+- Initialize a Python virtual environment for loki. To do this you have to make sure you have the Python module `venv` then run `python -m venv path/to/venv` where `path/to/venv` is the path to your virtual environment. Test your virtual environment by running `path/to/venv/bin/python --version`.
+Upgrade your virtual environment modules for `pip`, `setuptools`, and `wheel` by running `path/to/venv/bin/python -m pip install --upgrade pip setuptools wheel`.
+- Install libraries ```path/to/venv/bin/python -m pip install colorama yara-python psutil rfc5424-logging-handler netaddr```
+- Run loki-upgrader.py ```path/to/venv/bin/python path/to/loki/loki-upgrader.py``` where `path/to/loki` is the path of the Loki repository.
