Create README test coverage badges from istanbul reports

There are fantastic tools for coverage badges such as Coveralls but, for free, they only cover public repositories

What then if a repository is private? Bind it to a process run locally with Istanbul Readme Badges

One can follow the very README.md of the project but in short here is what is needed:

• Install it

npm i -D istanbul-badges-readme

• A README.md file with additional markup into which the badges are inserted

| Statements                | Branches                | Functions                | Lines                |
| ------------------------- | ----------------------- | ------------------------ | -------------------- |
| ![Statements](#branches#) | ![Branches](#branches#) | ![Functions](#branches#) | ![Lines](#branches#) |

• Run the script anywhere, either in a, e.g. pre-commit husky hook, or in a pure NPM script directly

node_modules/.bin/istanbul-badges-readme

• Voilà!
