Fundamental instructions missing from documentation

On both the readme and the site, these are the instructions:

Getting Started

Install the BundleWatch package:

• NPM: npm install bundlewatch --save-dev
• Yarn: yarn add bundlewatch --dev

Add some basic configuration to your package.json

{
    "name": "my package name",
    "version": "0.0.1",
    "bundlewatch": {
        "files": [
            {
                "path": "myfolder/*.js",
                "maxSize": "100kB"
            }
        ]
    }
}

Usage:

• NPM: npm run bundlewatch
• Yarn: yarn run bundlewatch

This will give you command line output. If you want BundleWatch to report build status on your pull requests, see below.

Now run the last command:

❯ npm run bundlewatch
npm ERR! missing script: bundlewatch

It would also be super nice if the format of the .json file provided to --config were documented.

And also that before the PR Action starts working, it needs to be pushed to the default branch, otherwise you get this when trying to add it in a PR:

[INFO] Retrieving comparison
