python[3.6|3.7|3.8] venv
 source venv/bin/activate
 pip install -r requirements.txt
 ```
 
+### Install with pipenv

+pip install pipenv
+pipenv install

+
+#### Advantages over plain pip and requirements.txt
+[Pipenv](https://pipenv.readthedocs.io/en/latest/) generates two files: a `Pipfile`and a `Pipfile.lock`.
+* `Pipfile`: Is a high level declaration of the dependencies of your project. It can contain "dev" dependencies (usually test related stuff) and "standard" dependencies which are the ones you'll need for your project to function
+* `Pipfile.lock`: Is the "list" of all the dependencies your Pipfile has installed, along with their version and their hashes. This prevents two things: Conflicts between dependencies and installing a malicious module.
+
+For a more in-depth explanation please refer to  the [official documentation](https://pipenv.readthedocs.io/en/latest/).
