## Updating Code Coverage in README
48+
49+
Currently, we run a command to manually generate the code coverage shield. Follow these steps:
50+
51+
1. Run `yarn badges`
52+
2. Go into the README and change the color from `red` to `green` in this line:
53+
54+
```
55+
![Lines](https://img.shields.io/badge/Coverage-46.71%25-red.svg)
56+
```
57+
58+
NOTE: we have to manually change the color because the default is red if coverage is less than 80. See code [here](https://github.com/olavoparno/istanbul-badges-readme/blob/develop/src/editor.ts#L24-L33).
