Hi everyone,

the readme only shows how to do the development installation in conda.

here is how i managed with virtualenvwrapper in linux, maybe it's worth adding to the readme!

1. Installing npm with yarn:

sudo apt install npm
npm install yarn

2. Creating a virtual environment

mkvirtualenv widget_dev
workon widget_dev

3. Installing the widget and adding the virtual environment as an IPython Kernel:

pip install -e ".[test, examples]"
ipython kernel install --name widget_dev --user

In jupyter lab, one can then select the widget_dev kernel on the top right In jupyter notebook, under the menu section Kernel
