-Running qutebrowser with tox
--------------------------------
-
-Once you have cloned the repository, you can run tox inside the qutebrowser
-repository to set up a
-https://docs.python.org/3/library/venv.html[virtual environment]:
-
-----
-$ tox -e mkvenv
-----
-
-This installs all needed Python dependencies in a `.venv` subfolder. The
-system-wide Qt5/PyQt5 installations are symlinked into the virtual environment.
-
-You can then create a simple wrapper script to start qutebrowser:
-
-----
-#!/bin/bash
-~/path/to/qutebrowser/.venv/bin/python3 -m qutebrowser "$@"
-----
-
-If you regularly use a non-development version of qutebrowser, you may want to
-redirect your development version it to a local config using the `-c` flag:
-
-----
-#!/bin/bash
-~/path/to/qutebrowser/.venv/bin/python3 -m qutebrowser -c .qutebrowser-local "$@"
