-* [Python-xdg](https://www.freedesktop.org/wiki/Software/pyxdg) will place your data, config and cache in place recommended by the XDG specs (usually it’s .local/share/offpunk, .config/offpunk and .cache/offpunk). Without it, look for ~/.offpunk or ~/.config/offpunk while the cache will be in ~/.cache/offpunk/. If installation is done later, some config files may need to be migrated by hand.
 * [xdg-utils](https://www.freedesktop.org/wiki/Software/xdg-utils/) provides xdg-open which is highly recommended to open files without a renderer or a handler. It is also used for mailto: command.
 * [Python-requests](http://python-requests.org) is needed to handle http/https requests natively (apt-get install python3-requests). Without it, http links will be opened in an external browser
 * [BeautifulSoup4](https://www.crummy.com/software/BeautifulSoup) and [Readability](https://github.com/buriy/python-readability) are both needed to render HTML. Without them, HTML will not be rendered or be sent to an external parser like Lynx. (apt-get install python3-bs4 python3-readability or pip3 install readability-lxml)
