#### Steps
1. Run `docker images --format '{{ json . }}' | pbcopy`
2. Open text editor i.e. Atom
3. Add an empty array `[]`
4. Paste the content from step 1 into the empty array
5. At the end of each hash `{}`, add a comma `,` - except the last object
6. Go to [JSON Formatter site](https://jsonformatter.curiousconcept.com/)
7. Paste into the box, hit the Process button and save the output file name as `images.json`
8. Make sure both `images.json` and `images.rb` are in the same directory
9. Run the `images.rb` file: `$ ruby images.rb`

```
$ ruby images.rb
