-
-[![Build Status](https://travis-ci.com/pimoroni/max30105-python.svg?branch=master)](https://travis-ci.com/pimoroni/max30105-python)
-[![Coverage Status](https://coveralls.io/repos/github/pimoroni/max30105-python/badge.svg?branch=master)](https://coveralls.io/github/pimoroni/max30105-python?branch=master)
-[![PyPi Package](https://img.shields.io/pypi/v/max30105.svg)](https://pypi.python.org/pypi/max30105)
-[![Python Versions](https://img.shields.io/pypi/pyversions/max30105.svg)](https://pypi.python.org/pypi/max30105)
-
-The MAX30105 is an precision optical sensor that can be used to measure heart rate, pulse oximetry (SPO2 / blood oxygen saturation), and smoke (and other particles).
-
-# Installing
-
-Stable library from PyPi:
-
-* Just run `sudo pip install max30105`
-
-Latest/development library from GitHub:
-
-* `git clone https://github.com/pimoroni/max30105-python`
-* `cd max30105-python`
-* `sudo ./install.sh`
-
-# Important!
-
-**This code should not be used for medical diagnosis, as the basis for a real smoke or fire detector, or in life-critical situations. It's for fun/novelty use only, so bear that in mind while using it.**
