+### Install
+
+It's highly recommended to use virtualenv to install the fittonia. my favorite
+virtualenv toolbox is [virtualenvwrapper](https://pypi.org/project/virtualenvwrapper/).
+
+So, the `workon` command on this page is related to the `virtualenvwrapper`
+package and you may use your favorite virtualenv utility such as python's
+builtin.

+```bash
+sudo apt install libpq-dev postgresql python3-dev

+Then install the fittonia:

+cd fittonia
+pip install [-e] .
