Preparing for installation on Ubuntu¶

Python and basic development tools

sudo apt-get install python3-dev gcc cython python-virtualenv

Additional necessary packages for a Reahl installation
```
sudo apt-get install libxml2-dev libxslt-dev zlib1g-dev libsqlite3-0
```
The next step is to create a virtualenv.
Geckodriver and Firefox (optional)

If you want to run your own automated selenium tests, install Firefox and geckodriver as well.
```
sudo apt-get install firefox firefox-geckodriver
```
