Cloning and installing packages is failing because package-lock.json is present

[renatorozas]

Describe the bug
When you run the steps documented under Running locally in development mode, it will fail installing the packages because package-lock.json is present.

In order to fix this you can either:

1. Remove package-lock.json before you run npm install
2. Stop tracking package-lock.json so you don't need to run rm package-lock.json before npm install.

To Reproduce
Run the commands documented under section: Running locally in development mode.

Expected behavior
I want to be able to run the commands documented under section: Running locally in development mode without errors.
