tappy uses Pipenv to manage development. The following instructions assume that Pipenv is installed. See the Pipenv install instructions for more details.

After installing Pipenv:

$ git clone
$ cd tappy
$ pipenv install --dev --ignore-pipfile
$ pipenv shell
$ # Edit some files and run the tests.
$ pytest

The commands above show how to get a tappy clone configured. If you’ve executed those commands and the test suite passes, you should be ready to develop.
